Value Collection 13074 Malleable Iron Reducing Coupling

Product Description

The VALUE COLLECTION 13074 is a malleable iron reducing coupling designed to connect pipes of different diameters in threaded piping systems. It transitions from a 1-inch pipe to a 3/4-inch pipe and is rated for 300 psi on liquid and gas service and 150 psi on steam service. The galvanized finish provides corrosion resistance in wet or humid environments. This Class 150 fitting meets standard requirements for threaded iron pipe fittings used in mechanical, plumbing, and light industrial piping systems. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians encounter these fittings in gas and hydronic systems regularly.

This reducing coupling is suited for residential and commercial piping applications where a diameter reduction is needed in a straight run of pipe. Common uses include gas distribution lines, water supply piping, and steam heating systems. The 1 x 3/4-inch sizing is one of the most frequently encountered reduction combinations in building mechanical systems. It is sold in a package quantity of five units, making it practical for service vans and small jobs requiring multiple fittings.

Compatibility

Designed as an OEM-style threaded replacement fitting for Class 150 malleable iron pipe systems using 1-inch and 3/4-inch NPT connections in gas, liquid, or steam service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC codes. Shut off gas or fluid supply and depressurize the line before removing or installing any threaded fitting. Apply appropriate thread sealant rated for the service medium — do not use standard pipe dope on oxygen or certain gas lines where manufacturer guidance specifies otherwise. Inspect threads for damage before assembly and hand-tighten before using a pipe wrench to avoid cross-threading.
