Product identity

The Banjo CAP050 is a 1/2-inch Schedule 80 polypropylene pipe cap designed for plumbing and fluid-handling systems. It provides a secure closure for female NPT threaded connections in residential, commercial or industrial installations.

Installation checks

Verify that the mating fitting has a 1/2-inch female NPT thread and is rated for Schedule 80 dimensions. Confirm the system operating pressure does not exceed 150 psi and the fluid temperature stays between -20 °F and 150 °F. Ensure polypropylene is chemically compatible with the media being conveyed.

Suitability

This cap suits installers needing a corrosion-resistant, lightweight closure for cold-water, chemical or low-pressure air lines within the stated pressure and temperature envelope. It is not intended for steam service, high-temperature process piping or applications requiring metal-thread strength or fire-rated materials.

Questions about this item

Does the Banjo CAP050 cap come with any gaskets or thread sealant, or do I need to buy those separately?

The cap is supplied as a single polypropylene fitting with FNPT threads; gaskets and thread sealant are not included and must be purchased separately if required for your installation.

The listing mentions both 150 psi and 300 psi — which pressure rating should I use when selecting this 1/2" Schedule 80 cap?

The manufacturer highlights a 300 psi maximum pressure for the Schedule 80 rating, while the detailed specifications list a 150 psi max pressure; design to the lower 150 psi figure for safe operation.

How does the -20 °F to 150 °F temperature range affect the cap's pressure performance in a real plumbing system?

Polypropylene strength decreases as temperature rises, so the 150 psi pressure rating applies at the lower end of the range; at temperatures approaching 150 °F the allowable working pressure will be lower.
