Installation Overview
Insert Pipe
Push the MDPE pipe into the fitting until the first point of resistance—no chamfering required.
Tighten Nut
Hand-tighten the compression nut. Use a strap wrench to complete tightening—avoid excessive force.
Verify Joint
Confirm the pipe is properly seated by checking that the nut is fully engaged. The fitting creates a secure seal using internal compression without needing further adjustment.
Testing
Pressure test the system to confirm a watertight seal. Check joints after testing to verify there is no movement or leakage.
