B K/mueller Inds(import) 511-364HC Galvanized Reducing Coupling

Product Description

The B K/MUELLER INDS(IMPORT) 511-364HC is a galvanized steel reducing coupling designed to connect pipes of two different diameters in threaded plumbing systems. It transitions from a 1-1/4 inch female thread on one end to a 3/4 inch female thread on the other, allowing a reduction in line size without additional fittings. The galvanized finish provides corrosion resistance for use in water supply, drain, and general-purpose piping. Licensed plumbers and pipefitters install this fitting in residential and light commercial applications where reducing couplings are required to meet layout specifications.

This fitting is suited for threaded galvanized pipe systems in residential and commercial plumbing, water distribution, and general mechanical piping. Typical install scenarios include branch line reductions, equipment connections, and service drops where pipe sizing changes from 1-1/4 inch to 3/4 inch. The package contains 5 couplings per unit, making it practical for multi-point installations or stocking service trucks.
