Frost-free sillcock valve

The Legend Valve 108-160A is a 3/4 x 12 T550 quarter-turn frost-free sillcock valve with male and female NPT connections. It is designed for outdoor water supply shut-off where freezing protection is required. The quarter-turn operation allows quick opening and closing. This part is supplied new.

Suitable for standard frost-free installations

This valve suits plumbing projects that call for a frost-free sillcock with 3/4-inch connections and a 12-inch insertion length. It is not intended for systems needing a different insertion depth, a non-frost-free design, or a connection size other than 3/4-inch NPT. Buyers who need a longer or shorter stem should verify the 12-inch specification before ordering.

12-inch insertion length defines fit

The single specification that determines whether this valve fits is the 12-inch insertion length marked in the model as T550. Confirm that the wall thickness and rough-in distance match this dimension. If the required insertion length differs, this valve will not install correctly.

Questions about this item

What pipe thread size must my supply line have to connect to the 3/4 inch MNPT inlet of this sillcock valve?

The valve inlet uses a 3/4 inch male NPT thread, so your supply line needs a matching 3/4 inch female NPT fitting for a direct connection.

Will the 1/4 turn handle operate smoothly if my existing plumbing has high mineral content?

The quarter-turn mechanism uses a T-550 ball valve design that resists seizing better than multi-turn stems, though periodic operation is still recommended in hard-water areas.

How can I verify the frost-free function is working after I install the 12 inch valve body?

Shut off the interior supply, open the sillcock handle, and confirm water drains completely from the 12 inch valve body through the spout, leaving the exposed section empty.
