	To make a connection, the tube is simply pushed in by hand; the unique collet locking system then holds the tube firmly in place without deforming the tube or restricting flow.
	Start by pushing the tube into the fitting and up to the tube stop.
	After the tube has been inserted, pull on the tube to check that it is secure.
	It's a good idea to use a simple tube cutter for a square cut and to remove burrs and any sharp edges.
	To disconnect, ensure that the system is depressurized, push the collet square against the fitting. With the collet held in this position the tube can be removed.

Abbreviations/Terms

O.D. -- Outside Diameter NPT -- National Pipe Thread NPTF -- National Pipe Thread Female (threads on the inside of fitting) UNS -- Unified National Special (see F.A.Q. directly below) EPDM -- Ethylene Propylene Diene Monomer (rubber) Thread UNS -- Unified National Special threads - see explanation in FAQs below for more info

"Do you offer John Guest fittings in larger sizes?" We do, please click here for larger push fit quick connect fittings. "I have heard of National Pipe Threads (NPT) but what does 'Thread UNS' mean?" UNS stands for "Unified National Special" threads. The 7/16" x 24 threads on this fitting are a special 1/4" od compression female thread, (same female thread as a brass compression nut). This special fitting is used to attach directly to the male inlet threading on filter faucets that have 1/4" compression inlets. "What are the locking clips used for?" The locking clips are used for extra protection when a Quick Connect Push-In fitting is used excessively and the tubing is removed and reinserted a lot. The locking clips are to be inserted directly behind the collet.
