1/4 Turn No Lead Frostfree Sillcock Valve

This 3/4 x 12 T-550NL sillcock valve provides a quarter-turn shut-off for outdoor water supply lines. The no-lead construction meets California Proposition 65 requirements for reduced lead content. It is intended for residential and light-commercial irrigation or hose-bibb installations where freeze protection is required. The MNPT and FNPT connections allow direct threading to standard pipe fittings.

Installation checks for the T-550NL sillcock

Verify that the existing supply line uses a compatible 3/4-inch thread type before ordering. Confirm the wall thickness allows the 12-inch insertion depth so the valve seat remains inside the heated space. Ensure local plumbing codes accept a quarter-turn mechanism for frost-free sillcocks. The product carries a Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Sustained load behavior of the frost-free valve

During extended seasonal use the quarter-turn ball mechanism maintains consistent flow without the gradual stiffening common in multi-turn stem designs. The no-lead brass body resists dezincification when water sits in the valve for long periods between irrigation cycles. Frost-free performance depends on the valve being installed with a downward pitch so residual water drains completely after each shut-off.

Questions about this item

Does the 108-160NL sillcock include any fittings or pipe tape, or must those be purchased separately?

The valve ships as a single 3/4 x 12 T-550NL quarter-turn frost-free sillcock with male and female NPT threads; pipe tape, adapters or mounting hardware are not included and must be sourced separately.

How do I choose between the 108-160NL and other Legend Valve frost-free sillcocks?

Select the 108-160NL when you need a 3/4-inch connection with a 12-inch insertion length, quarter-turn operation and no-lead brass construction; other models differ in inlet size, stem length or handle style.

What does the 12-inch figure mean once the 108-160NL is installed through the wall?

The 12-inch dimension is the overall insertion length from the exterior flange to the interior shut-off seat, so the valve seat sits that far inside the heated space to prevent freezing.
