Hydraulics equipment see use under a wide
variety of conditions, and the hydraulicpacking selected must be appropriate for theequipment’s scope of applicable usage
conditions.
For example, symmetrical U-Packing has
typically been the traditional choice forhydraulic cylinder U-Packing as it can be used
for both rods and pistons. However, withrespect to cylinders used for heavy machinery,
construction equipment, and other equipmentused under harsh conditions, asymmetrical
U-Packing has often been the conventional
choice.

NEW RUBBERFLON™ O-Ring

4060

TOUGHRILE™, a trademark of VALQUA, is an oilless packing made by VALQUA.
As TOUGHRILE™ is a strategic material (or investment) as defined by the Foreign Exchange and Foreign Trade Act, any export will require
export approval in accordance with the Act.

When conducting continuous automatic installation of rubber
products, the production line can see stoppages due to products
becoming twisted during installation caused by strong resistance, andadhesion between products.
The NEW RUBBERFLON™ O-Ring has had its surface modified inorder to eliminate such defects.
This product reacts with nearly all elastomers, like nitrile, fluoro
rubber, and acrylic rubber, and forms a tightly bonded film. This film
retains high followability even after being extended, leaving it unlikely
to separate after installation, and is typically used in stationary seals(gaskets).
Uses: 1. Continuous Automated Installation Lines, 2. Component
Supply Lines, 3. Oil and Grease, 4. Equipment Seal Anchoring

BY MATERIALSOne-Ring Packing TOUGHRILE™

Our company, since our founding in 1927, started off producing
synthetic rubber V-Packing which led us to be one of the first to begin
production on O-Rings, with VALQUA actually being the first company
in Japan to receive JIS approval for JIS-standard O-Rings.
In 1964, we received Defense Agency certification for airplane-use
O-Rings MIL-P-5516B Class B AN6227 and AN6230 hydraulics
O-Rings, and began production of MIL-standard airplane-use O-Rings.
Even now, with our airplane-use packing still leading our productlineup, we continue making products under stringent product quality
management for a variety of industries, such as general-use industrial
products, nuclear power-related products, and semiconductor
manufacturing-related products.

Semiconductor Industry Related Products
As the world transitions towards a high technology
information society, the semiconductor industry has
experienced continuous and rapid technological growth. It
can be said that this phenomenon is caused by theunification and joint advancement of research anddevelopment for semiconductor manufacturing equipment
and processing technology.

Even for soft sealants, the need for contamination control, in
addition to high chemical resistance and heat resistance,
grows ever more vital. By consolidating the technologies wehave developed over our many years of business, we haveworked on meeting these needs.

Performance Comparison between the ARMOR™ Series and Other Materials

As demands for these properties continue to increase inrecent years, we developed the ARMOR™ Series for use inliquid crystal display and semiconductor manufacturing
equipment. Using the Series’ stellar performance capabilities
and outstanding cost performance as sealant products forliquid crystal display and semiconductor manufacturing
equipment, we hope to contribute to improving yourcompany’s productivity and yield.

*Ranks Listed in Table BEST A to Fair C

ARMOR™ Series
Contamination control on liquid crystal display productionlines has become a significant issue in recent years due toincreases in glass substrate sizes, and the use of highdensity plasma during processing, among other reasons. As
a result, sealants used in liquid crystal display andsemiconductor manufacturing equipment are expected tohave high degrees of purity (low amounts of componentsthat could become contaminants on wafer surfaces) andlow particle properties (low likelihood of particles arising fromsealants due to the use of plasma gas and friction).

Rubber Products for Harnesses

ARCURY™ Series
Wet processes, which comprises between 1/5 and 1/3 ofthe entire semiconductor manufacturing process, havetraditionally involved RCA cleaning, which utilizes highly
concentrated and high temperature acids, alkaline, andultrapure water as cleaning chemicals. Due to the rapid
development of finer processing technology forsemiconductors, the demand for purer cleaning chemicals
has increased,

while management of fine particles, metal contaminants,
and organic matter from contacting cleaning agents hasgrown even harsher. In order to respond to these demands
VALQUA developed the “ARCURY™” brand of sealant,
which boasts superior chemical resistance in wet processingof semiconductors and liquid crystal displays, while also

Manufacturing in the food and drink market often involves
manufacturing a variety of products at once rather than focusing
on one product at a time. When manufacturing multiple varietiesof products, the smell and taste of the manufactured products
seeping in to rubber-based sealants has heretofore been asignificant problem, as the lingering smells and tastes could betransferred on to other products, and until recently the problem
has had no effective solution. It is now possible to solve thisproblem by using odorless, PTFE-coated products in areas
where the rubber-based sealants come into contact with the
products created.

Packing for Rotating Equipment
Wilson Seal
Gland packing, mechanical seals, and oil seals, among
other varieties, are usually used as seals for rotating
equipment. Wilson seals are composite sealants developed
to act as seals for the axes of low-speed/vaccuum agitators
for which gland seals were insufficient, and, thanks in part totheir additional use in absorbing shaft runout, have alreadyseen great success in practical use.
Characteristics
Wilson seals are sealants optimized for use as rotating axis
seals for vacuum equipment.
1) The pressure is typically 1.33 × 10-4 Pa {10-6 Torr} to0.49MPa {5 kgf/cm2} (however, gland packing is also
used when pressurizing).				
The product can be used with a PV value range of
MAX 0.5 MPa · m/S {5 kgf/cm2 · m/sec}.
2) Optimized for rotating axes with significant axis
shaking. )MAX. 2mm)3) The standard material for lipper sealant is fluoro rubber,which can be used up to 120ºC. For high temperature
specifications (150ºC or greater), the product can beused through cooling with accessories like water
jackets.
4) Cheaper when compared with mechanical seals.
5) Requires the use of lubricating grease.

T-RingTypes include vacuum use, vacuum pressurization use, andpressurization use.

T-Rings can be given the same compact design possible for
O-Rings, and in addition to being useable in situations
where sliding directions overlap, they can also be used inshaking and low-speed rotation conditions. This seals iscomprised of a rubber ring with a T-shaped cross section
combined with a backup ring, and is used in a variety ofdifferent devices such as swivel joints, accumulators,
boosters, and machine tools. Note that this product is used
as a seals for our company’s cylinder valves (rapid on/off
valves), and offers stable performance.

LFR SEAL™
In addition to leak-prevention capabilities, which goes
without saying, 6 things are often expected of seals forrotating equipment: (1) compact attachment spaces, (2)reduced running torque, (3) increased pressure resistance,(4) extended lifespan, (5) improved fit, and (6) low cost.
However, no seals in the past have managed to satisfy all 6of these items, and at least one area needed to becompromised. The LFR SEAL™ is an axis seal for rotating
equipment that satisfies all six of these characteristics at
once.

Axis Seals for Rotating Products

X-Rings
The X-Ring is a nearly square ring packing with an X-shaped
cross section, and is effective as a sealant for rotating
operations. A variety of synthetic rubbers are available foruse as rubber materials, each suitable for particularapplications.

Oil seals have an extremely wide variety of applications, andthe rubber materials and shape structures used varydepending on the usage conditions. The lip that comes into
contact with the surface of the axis always retains a certain
amount of tension force, and oil seals also use garter
springs to support operations that come into contact withthe axis, and metal rings to both support the packing and to
fill the space between the oil seal and the installation slot.

Specialized Fluoro Rubber

INFLATE SEAL™

Heat Resistant Fluoro Rubber (D2570)

INFLATE SEAL™ is a product based on new ideas, and canretain sealing capabilities for long periods of time regardlessof whether the contained materials are gases, liquids, or
powders, and even if the surfaces that need sealing, forexample, on doors that need to be airtight, are modestly
distorted, deformed, or uneven.

Elastomer sealants experience significant permanent setsover time when used in heated atmospheres, thereby
reducing the reliability of their sealing performance.
Therefore, even fluoro rubber, known for its superior heat
resistance, has a limited lifespan as a sealant when used inhigh temperature environments. Compared with past,
general-use fluoro rubber seal products, D2570 has asignificantly improved compression set characteristic, andan extended lifespan as a seal, thereby making a productrequiring even fewer maintenance cycles.

This product is a hollow gasket made of rubber containing
reinforcing fabrics or just rubber by itself, is formed in avariety of shapes, such as circular shapes, frame shapes,
straight pipes, and U-shaped pipes, depending on theusage purposes and conditions, and is constructed to
exhibit it sealing capabilities through expansion by supply air,etc. into the center hollow.

Diaphragms, which are frequently used in control valves in
automation equipment, fuel pumps, and other types ofvalves, are high-performance membranes that utilize the flex
resistance, weather resistance, and gas permeability
resistance characteristics of materials such as chloroprenerubber, nitrile rubber, fluoro rubber, and silicone rubber,depending on the intended use of the diaphragm. In orderto improve pressure resistance in diaphragms, they areusually reinforced with fabrics like nylon while also being
used in conjunction with elastomers.

L.J. U-Packing
This packing sees broad use as seals for rods and pistons invarious types of cylinders, as well as for other reciprocating
sliding sections. Available in cloth-filled rubber products formid to high pressure uses, as well as synthetic rubber-only
products for low pressure uses.

TOUGHRETHANE™ Products
Solvent Resistant Fluoro Rubber (D2670)
Physical properties of solvent resistant fluoro rubber (D2670)

When immersed in solvents, elastomers tend to swell anddissolve, thereby possibly reducing its sealing capabilities.
D2670, in addition to being a fluoro rubber with chemical
resistance comparable to perfluoroelastomers, is also aparticularly low-cost elastomer sealant. It is also a cleanmaterial with few effluents, and can be used in fields likefood product and semiconductor production.
