Metric Countersunk Sealed Plug

Description & Features

Designed for sealing unused or inactive ports in hydraulic circuits, this Metric Countersunk Sealed Plug from Adaptall provides a clean, flush-fitting closure for M14 x 1.5 metric threaded ports. The countersunk profile allows the plug to sit recessed at the port face, which is useful where clearance or surface profile is a concern in compact assemblies.

Constructed from steel, the plug measures 16.7mm in length with a 19mm wrench width, making it compatible with standard tooling. The male M14 x 1.5 thread configuration suits a wide range of metric hydraulic components and manifolds where a reliable, low-profile port closure is required.

Question by: Scott W on Apr 22, 2025, 1:05 PM

Got an M14 x 1.5 port on a manifold block just sitting open and I need something flush with the surface, this gonna work for that?

That countersunk profile is exactly what handles that situation. The plug seats recessed at the port face rather than protruding, so you get a clean, flush closure that won't interfere with adjacent components or clearance-tight assemblies. The M14 x 1.5 male thread matches standard metric hydraulic manifold ports, and at 16.7mm in length it's a compact fit. A 19mm wrench is all you need to drive it in with standard tooling.
