Product Questions & Answers

Will this here fitting work alright with a soft copper line?
Question by: Sheila K on Apr 7, 2026, 7:44 AM
Yes, this Alkon fitting is designed for use with soft metal tubing, along with polyurethane and polybutylene.

tubing I got is polybutylene, about 3/16 OD, will that push right into this fitting or do I need something different?
Question by: Jerry H on Apr 18, 2025, 10:36 AM
Polybutylene tubing is one of the compatible types for this fitting, and the 0.19 inch tube OD is what it's built around. That works out to just about 3/16, so you're in the right range. When you push the tube in, the gripping teeth catch it and the Buna-N O-ring seals against the outside diameter. One thing worth knowing is the tubing needs to be in decent shape at the cut end, clean and square, so the teeth get a solid bite and the O-ring seats right.
