Product Description
Female thread type S coupler one-touch joint.
[Features]
· Twice the plug/socket pull-out strength (compared to current models.)
· Effective area: 3.8 to 82 mm^2.
· 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.
· Uses surface contact to achieve reliable sealing.
· In addition to a reduction in the body size, pressed and resin parts have been used to help deliver a thorough overall reduction in weight.
· Allows flows from either the plug side or the socket side.
