Lowell valve key sockets can grip worn and corroded nuts
July 2, 2013 – Lowell’s valve key sockets come in a durable, compact case containing three different sizes that can handle anything from standard 2 in. square nuts on down to 1 13/16-in. Boston gate nuts. The kit also includes an attachment plate and a 3-in. screw for mounting the socket on any standard key. The company says its valve key sockets are the solution for users who need to open a valve when the key cannot engage a badly worn or corroded nut. Lowell’s valve key sockets are guaranteed against defects in material and workmanship for one year from date of delivery.
