The WILLIAMS COMFORT PRODUCTS 13574 is a replacement knurl nut designed for 14-inch pipe wrenches. The knurl nut is the threaded adjustment component that controls jaw tension and allows the wrench to be sized to different pipe diameters. When the original nut strips, cracks, or seizes, replacing it restores full tool function without the cost of a new wrench. This part is sold individually and suits maintenance-focused tradespeople who prefer to rebuild tools rather than replace them outright.
This replacement knurl nut fits Williams 14-inch pipe wrenches and is suited for plumbing, pipefitting, and mechanical service environments where pipe wrenches see heavy daily use. It is a direct-fit component intended for field or shop-level tool maintenance. Technicians working in industrial, commercial, or residential plumbing applications will find this a practical stock item to keep on hand.
Designed as a replacement knurl nut for Williams 14-inch pipe wrenches. Refer to your tool documentation or contact the manufacturer to confirm fitment with your specific wrench model before ordering.
Installation is typically performed by a plumber, pipefitter, or maintenance technician using basic hand tools. Before servicing the wrench, ensure it is clear of any pressurized or energized systems. Remove the existing damaged knurl nut, clean the heel jaw threads, and thread the replacement nut onto the adjustment screw until properly seated. Inspect jaw alignment and tension after installation before returning the tool to service.
