Product Questions & Answers (3)

Question by: Randy G on Mar 12, 2026, 10:43 AM
got a WALPro setup with 8mm tube, is this the right nut for it?
Answer by: Customer Support on Mar 14, 2026, 6:05 AM
For an 8 mm tube O.D. WALPro union nut, this one matches the key fit points listed: it is a WALPro Series union nut with an 8 mm tube O.D. and an M16x1.5 thread.
Question by: Carl H on Apr 11, 2025, 12:16 PM
What size tubing does this nut fit? Just want to make sure it's gonna work for my setup.
Answer by: Customer Support on Apr 13, 2025, 6:24 AM
This union nut is designed for tubing with an 8 mm outer diameter.
Question by: Hugh Y on Dec 21, 2025, 10:30 AM
Got an 8mm tube line running to a hydraulic cylinder and the original nut stripped out on me. This a straight swap for the OEM piece or do I need to worry about it not seating right?
Answer by: Customer Support on Dec 23, 2025, 6:03 AM
For an 8mm OD tube with M16x1.5 threading, this nut matches those specs directly. It's forged or drawn steel, built to current DIN standards, so the dimensions line up with what you'd expect from an OEM-spec flareless fitting in that size. As long as your existing body and sleeve are in good shape, this should seat and seal the same way the original did.
