The B&K 104-412 Frost-Free Sillcock from the ProLine Series is engineered to provide reliable outdoor water access in regions prone to freezing temperatures. Unlike standard hose bibbs, this frost-free design ensures that water drains from the valve body when shut off, preventing freeze-related damage.

Constructed from chrome-plated brass, the sillcock offers superior corrosion resistance and long-lasting durability. It features a 3/4-inch male pipe thread (MIP) inlet and a 3/4-inch male hose thread (MHT) outlet, making it compatible with standard plumbing and garden hose connections. The heavy-duty six-point cast-iron handle allows for easy operation, even in cold weather.

The valve includes a notched flange for secure mounting to siding and is NSF 61 compliant for potable water use. It also supports dual connection inlets—threaded (ANSI B1.20.1) and solder (ANSI B16.18)—for flexible installation options.
