Things You’ll Need:

Pipe Cutter
Adjustable Wrench

Step1

If your putting the valve in the middle of a section of pipe you'll first have to cut the pipe to install the valve. Make sure you don't cut the pipe two short. You'll want each end of the pipe to slide into the valve at least 1/4".

Step2

Then slide the nut onto each side of the pipe, then the compression ring is slid on.

Step3

1/2 Slide the end of the pipe into the valve. Slide the nut to the threaded end of the valve.

Step4

Tighten the nut onto the valve. As the nut is tightened, the compression ring compresses the pipe in the seat. Amazing no leaks.

Tips & Warnings

Make sure the pipe is pushed all the way into the fitting. This is a common mistake which will result in a leak.
Be careful when bending the pipe, a compression ring will not slide over a bend in the pipe. If you have to bend the pipe make sure the last few inches remain straight.
