Description

A quality gasket material is foundational to any reliable engine or powersports build—it’s the seal between catastrophic leaks and a tight, performing system. The HELIX 403-5012 delivers consistent, durable sealing across oil, fuel, coolant, and exhaust applications, so you can focus on performance rather than troubleshooting leaks. With a proven aramid-fiber composite construction and temperature resistance to 750°F, this material handles the thermal cycling and chemical exposure that racing and high-performance engines demand.
