Legend Valve 108-159A Frostfree Sillcock

This frostfree sillcock valve is designed for outdoor water supply connections where freeze protection is required. The quarter-turn operation allows quick shutoff with minimal effort. It suits homeowners and plumbers installing or replacing a hose bibb on an exterior wall.

Quarter-turn mechanism under sustained use

The 1/4 turn handle provides reliable operation over repeated cycles without the packing wear common in multi-turn designs. Frostfree construction keeps the shutoff seat inside the heated space, preventing ice formation during extended cold periods. MNPT and FNPT threads ensure a secure joint that resists leakage under continuous pressure.

Replaces worn multi-turn hose bibbs

This valve upgrades older sillcocks that require multiple rotations to close and are prone to stem packing leaks. The jump is worth it when the existing valve drips at the handle or fails to shut off completely. It also replaces frostfree units with damaged seats or split casings caused by trapped water. Buyers needing a non-frostfree valve for interior use should select a different model.

Questions about this item

How loud does the 108-159A valve get when water runs through it all day?

The 108-159A is a quarter-turn frost-free sillcock with no moving parts that generate noise; normal flow sounds are the only sound you will hear.

What piping must already be in place for the 3/4 x 10 T-550 connections?

You need a 3/4-inch male NPT supply line and a 3/4-inch female NPT outlet already installed to thread the valve directly.

Will the 108-159A thread onto older 3/4-inch NPT plumbing without adapters?

Yes, both the inlet and outlet use standard 3/4-inch NPT threads, so it mates with existing NPT fittings of the same size.
