Expert Reply:

The Firestone # F49ZR 18 foot length of air tubing has an outside diameter of 1/4 of an inch and an inside diameter of 5/32 of an inch. If you're using the tubing with the push fittings of an air helper spring system, it's crucial that the cuts in the tubing are perpendicular and smooth. If the cut is jagged or made at an angle, the connection will leak. AirLift offers a # AL10530 tubing cutter that will make a perfectly square cut that won't leak.
