Abstract: A valve wrench comprising a wrench for valves having a hand wheel operator, combined with the elongated handle of an adjustable wrench to supply the leverage required. The valve wrench has an elongated body having an elongated, slightly tapered seat portion corresponding to the slightly tapered end portion of the handle of an ordinary adjustable wrench to receive such end portion of the handle therein. The corresponding tapered configuration keeps the valve wrench from slipping off the end of the adjustable wrench. A screw and washer extend through an aperture in the end of the adjustable wrench handle to clamp the bottom wall of the valve wrench securely against the facing wall of the adjustable wrench handle. The screw and washer may be replaced by a valve wrench that is integrally formed with an adjustable wrench. The working end of the valve wrench has speced apart inner and outer jaw members which define a jaw recess to snugly receive the rim of the hand operator of the valve.
