Notification of Change of200MPa type Pressure Gauge

Dec.01, 2014
RIKEN KIKI CO., LTD.

mounting method
OutlineFrom Oct. 2014, new production of 200MPa type Pressure Gauge changed to that equips
new mounting part and seal method was started.
Accordingly, type of name and mounting method have been changed either, please referto details noted as below.

1 Changing of pressure gauge type, screw part, and seal method

Former type
Old type pressure gauge
Fixed screw type

Latest type
New type pressure gauge

Type : AS150-250M

Universal screw type
Tip end cone-shape

Type : AS150-250-U

Screw part magniﬁed

Screw part magniﬁed

Screw partScrew part and pressure gauge main body aredesigned as a monolithic speciﬁcation.
Pressure gauge itself should be rotated whenmounting, and nearly impossible to ﬁx thedisplay face of gauge on desired direction.
Our derivatives to solve this problem are"GA-2000" Sleeve for pressure gauge mounting,"GB-2000" Bushing for pressure gauge mounting,
we adopt the mounting method not to rotatepressure gauge itself with these items.

Seal method
Hydraulic oil is sealed with "GC-2000" Cone forpressure gauge.

Rotation of pressure gauge itself is not required
when mounting, rotate the hexagon part andfasten that.

Seal method
Tip end of screw part is cone-shaped design,
hydraulic oil is sealed with this part.
☆ "GC-2000" is not necessary.

2 Changing type of pump, bracket, branch that pressure gauge mounted on
Due to changing pressure gauge mounting method, types of each pump, pressure gauge mounting
bracket and each branch were changed accordingly. Old/New type list is shown as below.

Procedure 1

Remove pressure gauge, "GA-2000" Sleeve for pressure gauge mounting, "GB-2000" Bushing for pressure gauge
mounting and "GC-2000" Cone for pressure gauge from the pressure gauge mounting part of

Old typeequipment.

Mount "FMSU-G1/2 X M34" on the pressure gauge mounting part of

Old typeequipment, screw into that to the bottom

until butting in by hand or tool. (No need to be fastened ﬁrmly after butting in)☆ Any seal materials are not necessary on the screw part.

WARNINGBe careful not to get injured by the screw part when mounting"FMSU-G1/2 X M34" on.
