Teflon Input Shaft Rings Powerglide

The Teflon Input Shaft Rings Powerglide by COAN is a precision transmission seal component engineered for serious transmission builders and automotive mechanics upgrading or rebuilding Powerglide automatic transmissions. These PTFE (polytetrafluoroethylene) input shaft rings are critical wear items that prevent fluid leakage and maintain internal pressure integrity during high-performance driving, drag racing, or heavy-duty applications. Whether you're performing a transmission overhaul or sourcing OEM-equivalent replacement seals, these rings deliver the durability and chemical resistance that modern transmission fluid demands.

Teflon (PTFE) is the gold standard for transmission sealing because it exhibits exceptional low-friction properties, resists thermal degradation up to sustained high temperatures, and remains stable across all conventional transmission fluids including synthetic formulations. Unlike elastomer seals that swell or degrade over time, PTFE rings maintain dimensional stability and provide a consistent seal surface against input shaft journals. The pair configuration ensures complete sealing coverage across both critical contact points, preventing pressurized fluid from migrating past the shaft and into the bell housing or pan. COAN's manufacturing precision guarantees tight tolerances that match original equipment specifications, making these rings a direct fit for stock or modified Powerglide assemblies.

Powerglide builders, restoration shops, and drag racing teams rely on quality input shaft rings to prevent leaks that compromise shift consistency and cause fluid loss under hard acceleration or prolonged boost. Installation requires transmission disassembly and careful seating on the input shaft during reassembly—a task well within reach of any mechanic experienced with transmission teardown. These rings are essential whether you're rebuilding a stock unit, upgrading internals, or servicing a transmission that has logged thousands of miles of street or track duty.
