Allen Plugs NPT 1/16in 2pk

The Allen Plugs NPT 1/16in 2pk from ALLSTAR PERFORMANCE are precision-engineered aluminum fittings designed to seal and protect NPT (National Pipe Thread) ports in various applications. These plugs are essential for blocking unused 1/16-inch NPT openings on engine blocks, manifolds, and aftermarket components where port closure is required. They are particularly useful for engineers and fabricators working on high-performance and custom engine builds.

Constructed from aluminum and finished with a black anodized coating, these fittings resist corrosion and oxidation while providing a professional appearance in engine bays. Each plug features an Allen head design for secure, tool-assisted installation and removal, allowing controlled torque application without stripping. The anodized surface ensures durability against exposure to fuel, coolant, and oil, which is critical for longevity in demanding automotive and powersports environments.

This two-pack offering is ideal for engine builders, race shops, and restoration professionals who need to block multiple NPT ports during engine assembly or upgrade work. The 1/16-inch NPT thread size ensures compatibility with standard factory and aftermarket ports commonly found on cylinder heads, intake manifolds, and auxiliary cooling components. Installation requires only a standard Allen wrench and proper thread sealant, such as PTFE tape or pipe thread sealant.
