Frequently Asked Questions
What is this quick connect coupler plug used for?
This PF series plug is used to create fast, secure connections in fluid transfer systems on ships and industrial equipment. It is commonly paired with a socket to join hoses or pipes carrying hydraulic oil, compressed air, or vacuum.
How does the auto shut-off feature work?
Inside the plug, a floating ball valve is held open when connected. Upon disconnection, the valve automatically closes, preventing leaks and spills. This one-way shut-off design keeps the plug end sealed.
What thread does this coupler have?
The plug features an Rc 1/4 female pipe thread, conforming to the British Standard Pipe Taper (BSPT). It mates with any male R 1/4 (BSPT) threaded component.
Is this coupler compatible with other PF series fittings?
Yes, it is designed to connect with any standard PF series socket (coupler) of the same size. Please ensure the socket has the corresponding latch mechanism for a secure fit.
