Bk 103-053HN Brass Hose Bibb 1/2 in Mip X 3/4 in Male Hose Thread

Product Description

The BK 103-053HN is a quarter-turn brass hose bibb from the ProLine Quartermaster Series, designed for residential and light commercial plumbing applications where a reliable shutoff at an outdoor or utility faucet connection is required. It features a chrome-plated brass ball and PTFE seats, providing a full shutoff with a 90-degree handle turn. The unit is rated for a maximum working pressure of 125 psi and meets ANSI/NSF 61.9 requirements for drinking water system components. The 1/2 inch MIP inlet connects to standard threaded pipe, while the 3/4 inch male hose thread outlet accepts a standard garden hose fitting. Licensed plumbers and experienced tradespeople handle the typical installation.

The 103-053HN is suited for residential potable water systems, irrigation supply lines, utility sinks, and outdoor hose connections. The MIP inlet threads comply with ANSI B1.20.1, and the hose-end threads comply with ANSI B1.20.7, ensuring proper fit with standard pipe and hose fittings. The quarter-turn ball mechanism makes it a practical replacement for aging gate-style bibs where faster shutoff operation is preferred. It ships as a single unit and is intended for above-grade or in-wall rough plumbing where a threaded connection is already present.
