Socket Wrench GEKO G01781 internal connection 3/8"–1", 1/2" drive

GEKO Socket Wrench G01781 is a combined 5-step socket wrench designed for internal radiator valve and backflow screw connections, covering sizes from 3/8" to 1" and suited for installing and removing short faucet extensions. The tool fits internal connections and works with a 1/2" drive.

Advantages

The wrench provides five commonly used sizes (3/8", 7/16", 1/2", 3/4", 1") in a single compact tool, reducing the need to carry multiple sockets. Its internal-connection design is intended for radiator valve and backflow screw work, and the 1/2" drive compatibility allows use with standard ratchets and extensions. The compact form factor facilitates access in tight spaces when installing or removing short faucet extensions.

How to use

Select the appropriate socket size by aligning the tool with the internal connection or backflow screw. Attach the wrench to a compatible 1/2" ratchet or extension.

Usage recommendations

Use with a 1/2" drive ratchet or extension and check that the selected size seats fully on the connection. Avoid excessive torque on delicate fittings and inspect the tool for wear before use.
