Internal 10-10 Seal

The Internal 10-10 Seal from Diversified Machine is a precision lower shaft coupler seal engineered for quick-change tool systems and high-performance drivetrain applications. This component serves as the critical sealing interface in mechanical assemblies where shaft rotation and pressure containment demand reliability. Mechanics and automotive enthusiasts working with DMI quick-change systems will recognize this seal as essential maintenance inventory—preventing fluid loss, contamination ingress, and premature bearing wear in demanding shop and racing environments.

Constructed from a durable rubber-to-steel composite design, the Internal 10-10 Seal employs a dual-durometer elastomer matrix bonded to a precision steel case. This hybrid construction provides superior resistance to thermal cycling and fluid exposure while maintaining consistent contact pressure against rotating shafts. The 10-10 designation indicates dual-seal geometry optimized for bidirectional sealing, ensuring performance across variable operating conditions. At just 0.08 lbs and measuring 3.25 x 0.85 x 3.65 inches, this compact seal integrates seamlessly into OEM and aftermarket quick-change assemblies without adding bulk or weight penalty.

Technicians maintaining DMI quick-change systems will benefit from stocking this replacement seal for routine service intervals or emergency field repairs. Whether you're operating a professional machine shop, performance automotive facility, or serious home garage, this seal prevents catastrophic fluid loss that could damage expensive downstream components. Installation is straightforward for anyone familiar with coupler disassembly; the seal seats directly into the lower shaft cavity. Carrying spare Internal 10-10 Seals ensures minimal downtime when drivetrain maintenance becomes necessary, making this a cost-effective preventative measure for any operation relying on quick-change technology.
