Dual-size hex key adapter that fits 3/16″ and 5/16″ service valve stems — the two most common sizes on residential and light commercial AC systems. Saves you from digging through a hex key set every time you need to open a service port. Compact enough to keep on your gauge hose set.

Specs: 3/16″ and 5/16″ hex sizes, by Hilmor

Replaces: 1839046

Fits: Standard refrigeration service valves on AC condensers and heat pumps
