Pipe Plugs - 3/8 (100)

Pioneer Pipe Plugs - 3/8 inch NPT (100-pack) are steel fitting plugs designed to seal threaded pipe connections in hydraulic systems, pneumatic lines, fuel systems, and general industrial applications. Each plug features an allen head socket for easy installation and removal with a standard hex key, making these plugs ideal for field maintenance, equipment assembly, and system testing where temporary or permanent pipe port closure is required.

The 3/8 inch NPT (National Pipe Thread) size matches standard industrial and mobile equipment ports, ensuring proper sealing without adapters or workarounds. Steel construction with a natural finish provides corrosion resistance suitable for most shop and field environments. The allen head design allows positive torque application, reducing the risk of stripped threads or under-tightened connections that can lead to system leaks or contamination. At 2.4 pounds, the 100-count package offers substantial inventory for maintenance shops, equipment dealers, and contractors who regularly service multiple units or maintain repair kits.

These plugs serve equipment operators, service technicians, and fleet maintenance teams who need reliable port closure solutions during repairs, storage, or system pressure testing. The bulk 100-pack format reduces per-unit cost compared to smaller quantities, making this choice economical for workshops that regularly replace or inventory plugs. Operators in agriculture, construction, automotive, and industrial sectors depend on NPT plugs to prevent fluid loss and contamination when servicing hydraulic or pneumatic systems.

3/8 inch NPT plugs are standard across most equipment classes, from light-duty pneumatic tools to heavy mobile hydraulic systems. Having a large supply on hand ensures you're never delayed by missing fittings during critical repair windows.
