 Features

>>

Special type of packing materials are used to suit applications in assembly lines, refrigerant charging lines and air conditioner final testing lines

>>

Designed for applications in vacuum suction and refrigerant gas charging. Automatic shut-off (open/close) valve mechanisms are used in both socket and plug. Our designed high precision mechanism endures severe operating conditions in vacuum suction applications.

>>

Design allows tight sealing of socket and plug when disconnected. The SPR series couplings withstand a vacuum of 1.3x10-1Pa (1x10-3mmHg). This enables replenishing of several refrigerants (R-134a, R-410a, R-407c) and freezing application liquids

>>

The SPR series couplings can be connected to YSP Series couplings and LCG type charging guns.

>>

SPR series couplings are approved to international JRA regulations for air conditioner and other refrigerant gases applications and manufacturing

>>

SPR series conform to SAE standards.
