Brass Countersunk Plug 1/8 MNPT

This brass countersunk plug provides a secure closure for 1/8 inch male NPT threaded openings in plumbing and hydraulic systems. It is designed for installers and maintenance technicians who need a reliable, flush-fitting seal in compatible piping networks.

Sustained Load Performance

The fitting meets Class 150 specifications and withstands a maximum pressure of 1200 psi across a temperature range of -65 to 250 degrees Fahrenheit. Brass construction maintains sealing integrity under continuous pressurised conditions without the deformation risks associated with plastic alternatives.

Upgrade Considerations

This plug replaces worn, corroded or missing countersunk fittings in existing ASA, ASME or SAE compliant assemblies. The jump is justified when a flush internal profile is required to prevent flow obstruction or when the broader chemical resistance of brass outweighs the cost of steel or plastic substitutes.
