Replacement Hook Jaw for 18 Inch Wrench

This Westward 31D046 replacement hook jaw fits an 18 inch pipe wrench. It is made from alloy steel with a serrated texture for gripping pipe. The part is compatible with Grainger part numbers 4YR93A, 4YR90B, 39CG47 and 39CG50. It is sold new as a direct replacement component.

For Pipe Wrench Maintenance and Repair

This jaw suits technicians and tradespeople who need to restore an 18 inch Westward pipe wrench to working condition. It is not for users who require a complete wrench assembly or a different jaw size. Buyers looking for smooth-faced jaws or alternative materials should look at something else.

Alloy Steel Serrated Jaw Material

The single specification that decides fit is the alloy steel serrated jaw material. This construction determines the grip profile and durability on pipe surfaces. Confirm the existing wrench uses a serrated alloy steel hook jaw before ordering.
