Absolute CNC Products – Copper Exhaust Gasket (Y.S Engines)

Y.S. 91SRX / 96SRX / 120SRX Engines

Designed for high-performance nitro helicopter applications, the Absolute CNC Products Copper Exhaust Gasket provides a durable and reliable seal between the engine and exhaust header. Manufactured from annealed copper for excellent conformability and heat resistance, this gasket helps reduce exhaust leaks while maintaining consistent engine performance.

Unlike traditional paper-style gaskets, copper construction withstands extreme exhaust temperatures and repeated heat cycles commonly experienced in aggressive 3D flying and high-performance tuning environments.

Features

• Precision-cut annealed copper construction
• Excellent heat resistance and sealing properties
• Reusable when properly inspected and maintained
• Helps reduce exhaust leaks and oil residue around the header
• Compatible with Y.S. 91SRX, 96SRX, and 120SRX engines

Specifications

• Material: Annealed Copper
• Thickness: 0.010" (0.25mm)
• Compatibility: Y.S. 91SRX, 96SRX, 120SRX

Installation Notes

Ensure all mating surfaces are clean and free of debris before installation. The gasket may be installed dry or with a very light coating of gasket sealant if preferred. Avoid excessive sealant that could squeeze into the exhaust port.

Because annealed copper is soft and highly conformable, handle the gasket carefully during installation to avoid bending or deformation.
