Question by: Ralph P on Mar 11, 2026, 8:33 AM
fitting says it needs a square edge cut on the tube before inserting, how particular are they about that, and what happens if the cut ain't perfectly square?
Answer by: Customer Support on Mar 12, 2026, 10:04 AM
A clean, square cut matters more than most folks expect with push-connect fittings like this one. The collet grips the tube by biting evenly around the full circumference, so if the end is angled or ragged, you can end up with a weak hold or a slow leak instead of a solid seal. A good tubing cutter gets you there without much fuss. Once the end is clean and square, push the tube straight in until you feel it hit a firm stop. That's how you know it's seated right.

Will this fitting work with standard nylon air brake tubing?
Answer by: Customer Support on Sep 28, 2025, 7:20 PM
Yes, this Push>Connect fitting is designed for use in air brake systems, and it meets D.O.T. FMVSS 571.106 and SAE J1131 standards, so it's suitable for that purpose. Just be sure to make a square edge cut on the tubing before you insert it.
