4	Mark insertion depth on pipe for verification

Installation Procedure

Inspect coupling for debris or damage before installation

Loosen mechanical joint clamps on both ends

Insert first pipe end until it bottoms out (check depth mark)

Tighten first clamp to specified torque (5–8 Nm typical)

Align second pipe and insert into opposite end

Tighten second clamp and verify alignment

Pressurize system and check for leaks at both connections
