Inert gas,
VacuumAirGasMax. Tightening TorqueClamps directly on straight copper
pipes !
Double seal construction withstands
a vacuum of up to 1.3 x 10-1 Pa.
• Clamps directly on to a straight copper pipe eliminating unnecessary welding
or flaring.
• Withstands a vacuum of up to 1.3 x 10-1 Pa (when connected) making it
possible to be used in leak testing, vacuum suction and refrigerant charge.
• Select from three standard types of seal materials to be used with fluids for
air conditioner and refrigerator production lines. Many models to suit various
pipe sizes.
• One lever operation simultaneously clamps and seals pipe. Double seal
construction for tight fit on end and outside surface of pipe ensures excellent
sealing and vacuum resistance.

Clamping Mechanism

Application Example

Before clamping
Copper pipe

After clamping
Sleeve

Chuck

Lever

Seal materials
Push down

When the lever is pushed down, the sleeve moves in the direction of the arrow, and at
the same time actuates the chucks to grip the copper pipe firmly and provide a tight seal.

Compressor pressure test
Before use, please be sure to read “Safety Guide” described at the end of this book and “Instruction Sheet” that comes with the products.
