Product Identity

The Legend Valve 108-003A is a 1/2 inch by 8 inch brass quarter-turn frost-free sillcock with a PEX inlet. It serves as a replacement component for outdoor bath faucet assemblies requiring freeze protection.

Who It Suits

This part fits installations needing a PEX connection and a 108 style valve body. Buyers who need a different connection type, a non-frost-free design, or a different overall length should look at other options.

Accessory Impact

The product ships as a single valve unit without additional fittings or tools. Installers must supply their own PEX crimp rings, expansion sleeves or compatible connectors to complete the connection.

Questions about this item

What PEX tubing size and connection type does the 1/2 x 8 T550P sillcock require for installation?

The sillcock uses a 1/2 inch PEX inlet connection, so you need compatible 1/2 inch PEX tubing and the appropriate crimp or expansion fittings for a watertight joint.

Will the 1/4 turn frostfree valve operate correctly with older 1/2 inch copper supply lines if I use a transition fitting?

Yes, a standard 1/2 inch PEX-to-copper transition fitting lets the T550P connect to existing copper pipe while maintaining the quarter-turn action and frost-free drain function.

How can I verify the frost-free drain is working after I install the sillcock?

Shut off the interior supply, open the 1/4 turn handle fully, and confirm water drains completely from the spout; no residual flow means the frost-free mechanism is seating properly.
