Installation Overview
Cut the tube ends square, push to full seat on both sides, then pressure test.
Preparation
Cut Tubing Square
Shut off water and relieve pressure. Use a sharp cutter for clean, square ends.
Deburr & Clean Ends
Remove burrs and wipe the tube ends dry so the seals seat smoothly.
Install
Push to Full Seat
Insert each tube straight into the union until it bottoms out.
Pull Test to Confirm Grip
Give a gentle pull on each side. The tube should hold firmly.
Support Nearby Tubing
Add a mount if needed so the union is not under strain.

Bring System to Operating Pressure
Restore water and power. Let pressure stabilize.
Inspect for Leaks & Re-seat if Needed
Watch both joints. If you see a drip, depressurize, recut square, and re-seat.
