By Maintenance Depot Plumbing Team · Last reviewed
Quick answer
The EZ-FLO 2" compression coupling (#20593) repairs or joins 2" pipe mechanically, with no cement or soldering. The line can go back into service as soon as the nuts are tightened.
Larger lines are harder to repair, especially when water keeps seeping into the trench. The EZ-FLO 2" compression coupling (#20593) joins two pipe ends mechanically, so you can make a reliable repair without cement or soldering.

Why use a compression coupling on 2" pipe
- No cure time: the line can go back into service right after installation.
- Works in damp conditions where solvent cement struggles.
- Removable: useful for temporary set-ups or lines you may change later.
- Simple tools: a pipe cutter or saw and a wrench.
Installation steps
- Turn off the supply and drain the line.
- Cut out the damaged section with clean, square cuts.
- Wipe the pipe ends clean and remove burrs.
- Slide a nut and sealing ring onto each pipe end.
- Centre the coupling body over the gap and push the pipe ends in fully.
- Tighten each nut evenly with a wrench, then test with the water on.
Tips
- Measure the pipe's outside diameter to confirm the size before you buy.
- Support the pipe on both sides of the coupling.
- Re-check the nuts after the first day of use.
When to use a glued fitting instead
For permanent, buried pressure lines, a solvent-cemented coupling is often preferred. Maintenance Depot carries both options, plus PVC primer and cement.
Frequently asked questions
Is a compression coupling as strong as a glued joint?
For most repairs it is reliable, but for permanent buried pressure lines a solvent-welded joint is often preferred.
What tools do I need?
A pipe cutter or saw, a deburring tool or knife, and a wrench.
How do I confirm the size?
Measure the pipe outside diameter and compare it with the coupling size before buying.
