Dewalt 101236 O-ring 2.50 X 0.445 Inches

Product Description

The DEWALT 101236 is a replacement O-ring designed to maintain a pressure-tight seal in DEWALT power tools and equipment. O-rings of this type seat in a machined groove and compress against mating surfaces to prevent fluid or air leakage under operating pressure. This part measures 2.50 inches in inner diameter with a cross-section of 0.445 inches. It is typically installed by service technicians performing maintenance or rebuild work on pneumatic or hydraulic tool assemblies where the original seal has worn, cracked, or lost its elasticity.

This O-ring is suited for service and rebuild applications on DEWALT tools and equipment that rely on elastomeric seals for pressure retention. It is a direct OEM replacement part, making it appropriate for restoring equipment to factory sealing performance. Service technicians and repair shops stocking common seal sizes will find this part relevant for maintaining pneumatic or pressurized tool systems.

Key Features

• OEM replacement O-ring engineered to DEWALT dimensional specifications
• Inner diameter of 2.50 inches for precise groove fitment
• Cross-section of 0.445 inches for proper compression and seal integrity
• Designed to restore pressure-tight performance in worn or degraded seal applications

Compatibility

Designed as an OEM-style replacement O-ring for DEWALT power tools and equipment requiring a 2.50 x 0.445 inch seal.

Installation Notes

Installation should be performed by a qualified service technician. Always depressurize and power down the tool completely before disassembling any seal housing. Lubricate the O-ring lightly with a compatible grease before seating it in the groove to prevent tearing during assembly. Take care not to nick or stretch the ring during installation, as damage to the seal will result in leakage under pressure.
