Dewalt 87112 O-ring 0.924 X 0.103 Inches

Product Description

The DEWALT 87112 is a replacement O-ring sized at 0.924 inches inner diameter by 0.103 inches cross-section. O-rings of this type create a reliable pressure seal within pneumatic and hydraulic tool assemblies, preventing air or fluid leakage at joints, pistons, and valve seats. This part is installed during routine maintenance or repair of DEWALT power tool and pneumatic equipment. Keeping the correct O-ring size on hand reduces equipment downtime and restores factory sealing performance.

This O-ring is intended for use in DEWALT tools and equipment that rely on sealed pneumatic or hydraulic circuits. It is most commonly replaced during scheduled maintenance, after visible wear or cracking is observed, or when a tool develops an air or fluid leak. Technicians and service professionals performing field or shop repairs on DEWALT equipment will find this part necessary for a complete, proper rebuild.
