Matco-norca m-cb05 Black Steel Merchant Coupling 1 in

Product Description

The MATCO-NORCA m-cb05 is a 1-inch black steel merchant coupling designed for joining threaded pipe sections in a wide range of piping systems. Rated at 150 LB, this fitting provides a reliable, pressure-rated connection for plumbing, spraying equipment, and general pipe distribution applications. Manufactured to meet or exceed applicable ASTM, ANSI, and API standards, it delivers consistent dimensional accuracy and material integrity. Licensed plumbers and pipefitters install this type of coupling in both new construction and retrofit work where a full-engagement threaded connection between pipe ends is required.

This coupling is suited for residential and light commercial piping applications including water supply lines, spraying equipment assemblies, and general-purpose black iron piping systems. The 150 LB pressure rating makes it appropriate for low-to-medium pressure service. Merchant couplings in this product family are available in a range of diameters from 1/8 inches to 6 inches, and half coupling configurations are also available within the same line.

Key Features

Compatibility

Designed as an OEM-style replacement and standard-fit merchant coupling for 1-inch threaded black steel pipe systems rated at 150 LB service, consistent with general plumbing and spraying equipment piping configurations.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and ANSI standards. Shut off and depressurize the line fully before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to male threads before making up the joint. Do not over-tighten; use a pipe wrench to snug the fitting and achieve a leak-free connection without stressing the fitting body.
