Elring 717.720 Seal Ring Sealing Washer

The Elring 717.720 is a precision-manufactured seal ring designed to provide a reliable, leak-free seal in automotive fluid systems. Elring is a globally recognized OEM and aftermarket supplier known for high-quality gaskets, seals, and sealing components engineered to meet or exceed original equipment specifications.

Seal rings of this type are commonly used as sealing washers on oil drain plugs, banjo bolts, transmission drain plugs, and hydraulic fittings. They work by deforming slightly under torque to fill microscopic surface irregularities and create a pressure-tight seal, preventing oil, transmission fluid, or coolant from seeping past threaded connections.

Key Features:

• Manufactured by Elring, a trusted OEM-grade supplier of sealing components
• Engineered to meet original equipment material and dimensional specifications
• Provides a reliable crush-type seal to prevent fluid leaks
• Suitable for use in oil, transmission, and hydraulic fluid applications
• Direct OEM-quality replacement for worn or damaged seal rings

As a best practice, seal rings should be replaced each time the associated drain plug or banjo bolt is removed to ensure a proper seal and prevent fluid leaks.
