Komatsu Swivel Cap (33 X 1.5)

That's what this cap is built for. The connection side accepts an M33 x 1.5 female thread at 33mm, so if your open Komatsu port matches that spec, you're good to go. It's steel, made by Adaptall, and the swivel design makes it a whole lot easier to thread on without fighting the alignment.

it's made for capping off and guarding those open Komatsu ports during servicing, storage, or when you're redoing the system. Keeps the gunk out.

Built for Komatsu style hydraulic connections, it threads onto an M33 x 1.5 female port and caps it off to protect the opening during service, storage, or when you are changing the system around.
