Product Features at a Glance

Softouch Handle
The 550-series features the patented Softouch™ handle, which is clad in a UV and weather-resistant thermoplastic rubber (TPR), that assures easy operation with wet or gloved hands.

Integral Lockshield
Removing the handle on a T-550, or TM-550 sillcock reveals an integrated lockshield, which is compatible with our loose key (SKU 107-410), to protect against unauthorized use.

Oversized Sill Flange
An oversized sill flange increases stability and makes the valve easier to install, as the screw holes are easier to access with tools.

Pitched Sill Flange
The built-in 5° pitch ensures proper draining once the valve has been shut off.

Integrated Vacuum Breaker
The automatic vacuum interruption prevents back-siphonage, keeping the system safe from backflow during operation.
