Product Questions & Answers

Does this adapter come with everything you need to bolt it up, or do you have to go hunt down hardware separate?

Question by: Curt E on Sep 18, 2025, 10:26 AM

Everything ships together in the box. You get the mounting bolts, lock washers, and a Buna-N O-ring already included, so there's no extra trip to the supply house before you can get it installed.

got a 3.5 inch code 61 flange line, does this adapter take me over to 3.5 pipe with a socket weld end?

Question by: Joyce B on Mar 8, 2026, 7:02 PM

Built for that exact changeover, it mates a 3.50 inch SAE Code 61 4-bolt flange on the hydraulic side to a 3.50 inch pipe socket weld end on the other side, using an O-ring half face seal at the flange pad.
