1/2" PEX Frostfree Sillcock

The Legend Valve 108-003NL is a 1/2 inch by 8 inch T-550P no-lead brass quarter-turn frostfree sillcock with a PEX inlet. It provides an outdoor water connection designed to resist freezing in cold weather. The quarter-turn mechanism allows quick on and off operation for garden hoses or irrigation systems. This fitting suits residential and light commercial plumbing installations requiring a durable hose bibb.

Push-fit PEX installation steps

The PEX inlet accepts a push-fit or crimp connection without soldering, making it faster to fit than threaded copper alternatives. Ensure the tubing is cut square and fully seated to the stop; an incomplete insertion is the most common cause of leaks. The no-lead brass body complies with California Proposition 65 requirements but contains a chemical known to the state to cause cancer and reproductive harm. Use compatible PEX tubing and verify local code acceptance before installing.

Freeze protection under sustained cold

The extended 8 inch shaft places the valve seat inside the heated wall cavity so water drains from the exposed portion when closed. During prolonged sub-zero periods the quarter-turn ball valve maintains a positive seal without the packing wear that affects multi-turn stems. The brass construction resists corrosion from mineral-rich water better than plain steel bibbs. The frostfree design only works if the hose is disconnected so water can drain completely.

Questions about this item

How do I verify the 1/4 turn handle operates the valve correctly after installation?

Turn the handle a full quarter rotation and confirm water flows freely; turn back to the stop and ensure flow ceases completely with no drip.

What components are included with the 108-003NL sillcock and what must be sourced separately?

The brass sillcock with PEX inlet is supplied; PEX tubing, crimp rings, a crimp tool and any mounting hardware are not included.

Which version of the T-550P frost-free sillcock should I select for a standard half-inch PEX supply line?

Choose the 1/2 x 8 T-550P NL model listed; it matches a half-inch PEX inlet and provides the eight-inch frost-free insertion length.
