Gearwrench 445 Internal Retaining Ring Pliers

Product Description

The GEARWRENCH 445 is a set of internal retaining ring pliers designed for installing and removing internal snap rings in bores, housings, and assemblies. The pliers feature a steel body with double-dip handles and accept replaceable tips, making them a durable choice for repetitive ring service work. The handle design is engineered to reduce hand fatigue during extended use. At 8 inches in overall length, these pliers give technicians solid leverage without bulk. They conform to ASME B107.500 standards, making them appropriate for professional trade environments including automotive, industrial maintenance, and mechanical assembly.

These pliers are suited for residential and commercial maintenance applications where internal retaining rings are common, such as HVAC equipment assembly, pump and motor service, hydraulic cylinder work, and general mechanical repair. The maximum ring size capacity of 1.75 inches covers a broad range of bore diameters found in typical field and shop service situations. The four tip diameter options — 0.039, 0.047, 0.048, and 0.074 inches — allow the tool to be configured for different ring groove profiles without requiring multiple dedicated pliers.

Installation Notes

Internal retaining ring pliers are typically used by HVAC technicians, industrial mechanics, and equipment service professionals. Always relieve system pressure and de-energize equipment before disassembling components that contain retaining rings. Ensure the correct tip diameter is installed and seated securely before applying force to avoid tip breakage or ring deformation. Safety glasses are recommended when removing snap rings, as rings can release suddenly under tension.
