## Description

Steel material, mini size, max working pressure: 3000psi, NPT 1/8 male connector.

Review: Rather pathetic attempt at a good fitting. Softer than cheese - Very disappointing. Received and fitted. Npt thread a hassle as very little in UK uses that and is more likely to be BSP. First use was a 4 bar accumulator. Sealed after a bit of effort. On the Second accumulator the threaded section parted company with the body. Very poor soft diecast looking material. Seal face is a copper washer. It may have been better with a rubber seal. Definitely not fit for "high pressure"
