Brass Cap for 1/8-Inch FNPT Piping

This brass pipe cap seals a 1/8-inch FNPT threaded opening in Class 150 piping systems. It is intended for plumbers and maintenance technicians who need a reliable closure for low-pressure water, air or oil lines. The fitting meets ASA, ASME and SAE standards for dimensional accuracy and thread quality. It is supplied new and ready for installation with thread sealant.

Rated for 1200 psi Maximum Pressure

The single specification that determines suitability is the 1200 psi maximum pressure rating at Class 150. Systems operating above this pressure require a higher-class fitting. The cap is manufactured from brass to provide corrosion resistance in typical plumbing and pneumatic applications. Verify your system pressure before selecting this component.

Operating Range From Minus 65 to 250 Degrees F

In normal use the cap handles temperatures from minus 65 to 250 degrees Fahrenheit without degradation of the brass body or thread seal. The material does not generate noise or draw power as it is a static sealing component. Thermal expansion remains consistent with standard brass alloys across the stated range. California Proposition 65 warnings apply for chemical content.

Questions about this item

What does the 1200 psi rating mean when the cap is installed on a pipe?

The 1200 psi figure is the maximum pressure the brass cap can hold at its Class 150 rating; it should not be exceeded in service.

Which thread standard does the 1/8 inch FNPT connection follow, and what does that limit?

The FNPT threads conform to ASA, ASME and SAE standards, limiting the cap to tapered pipe threads that seal on the flanks.

What size opening does the 1/8 inch FNPT cap need to fit onto?

It threads onto a male 1/8 inch NPT pipe end, requiring a matching tapered external thread for a sealed joint.
