Relief Plug M18x1.5 Zero-leak with seal, for use in rear cover with relief valve

Description & Features

Designed for use in rear covers equipped with a relief valve, this M18x1.5 threaded plug from Salami S.P.A. provides a zero-leak seal in hydraulic gear pump assemblies. Part of the 2.5PB Series, the Relief Plug M18x1.5 Zero-leak with seal incorporates an integral seal to eliminate fluid bypass at the plug seat, a critical requirement in pressure-sensitive hydraulic circuits where any leakage path is unacceptable.

The male thread configuration and M18x1.5 pitch make this plug a direct-fit component for compatible Salami 2.5PB Series rear cover assemblies. Its zero-leak design is particularly suited to applications where maintaining circuit integrity under sustained pressure is essential.

Question by: Denise C on Dec 24, 2025, 8:41 PM

Will this plug work with any M18x1.5 threaded hole, or is it just for the Salami rear covers?

Answer by: Customer Support on Dec 25, 2025, 9:11 PM

It's made as a direct-fit replacement for Salami 2.5PB Series rear covers. While the M18x1.5 thread size might be physically compatible with other components, the zero-leak design is specifically intended for Salami pumps.
