Product Description
An S coupler / one-touch joint joint with double the plug/socket pull-out strength of the conventional model.
[Features]
· Constructed without the use of any steel balls, giving it a large effective area and a slim body design that will not restrict the flow path.
· Equipped as standard with a sleeve cover.
· 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.
· Uses surface contact to achieve reliable sealing.
· Allows flows from either the plug side or the socket side.
· Shock resistance has been improved by changing the lock ring to shock-resistant PBT.
· The sleeve lock mechanism helps prevent accidents caused by unexpected separation.
