Fittings, Valves, Tubing



Fittings, Valves, and Tubing
When plumbing your water supply at your business or home, there are a series of pipes, tubes, fittings and valves that water must travel through before reaching your sink, bathroom, or other water dispensing device. Polyethylene tubing and/or PEX tubing is flexible tubing designed for a wide variety of applications. Fittings and valves then connect to pipe or tubing to adapt to different shapes and sizes.


We offer an extensive inventory of tubing, valves, and fittings from popular manufacturers such as:
