Introduction
Push-to-pull, push-to-connect, push-in, push-fit, or instant fittings are a type of easily removed compression fitting or quick connect fitting that allows an air (or water) line to be attached, nominally without the use of tools (a tool is still usually required for cutting tubing to length and removal). These fittings act similar to the way regular compression fittings work, but use a resilient O-ring (normally EPDM) for sealing, and a grip ring (normally stainless steel) to hold the tube in place.
These fittings can be used on all sorts of pipe of many sizes for many purposes.
The main advantages of this technology over traditional soldered copper or glued plastic are that fittings can easily be unmounted and re-used, speed of assembly, assembly when wet and that the joints are still rotateable after connection.
Challenges
There are a dizzying variety of hoses, pipes, couplers, fittings, adapters, and other plumbing fixtures. How can we reduce complexity while retaining broad compatibility.
Approaches
Wherever possible, Replimat prefers to use Push fit compression fittings for moving liquid and air. Efforts are directed toward adapting existing fittings to this system.
