Dewalt 851753 O-ring 2.734 X 0.139 Inches

Product Description

The DEWALT 851753 is a replacement O-ring designed for use in DEWALT power tools and accessories. This O-ring measures 2.734 inches in inner diameter with a cross-section of 0.139 inches, providing a precise sealing fit for the specific tool cavity it services. O-rings of this type create a leak-proof barrier between mating components, preventing fluid or air loss that could compromise tool performance. Installation is typically performed by licensed technicians or experienced service professionals during routine maintenance or repair procedures.

This O-ring is a direct OEM-style replacement intended for DEWALT power tool applications requiring this specific dimensional profile. It is commonly replaced during seal kit service intervals, after visible wear or deformation is found on inspection, or when a tool exhibits pressure loss or fluid leakage. Proper fitment depends on matching both the inner diameter and cross-section to the original specification.

Installation Notes

Power down and disconnect the tool from any power source before beginning disassembly. Remove the worn O-ring carefully to avoid scoring the seating groove, then clean the groove before installing the replacement. Apply a compatible lubricant to the new O-ring before seating it to prevent tearing during reassembly. Follow the tool manufacturer's service documentation for proper reassembly sequence.
