  1. Cut tubing square using a tubing cutter and ensure the end is clean, burr-free, and fully round
  2. Mark the tubing with insertion depth measurement to confirm proper seating inside the fitting body

  4. Tug the tubing to verify secure engagement with the internal grab ring before pressurizing the system
COMPATIBILITY

Tubing Size & Thread Reference

The AquaLock large diameter fitting system accommodates polypropylene tubing from 3/8" OD through 1-1/8" OD, corresponding to copper tube sizes from 1/4" CTS to 1" CTS. When working with NPT threaded connections, reference the standard pipe thread chart: 1/4" NPT equals 0.540" OD actual, 3/8" NPT equals 0.675" OD, 1/2" NPT equals 0.840" OD, 3/4" NPT equals 1.050" OD, and 1" NPT equals 1.315" OD actual diameter. Verify your tubing outside diameter before selecting the corresponding AquaLock fitting size to ensure proper sealing and grab ring engagement.

🔧 Pro Tip: Keep a depth gauge or marker handy during installation. Marking the correct insertion depth on your tubing before you push it into the AquaLock fitting eliminates guesswork and prevents incomplete seating that can cause slow leaks under pressure.
