Product Questions & Answers

got a 3/4 inch copper line on a water system here and need a replacement compression nut. this gonna fit right or do i need something different?

Question by: Harvey R on Jan 31, 2026, 12:26 PM

For 3/4 inch tube OD on copper, this is the correct fit. It's made specifically for copper and aluminum tubing at that size, so you won't need an adapter or anything extra. Just keep in mind the pressure rating at that tube size runs 188 PSI working pressure with a 4:1 safety factor, so make sure that lines up with what your system is running.

Can I use this compression nut with steel tubing?

Question by: Sherry W on Mar 24, 2026, 9:19 PM

It's made for copper and aluminum tubing, so it's not recommended for steel.
