FAQ

Frequently Asked questions

Q: What does "PU 08" mean?
A: "PU" indicates a Straight Union, and "08" means it is designed for 8mm OD tubing on both sides.

Q: Can I use this fitting to connect a metric tube to an imperial tube?
A: No, the LPU is for connecting tubes of the exact same size. To connect, for example, a 6mm tube to a 1/4" tube, you would need a specialized metric-to-imperial reducing union.
