Product Description

DIN 908 Hexagon Socket Screw Plug with Metal Sealing Edge for Lubrication Grease Blocks

Product Overview

Seal off unused manifold or progressive distribution ports with complete confidence using our premium DIN 908 Hexagon Socket Screw Plug. Specifically engineered for high-pressure grease blocks and centralized lubrication manifolds, this parallel-threaded blanking plug features a precision-machined Type A metal sealing edge (cutting face). When torqued into place, the sharp concentric sealing ridge bites directly against the housing face, creating a permanent, highly dependable metal-to-metal barrier. It completely eliminates the need for soft washers or elastomeric seals that degrade over time.
