S&S Cycle 50-8045 Nitrile Transmission Quad Seal O-Ring

The S&S Cycle 50-8045 is a precision-engineered nitrile rubber quad seal O-ring designed specifically for Harley-Davidson motorcycle transmissions. This seal features an X-shaped cross-section profile that provides superior sealing performance compared to traditional round O-rings.

Key Features:

• Nitrile rubber construction for excellent oil and fuel resistance
• Quad seal (X-ring) design with four sealing surfaces for enhanced reliability
• Measures 1.734 inches x 1.875 inches
• Engineered for transmission ball bearing applications
• Reduces friction and wear compared to standard O-rings
• Manufactured by S&S Cycle to OEM quality standards

Quad seal O-rings offer distinct advantages over conventional O-rings in dynamic applications. The four-lobed cross-section creates dual sealing points on both the top and bottom surfaces, providing improved sealing capability while reducing rolling friction. The nitrile material delivers excellent resistance to petroleum-based oils, transmission fluids, and the temperature extremes encountered in motorcycle transmissions.
