Bk 108-034HC Cast Iron Sillcock 3/4 Inch

Product Description

The BK 108-034HC is a 3/4-inch cast iron sillcock designed for outdoor water supply connections to hose bibs and lawn irrigation applications. Built with a brass body and a 6-point cast iron handle, this loose-key lawn faucet offers heavy-duty construction suited for residential and light commercial service. The oversized notched flange provides a stable, secure mount against exterior walls or framing. The faucet is certified to NSF 61, confirming compliance with standards for potable water contact materials. Plumbers and general contractors install this type of fitting as a primary exterior water shutoff and hose connection point.

This sillcock is suited for exterior wall installations in residential homes, multifamily buildings, and light commercial structures. It is typically installed through rim joist or masonry wall penetrations where a stable flange mount is needed. The loose-key design limits unauthorized use, making it practical for commercial storefronts, irrigation risers, and any application where controlled access to the water supply is required.

Installation Notes

Installation is performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the main water supply and relieve line pressure before cutting into or connecting to the supply line. Seal all threaded connections with PTFE tape or pipe joint compound rated for potable water service. Ensure the faucet is pitched slightly toward the exterior to promote drainage and reduce freeze risk in cold climates.
