Merit Brass XNL112-4032 Reducer Coupling 2.5x2 in Fnpt Brass

Product Description

The MERIT BRASS XNL112-4032 is a threaded reducer coupling used to connect pipe sections of two different diameters in plumbing, mechanical, and industrial piping systems. Sized at 2-1/2 x 2 inches nominal with female NPT (FNPT) threads on both ends, it provides a secure, leak-resistant transition between pipe sizes. Rated at 125 lb pressure class, this fitting is manufactured from brass with a rough finish. It is installed by licensed plumbers and pipefitters in applications requiring a reliable, corrosion-resistant threaded connection.

This reducer coupling suits residential and commercial plumbing systems where a step-down transition between 2-1/2 inch and 2 inch nominal pipe is required. Common applications include water supply lines, hydronic heating systems, compressed air distribution, and light industrial fluid handling. The FNPT thread pattern mates with standard male NPT pipe threads, making it compatible with widely available pipe stock and fittings.

Key Features

• 2-1/2 x 2 inch nominal size provides a direct step-down pipe transition
• Female NPT (FNPT) threads on both ends for standard threaded connections
• 125 lb pressure class rating suitable for plumbing and mechanical service
• Brass construction offers corrosion resistance and durability in fluid systems
• Rough finish suitable for use with thread sealant tape or pipe dope

Compatibility

Designed as an OEM-style threaded reducer fitting compatible with standard NPT male-threaded pipe and fittings in 2-1/2 inch and 2 inch nominal sizes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and IPC requirements. Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant, such as PTFE tape or pipe dope rated for the service fluid, to the male threads before assembly. Do not overtighten, as brass fittings can crack under excessive torque.
