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.

Technical Specifications

  • Trade Size: 1/2-in x 3/4-in MHT
  • Stem Length: 12-in
  • Configuration: Frostfree
  • Packaging: 4 ea per case

Typical Applications

  • Exterior Hose Bibb Rough-In and Replacement
  • Residential Water Supply Branch Lines
  • Freeze-Prone Climate Installations
  • New Construction Exterior Wall Water Connections
  • Remodel and Retrofit Plumbing Projects

Why SharkBite?

SharkBite fittings are built to simplify rough-in plumbing by removing the need for crimping, gluing, or soldering on the jobsite, which helps plumbers and contractors move faster while reducing the chance of a failed joint. The 24636LF frostfree sillcock carries that same install-friendly approach into an exterior application where freeze protection and backflow prevention both matter. Choosing a SharkBite sillcock means a connection method that's consistent with the rest of a SharkBite-equipped rough-in system, simplifying both the initial install and any future service work.

SharkBite 24636LF – Frequently Asked Questions

1) Will the SharkBite 24636LF frostfree sillcock accept a standard garden hose?
Yes. The outlet is 3/4-inch MHT (male hose thread), which is the standard garden hose thread, so any standard hose, splitter, or hose-bibb vacuum breaker threads straight on. The supply side is 1/2-inch.
2) What is the difference between the two sizes of the SharkBite frostfree sillcock, 24631LF and 24636LF?
The difference is the supply-side size. Model 24636LF is the 1/2-inch version and 24631LF is the 3/4-inch version. Match it to the cold-water branch you are tying into; both carry the frostfree stem and the hose-thread outlet.
3) How deep a wall will a 12-inch frostfree sillcock cover?
The 24636LF has a 12-inch stem, which puts the shutoff seat roughly a foot inside the wall from the sillcock head. That is the common length for a standard framed exterior wall with sheathing and siding. On a thicker assembly (masonry veneer, deep insulated wall, or a chase) the seat can end up in or outside the insulated cavity, which defeats the freeze protection, so measure from the finished exterior face to the point where the stem can sit in heated space before you pick the length.
4) Do I need to solder or crimp to install the SharkBite 24636LF sillcock?
No. It connects without crimping, gluing, or soldering, so there is no torch work on an exterior wall and no cure time on a solvent joint. That also makes it workable in a finished wall or a tight rim-joist pocket where open flame is a problem.
5) Can I use a frostfree sillcock instead of winterizing a regular hose bibb every fall?
That is the point of the frostfree design. On a standard hose bibb the valve seat sits at the exterior face, so water stands in it and splits the body when it freezes. On the 24636LF the shutoff is at the inboard end of the 12-inch stem, inside the heated wall, and the stem drains out through the spout when the valve closes. For that to work the sillcock has to be pitched slightly down toward the outside and the hose has to be disconnected, otherwise water is trapped in the barrel and you are back to a freeze break.
6) Does this SharkBite frostfree sillcock have built-in backflow protection, or do I still need a vacuum breaker?
The 24636LF is built to guard against back pressure and contaminated water being drawn back into the main supply, keeping the potable line isolated from the hose side. Whether a separate hose-connection vacuum breaker is also required is a local code call for your jurisdiction and facility type.
7) Is the SharkBite 24636LF sold individually or by the case?
Packaging is 4 each per case, which is worth knowing if you are buying for a single replacement rather than a multi-unit rough-in or a property-wide fall replacement program.
8) Is this sillcock suitable for commercial buildings or only houses?
It is intended for rough-in and replacement work on residential and light commercial water lines, on the cold-water branch feeding an exterior wall hose connection. For heavy commercial or institutional wash-down service, specify a hydrant rated for that duty instead.
