Cylinder Wrenches

Catalog no. 330-56869 has three openings on one end (1 1/16 in., 1 1/8 in. and 1 1/4 in.) for tightening valve connections and most commonly used gas connections. The opposite end has a 3/8 in. square box for opening cylinder valves that do not have hand wheels. Catalog no. 330-56872 is a basic 3/8 in. square for opening cylinder valves that do not have hand wheels, such as chlorine and hydrogen sulfide. The special configuration of catalog no. 330-56875 provides an easy method of opening extra tight hand-wheel operated cylinder valves and for removing difficult cylinder caps.
