P/C 1/2 NPT Pipe Plug

The P/C 1/2 NPT Pipe Plug from Russell is a precision-engineered hydraulic and pneumatic fitting designed to seal threaded ports and terminate unused lines in fluid power systems. This aluminum plug serves critical roles across industrial machinery, automotive hydraulic circuits, and tactical equipment platforms where reliable port closure prevents contamination, fluid loss, and system failure. Whether you're assembling a custom hydraulic manifold, maintaining legacy equipment, or building out a pressure vessel, a quality pipe plug is essential for system integrity and safety.

Manufactured from aluminum and finished in black anodized coating, this 1/2 inch NPT (National Pipe Thread) fitting delivers corrosion resistance and durability in demanding environments. The Allen head design enables quick torque application with standard hex key tools, ensuring proper seat pressure without over-tightening or stripping. The NPT taper thread profile creates a metal-to-metal seal that improves with pressure, making it ideal for both static applications and systems experiencing vibration or thermal cycling. The compact form factor—weighing just 0.07 lbs and measuring 2.7 × 1.95 × 4.9 inches—allows installation in space-constrained manifolds and valve blocks without bulky protrusions.

Maintenance technicians, hydraulic system builders, and equipment manufacturers rely on Russell fittings for consistency and thread compatibility across platforms. The 1/2 NPT standard matches pump outlets, valve cavities, and manifold ports found in construction equipment, agricultural machinery, and industrial fluid power networks. Installation requires hand-tightening followed by 1–1.5 turns with an Allen wrench to seat the taper; avoid over-torquing, which can deform the aluminum body. This plug integrates seamlessly with Parker, Eaton, and Bosch Rexroth system components, making it a versatile stock item for shops managing mixed-brand fleets.
