08 SQUARE HEAD PIPE PLUG

Description & Features

A 1/2-14 Male NPTF thread makes this straight steel square head pipe plug a reliable choice for sealing unused ports in hydraulic circuits and industrial fluid systems. Manufactured to SAE J476, the thread form ensures a pressure-tight mechanical seal without reliance on sealant tape alone, which suits demanding industrial environments where thread integrity is critical.

The 08 Square Head Pipe Plug is part of Brennan Industries' 5406-SHP series and is constructed from straight steel for durability in standard hydraulic service. The square head profile accepts a wrench for straightforward installation and removal, making it practical in confined port locations. Overall length is 1.020 mm, with a drill size of 0.531 at the threaded end. California residents should note that this product is subject to Prop 65 warning requirements.
