Knipex 49 41 A01 External Retaining Ring Pliers

Product Description

The KNIPEX 49 41 A01 is a fixed-tip external retaining ring pliers designed for installing and removing external snap rings in the 1/8 to 25/64 inch diameter range. The tool features a 90-degree angle head, placing the 0.90 mm tips perpendicular to the handle for access in confined or awkward installation points. Overall length is approximately 5.12 inches (130 mm). The steel body and non-slip plastic-coated handles give technicians a secure, controlled grip during repetitive ring placement. A built-in spring keeps the tips open between actuations, reducing hand fatigue. This pliers is used by HVAC technicians, machinists, plumbers, and general trade mechanics wherever external circlips need to be seated or pulled.

The 49 41 A01 suits applications requiring external ring service on small-diameter shafts and bores in the 1/8 to 25/64 inch range. The 90-degree angle head is well-suited for components recessed inside housings, motor assemblies, or valve bodies where a straight-tip tool cannot reach the ring groove cleanly. The included limiter feature controls tip spread, preventing over-expansion of the ring during installation. This tool is packaged and sold individually.

Installation Notes

This tool is used by licensed mechanics, HVAC technicians, and plumbers servicing components that use external snap rings. Always de-energize equipment and relieve any system pressure before removing or installing retaining rings on rotating or pressurized assemblies. Use the limiter to set maximum tip spread before engaging the ring to avoid distorting or launching the circlip during removal. Eye protection is recommended any time retaining rings are being seated or extracted.
