Williams Comfort Products HKT-5/16 Arm T-key

Product Description

The WILLIAMS COMFORT PRODUCTS HKT-5/16 is a 5/16-inch by 6-inch arm T-key designed for use in heating appliance service and installation. This manual valve key provides the leverage needed to operate gas valves and similar fittings that require a T-handle interface. It is a hand tool kept in a service technician's kit for fieldwork on heating systems. The compact form factor and standard 5/16-inch drive size make it a practical fit for common service tasks. HVAC technicians and gas appliance service pros typically carry this type of key as part of routine service equipment.

This T-key is suited for residential and light commercial heating service applications where a 5/16-inch T-handle tool is required. It is commonly used when accessing or adjusting components on floor furnaces, wall heaters, and similar gas heating appliances during installation, startup, or maintenance calls. The 6-inch arm length provides adequate torque without requiring additional leverage tools in standard service scenarios.

Installation Notes

This tool is used by qualified HVAC technicians and gas appliance service professionals during heating system service calls. Always shut off the gas supply at the main shutoff valve before performing any work on gas fittings or valves. Follow local codes and manufacturer service procedures when operating valve components. Do not apply excessive force beyond what the arm length naturally provides, as overtorquing valve stems can cause damage or leaks.
