Product Questions & Answers

If I'm using this bulkhead fitting with some soft metal tubing, will it still hold okay?
Question by: Travis A on Sep 21, 2025, 1:33 PM
This fitting is compatible with soft metal tubing, as well as polyurethane (90 durometer and above) and polybutylene tubing. The push-in design grips the tube automatically upon insertion and only tightens with pulling force or line pressure.

got 1/4" OD poly tube, does this fitting actually bite and seal without clamps or anything?
Question by: Kent R on Jun 25, 2025, 7:34 AM
Once the tube is pushed in, the gripping teeth grab the outside of the tubing and a Buna-N O-ring seals on the tube OD. Pulling on the tube or having pressure in the line only tightens the grip because the insert cams in deeper, and the tube bottoms on a positive stop for support.
