Hot selling pneumatic fittings air hose connector, air tube connector

Materials: Connection, valve, valve body and unlocking sleeve: Brass or 1.***5, spring, circlip and locking balls: Stainless steel, seals: Viton (PTFE coated) 
Temperature range: **0°C to max. ***0°C 
Operating range: For liquid media with temperatures up to ***0°C, e.g. for cooling circuits on plastic machines (***0°C on request) 
Optiona: with unlocking protection (standard by stainless steel couplings) -S 
To differentiate the brass couplings easier: 
Coupling socket: Sliding sleeve made of plain brass = shut-off, sliding sleeve made of nickel-plated steel = valveless 
Coupling plug: Valve plug can automatically close to prevent leakage when couplings are disconnected or open to let fluid get through when couplings are connected. Key parts are induction hardened for a better durability.
