Fox External 0.375 W x 2.300 OD x 0.050 TH Dia. 2.310 Bore Ptfe Bronze Tongue Cut

This PTFE bronze seal, measuring 0.375 inches wide with a 2.300 inch outer diameter and a 0.050 inch wall thickness, is designed for a 2.310 inch bore. Its tongue cut design is a specific choice for certain shock absorber applications, helping to ensure a proper seal against contaminants and maintaining consistent damping performance. The PTFE bronze material is chosen for its low friction properties and durability in demanding suspension environments.

The construction of this seal is key to its function. The PTFE (polytetrafluoroethylene) component offers excellent chemical resistance and a low coefficient of friction, which means it moves smoothly within the shock body without excessive wear. Combined with the bronze, it creates a well-built seal that can withstand the pressures and movements inherent in suspension systems. This specific tongue cut is a detail that mechanics look for to ensure it seats correctly and prevents leaks, which is crucial for the longevity and performance of your shocks.
