A spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect couplings.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.
