Anderson Metals 756108-12 Brass Fnpt Pipe End Cap 3/4-14

Product Description

The ANDERSON METALS 756108-12 is a lead-free brass FNPT pipe end cap designed to terminate 3/4-14 female-threaded pipe ends in pressurized systems. Rated to 1,000 psi maximum working pressure, this cap provides a secure, leak-resistant seal in plumbing, fuel, and gas distribution lines. Constructed from lead-free brass, it meets requirements for use in potable water applications. Licensed plumbers, pipefitters, and gas line technicians install this fitting type during new construction, system modifications, and maintenance shutoffs where an open pipe end must be closed and pressure-tested.

This end cap is suited for residential and light commercial applications across multiple fluid and gas service types. Compatible media includes potable water, grease, fuels, LP gas, and natural gas. Its FNPT (female national pipe taper) thread form creates a tapered mechanical seal when paired with a matching male NPT pipe end. It is a standard choice in gas rough-in work, compressed-air branch shutoffs, and plumbing pressure tests where a threaded cap is required to isolate a line segment.

Key Features

• 1,000 psi maximum working pressure rating for use in pressurized piping systems
• Lead-free brass construction meets potable water compliance requirements
• FNPT connection type forms a tapered thread seal on standard NPT male pipe ends
• 3/4-14 thread size fits standard 3/4-inch NPT pipe fittings
• Approved media includes potable water, grease, fuels, LP gas, and natural gas

Compatibility

Designed for use with potable water, grease, fuels, LP gas, and natural gas piping systems using standard 3/4-14 male NPT threaded pipe ends.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or gas technician depending on the service medium. Shut off supply pressure and depressurize the line completely before threading on the cap. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before installation; do not over-tighten, as brass fittings can crack under excessive torque. Gas line installations must comply with applicable local codes and IFGC requirements.
