Merit Brass XNL116-12 Brass Pipe Cap 3/4 Inch Fnpt

Product Description

The MERIT BRASS XNL116-12 is a 3/4-inch brass pipe cap with a female NPT (FNPT) end style, rated for 125 lb service. Pipe caps are used to terminate the end of a threaded pipe run, sealing off the line from flow or pressure. This cap is made from brass, delivering reliable corrosion resistance in potable water, low-pressure steam, and general plumbing applications. The rough finish indicates an unpolished exterior, standard for utility and trade installations. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This pipe cap is suited for residential and light commercial plumbing systems where a 3/4-inch NPT termination is required. Common applications include capping off branch lines, temporarily or permanently sealing unused ports on manifolds, and closing out test points in distribution piping. The FNPT thread engages directly onto a male NPT pipe end for a secure, pressure-rated connection.

Key Features

• 3/4-inch nominal pipe size with FNPT thread for direct installation onto male NPT pipe ends
• 125 lb pressure rating suitable for standard plumbing and low-pressure steam service
• Brass construction provides corrosion resistance in water and steam systems
• Rough exterior finish standard for utility and concealed installations
• Compact cap design permanently or temporarily seals threaded pipe ends

Compatibility

Designed as an OEM-style threaded fitting for use with standard 3/4-inch male NPT pipe ends in 125 lb-rated brass fitting systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a pipe wrench and thread sealant or PTFE tape applied to the male NPT threads per IPC guidelines. Shut off and depressurize the line before installing or removing any pipe cap. Do not overtighten brass fittings, as the material is softer than iron and can crack under excessive torque. Verify system pressure rating does not exceed the 125 lb rating of this fitting.
