Metric Countersunk Sealed Plug

Description & Features

Manufactured from steel, this M42 x 2.0 metric threaded plug is designed to seal unused or inactive ports in hydraulic systems. The countersunk design allows the plug to sit flush or recessed within the mating surface, making it well suited for installations where a low-profile closure is required. With a 42mm thread size and 2.0mm thread pitch, it is compatible with standard metric port configurations commonly found in hydraulic manifolds, valve bodies, and cylinder housings.

The Metric Countersunk Sealed Plug is supplied by Adaptall and measures 22.6mm in length with a 50mm across-flats width. Steel construction provides the durability and mechanical strength expected in demanding hydraulic environments. The male metric thread ensures a secure, leak-free port closure when properly torqued to specification.

got an M42 x 2.0 port on a manifold that’s not being used, is this the right plug to cap it off?

Answer by: Customer Support on Apr 5, 2026, 6:52 AM

For an unused M42 x 2.0 metric threaded port, this plug matches that thread size and pitch and is made for sealing inactive hydraulic ports on manifolds, valve bodies, and cylinder housings.
