Valve for frost-free outdoor supply

This Legend Valve sillcock provides a frost-free connection for outdoor water lines. The multi-turn design allows gradual flow control using a soft-touch handle. Brass construction suits potable water plumbing. Male NPT and sweat ends give two installation options.

Thermal behaviour and operating pressure

Brass body and stem handle typical residential water pressure without deformation. The frost-free shaft keeps the shut-off seat inside the heated envelope, preventing freeze damage during cold weather. No external power or moving parts beyond the stem are involved.

Replaces standard hose bibbs and older sillcocks

The 1/2" x 4" configuration fits common supply stub-outs where a longer frost-free reach is required. Builders upgrading from quarter-turn or non-frost-free models gain freeze protection and finer flow adjustment. Not suited for systems needing a backflow preventer integrated into the valve body.

  • Multi-turn mechanism allows precise water flow control

Questions about this item

How do I install the 1/2" MxS TM-550 Multi-Turn coupling and what step is often missed?

Thread the MNPT end into the fitting and sweat the other end to copper pipe; the step often missed is cleaning and fluxing both joint surfaces before heating.

What maintenance or replacement will the TM-550 coupling need over time?

The multi-turn stem packing may need tightening or replacement if a drip appears at the handle, and the brass seat should be checked for mineral build-up during seasonal shut-off.

What limit appears first on the TM-550 coupling under sustained use?

Repeated thermal cycling can harden the stem packing, causing the first noticeable leak at the handle rather than at the threaded or sweat connections.
