Abstract
An adjustable wrench particularly useful to facilitate ease of installation and removal of fluid fittings in and from a fluid system. The wrench includes an elongated handle threadedly cooperating with a body member. The body member has a pair of opposed clamping faces defining a clamping cavity adapted to receive an associated fitting. Relative rotation between the handle and body portion axially advances and retracts a smooth end face of the handle into and out of abutting engagement with a side wall of the fitting. A cutout region in the wrench body is adapted to receive one branch of an associated tee or cross type fluid fitting. The subject wrench readily facilitates clamping engagement of a fitting while coupling nuts are run up on or backed off of the fitting branches by conventional means.
