Merit Brass XNL111-08 1/2 Inch Fnpt Brass Pipe Coupling

Product Description

The MERIT BRASS XNL111-08 is a straight pipe coupling designed to join two sections of pipe in a continuous run without changing direction. Rated at 125 lb, it features female NPT (FNPT) threads on both ends in a 1/2 inch nominal pipe size. The fitting is machined from brass and carries a rough finish, making it suitable for general-purpose plumbing, compressed air, and fluid distribution systems. Licensed plumbers and pipefitters are the typical installers, though the fitting is also common in industrial maintenance applications.

This coupling fits standard 1/2 inch nominal pipe threads and is suited for residential and light commercial plumbing, HVAC condensate lines, and compressed air distribution. The 125 lb pressure rating makes it appropriate for low- to medium-pressure service. Its brass construction provides corrosion resistance in water service and compatibility with a wide range of fluid media.

Key Features

• Straight through-flow design joins two pipe sections in a continuous run
• FNPT threads on both ends accept standard tapered male pipe threads
• 125 lb pressure rating suitable for low- to medium-pressure applications
• Brass construction offers corrosion resistance and durability in water and fluid service
• Rough finish provides a clean surface ready for wrench installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch nominal NPT pipe systems in plumbing, HVAC, and compressed air applications.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or local plumbing code requirements. Shut off and depressurize the supply line completely before disassembling any fitting. Apply PTFE tape or approved pipe thread sealant to the male threads before assembly. Do not overtighten brass fittings, as the material is susceptible to thread damage from excessive torque.
