Dewalt 9r209765 O-ring 2.20x1.60mm Seal

Product Description

The DEWALT 9r209765 is a replacement O-ring measuring 2.20 millimeters in outer dimension by 1.60 millimeters in cross-section, designed to maintain fluid and air seals within DEWALT power tool assemblies. O-rings at this scale are precision sealing components used to prevent leakage between mating surfaces inside tool housings, pneumatic assemblies, and hydraulic or pressure-rated subassemblies. This part is installed by tool repair technicians and service professionals performing component-level repairs on DEWALT equipment. Correct sizing is critical for proper seating and sealing performance, making exact specification matching essential during any repair procedure.

This O-ring is intended for use in DEWALT power tool and accessory repairs where the original seal has worn, cracked, or deformed. Applications include pneumatic tools, rotary tool assemblies, and other DEWALT equipment requiring small-diameter sealing components at this size class. Service centers and field repair technicians working on DEWALT equipment will find this part suited for component-level rebuild work where OEM-spec dimensions are required.

Installation Notes

Tool repair technicians should power down and disconnect all energy sources from the tool before disassembly. Inspect the mating groove for debris, scoring, or deformation before installing the new O-ring. Avoid using sharp tools to seat the O-ring, as nicks or cuts will compromise the seal. Follow DEWALT service documentation for proper disassembly and reassembly procedures specific to the tool model being serviced.
