The WILLIAMS COMFORT PRODUCTS 13557 is a replacement hook jaw designed for 36-inch pipe wrenches. This component restores full gripping function to a worn or damaged pipe wrench, allowing tradespeople to return a tool to service rather than replace it entirely. The hook jaw interfaces with the wrench body and heel jaw to deliver the clamping force required for rotating large-diameter pipe. At 4.118 pounds, this is a substantial forged-style replacement part suited for heavy-duty plumbing and pipefitting applications.
This replacement hook jaw is intended for professional plumbers, pipefitters, and mechanical contractors working on commercial or industrial piping systems where 36-inch pipe wrenches are standard. It is sold as a single unit and is appropriate for any shop or field operation that maintains a fleet of large pipe wrenches as part of routine tool upkeep.
Designed as an OEM-style replacement hook jaw for 36-inch pipe wrenches. Verify fitment against your specific wrench model before installation.
Installation is typically performed by a licensed plumber or pipefitter during routine tool maintenance. Before replacing the hook jaw, ensure the wrench is disassembled according to standard manufacturer procedure and the adjustment nut is fully removed. Inspect the heel jaw and adjustment mechanism for wear before reinstalling with the new hook jaw. Follow shop safety practices when handling heavy wrench components.
