Bk Llc 108-553HN Brass Quarter Turn Flanged Sillcock

Product Description

The BK LLC 108-553HN is a brass quarter-turn flanged sillcock designed for residential and light commercial outdoor water supply applications. The sillcock features a chrome-plated brass ball and a patented body and handle assembly that allows full open or full close operation with a single 90-degree turn. It is low-lead compliant and rated for a maximum working pressure of 125 psi. The 1/2 inch inlet connects to standard supply lines, and the hose outlet accepts any standard 3/4 inch garden hose or washing machine hose fitting. Licensed plumbers install this fitting as part of exterior wall rough-in or hose bib replacement work.

This sillcock is suited for exterior wall installations in residential homes and light commercial buildings. It is commonly installed through a rim joist or exterior wall where a flanged face plate is needed for a clean finished appearance. The quarter-turn ball design simplifies seasonal shutoff and reduces maintenance compared to traditional compression-style sillcocks. The 3/4 inch hose thread outlet makes it compatible with standard garden hoses and washing machine supply connections without adapters.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC.
