Product Description
An S coupler / one-touch joint joint with improved plug/socket pull-out strength.
[Features]
· Equipped as standard with a sleeve cover.
· Shock resistance has been improved by changing the lock ring to shock-resistant PBT.
· The loss of effective area is minimized because there is no valve spring to block the flow path.
· The check valve end configuration facilitates a rectifying effect.
· A sealing structure with low leakage.
· Employs a unique connection method.
[Applications]
· Fluids used: air, water.
