Product Questions & Answers

what size port does this washer fit on, and is that a standard thread you'd find on most hydraulic fittings?

Question by: Sheila B on Dec 15, 2025, 5:00 PM

Sized for a G 5/8 fitting with a 14-thread pitch, this falls under the BSPP standard, which is a parallel thread profile common on hydraulic components sourced from European or British-spec equipment. The outer diameter runs 30mm with a thickness of 1.4mm. It seats between the fitting face and the port to create a reliable seal without relying on thread taper.
