SharkBite 24636LF Frostfree Sillcock, 1/2-in x 3/4-in MHT x 12-in

SharkBite 24636LF Frostfree Sillcock, 1/2-in x 3/4-in MHT x 12-in

The SharkBite 24636LF is a frostfree sillcock designed for outdoor hose bibb rough-in where freeze protection is a priority. Sized 1/2-in x 3/4-in MHT with a 12-in stem length, this sillcock is built to protect the valve body from freezing conditions while also guarding against back pressure and contaminated water flowing back into the main supply line. It installs on the cold-water branch feeding an exterior wall hose connection and is intended for plumbers and contractors handling rough-in and replacement work on residential and light commercial water lines.

Key Features

• Trade Size: 1/2-in x 3/4-in MHT connection sized for standard supply branch lines and garden hose thread outlets.
• Stem Length: 12-in frostfree stem positions the shutoff valve inside the heated wall cavity, away from the exterior sillcock head, to reduce freeze exposure.
• Backflow Protection: Protects against back pressure and contaminated water being drawn back into the main line, keeping the potable supply isolated from the hose-side connection.
• No Special Tools Required: Installs without crimping, gluing, or soldering, allowing a straightforward connection to existing supply piping.
• Faster Installation: The connection method reduces install time on the jobsite and lowers the risk of installation errors compared to solvent-weld or solder joints.
• Configuration: Frostfree design intended for exterior hose bibb applications subject to seasonal freezing conditions.
