Pioneer Hex Socket Pipe Plug NPT Pack

Pioneer Hex Socket Pipe Plugs are NPT (National Pipe Taper) plugs for sealing unused or temporary ports in engines, fluid systems and general automotive and industrial plumbing. Each plug has an internal hex socket, also called an Allen head, so you can install and remove it with a standard hex key or Allen wrench.

Key Features:

• Tapered NPT external threads seal threaded ports
• Internal hex (Allen) socket drive allows secure tightening with a hex wrench
• Low-profile head sits neatly in the port for a clean look
• Steel construction for durability and long service life
• Suited to oil, fuel, coolant and other fluid passages, including engine blocks, cylinder heads, oil pans and transmission cases

Pioneer has supplied automotive parts since 1946, including motor mounts, fittings, cables and accessories. These plugs are a practical choice for engine builders, repair shops and enthusiasts who need to close off ports reliably. Use thread sealant appropriate to the application when installing.
