Allen Plugs NPT 1/4in Steel 2pk

The Allen Plugs NPT 1/4in Steel 2-pack from ALLSTAR PERFORMANCE provides a reliable, compact solution for sealing NPT ports in hydraulic systems, fluid lines, and precision equipment. These steel Allen head plugs are engineered to close off unused threaded ports, preventing fluid leakage and contamination in high-pressure applications where system integrity is critical.

Each plug features a 1/4-inch NPT (National Pipe Thread) connection, the industry standard for fluid system fittings, and comes with an Allen head design for secure, hand-tool installation and removal. The zinc oxide finish provides corrosion resistance in harsh environments, extending service life in applications exposed to moisture, salt spray, or temperature fluctuations. The compact form factor—weighing just 0.06 lbs per pair—makes these plugs ideal for tight spaces and systems where weight considerations matter. NPT threading ensures a tapered, self-sealing fit without requiring additional sealant tape or compound in most applications.

This two-pack serves technicians, fabricators, and equipment builders who need reliable port closure solutions for hydraulic circuits, fuel systems, coolant lines, and pneumatic setups. The stainless steel construction and proven ALLSTAR PERFORMANCE brand heritage make this a trusted choice for both professional shops and serious DIY builders requiring repeatable, leak-free results in high-performance applications.

Whether sealing unused manifold ports on race engines, pneumatic systems, or custom fluid lines, these NPT 1/4-inch plugs deliver the dependability needed when system pressure and cleanliness are non-negotiable.
