Knipex 4411J3 Internal Retaining Ring Pliers 8.75 in

Product Description

The KNIPEX 4411J3 is a straight-head internal retaining ring pliers designed for installing and removing internal snap rings in bores, housings, and machined assemblies. Built to DIN 5256 C standards, this tool features a steel body with plastic-grip handles and precision tips measuring 2.30 mm in diameter (0.090 inches). At 8.75 inches overall length, it gives technicians the reach and leverage needed for clean, controlled ring engagement without deforming the ring or the bore. Installed by mechanical technicians, HVAC service pros, and maintenance tradespeople working on motors, pumps, and gearboxes.

The 4411J3 is suited for service and assembly work on internal retaining rings found in residential and light commercial mechanical systems. Typical applications include motor bearing retention, shaft and housing assemblies, pump housings, and similar components where a straight-tip pliers provides direct access to the ring groove. The 0-degree straight tip angle allows straightforward axial engagement in accessible bore locations without requiring an angled approach.

Installation Notes

This tool is used by licensed mechanics, HVAC technicians, and maintenance tradespeople servicing rotating equipment and assemblies. Always de-energize and lock out equipment before accessing internal components. Ensure the tip diameter matches the ring's pin holes to prevent slippage or ring deformation during installation or removal. Inspect tips for wear before each use.
