PEX Tube Fittings

PEX Tube Fittings

Designed for use with PEX (crosslinked polyethylene) or copper tubing on hot or cold water distribution lines, these fittings have raised ridges that hold them firmly in place when they are inserted into tubing and secured with a clamp. They form a leak-tight seal and install without welding, soldering, glue, or solvents.

90° Elbows

Make a sharp 90° change in the direction of your tubing with these 90° elbows. They have a threaded connection on one end and a tubing connection on the other.

Brass

Polyalloy

Tees

Merge two lines or split a single line into two with these union tee fittings. They have tubing connections on all ports.

Brass

Polyalloy

Branch Tees

Combine two lines into one or split a single line into two with these tees. They have a threaded middle port set at a 90° angle to a tubing connection on either end.

Brass

Polyalloy

Couplings

Join lengths of tubing that have the same diameter with these couplings to extend your tubing run.

Brass

Reducing Couplings

These reducing couplings let you connect lengths of tubing that have different diameters.

Brass

Adapters

Choose these adapters to connect tubes with different fitting types or to change the gender of a threaded end.

Brass

Polyalloy

Swivel Adapters

Connect tubing to male-threaded fittings with these swivel adapters. They turn as the tubing is moved, which eases installation, reduces bends and kinks, and decreases the amount of stress on the line.

Brass

Stainless Steel

Polyalloy

Transition Fittings

Use these fittings to connect polybutylene pipe to PEX tubing.

Plugs

Insert these plugs into fittings or tube ends to close them off and seal out dirt and contaminants.

Brass

Polyalloy

Stub Outs

Mark where supply and drain lines will attach to fixtures using these stub outs. These short lengths of tubing have a closed end that keeps dirt and debris out of lines during rough construction. When construction is complete, the closed end is cut off and the line is connected to the fixture. Stub outs can also be installed inline with the water shut-off valve to prevent the pressurized water from slamming into the valve and creating water hammer noise.

Elbow

Elbow with Flange

Straight

Clips

Support your tubing line with these clips.

Pipe Inserts

Strengthen and reinforce tubing ends with these inserts so they maintain their shape while installing fittings.
