Merit Brass XB111-16 Brass Pipe Coupling 1 in Class 125

Product Description

The MERIT BRASS XB111-16 is a Class 125 brass pipe coupling with female British standard pipe taper (FBSPT) connections on both ends. It is designed to join two sections of pipe in a straight run, providing a secure, leak-resistant joint in low-to-moderate pressure piping systems. The 1-inch fitting size suits common residential and light commercial plumbing lines. Licensed plumbers and pipefitters install this coupling during new construction, system repairs, and retrofits where a reliable threaded brass connection is required.

This coupling is suited for use in residential and light commercial plumbing, HVAC hydronic piping, and general-purpose fluid handling systems. The FBSPT x FBSPT end configuration allows threaded assembly without additional adapters when mating to compatible female-threaded pipe ends. Its Class 125 pressure rating makes it appropriate for water supply, low-pressure steam, and general service piping applications.

Key Features

• Class 125 pressure rating for water supply and low-pressure service lines
• FBSPT x FBSPT end connections for straightforward threaded assembly
• 1-inch fitting size fits standard pipe sizes common in residential and light commercial systems

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off water supply and depressurize the line before beginning work. Apply thread sealant tape or pipe compound to the male threads before making up the joint. Do not overtighten, as brass fittings can crack under excessive torque.
