VITON* SEALS

Cylinders may be equipped with seals of Viton (fluorocarbon rubber) to suit elevated temperature or fluid compatibility requirements when application conditions preclude use of standard materials.

Viton is recommended for use with:
• Pneumatic service

• Petroleum oils and fluids

• Selected phosphate ester fluids

• Halogenated hydrocarbons

• Silicone fluids

Viton is suitable for use at temperatures from -20o F to +400o F (-29o C to +204o C). This material will withstand intermittent use to +550o F, but is subject to substantial seal life reduction with prolonged exposure to temperatures above +400o F.
When this option is desired, indicate if use is to suit tem- perature or fluid compatibility requirements.

Style 5 Rod End (with studded thread) should not be used at temperatures over +250o F. Other standard rod end styles are not subject to this limitation.

CARBOXYLATED NITRILE SEALS
Carboxylated Nitrile (CN) Seals are available for use in high speed/high cycle applications for air or hydraulic service.

They are also suitable for use with water or water based fluids. CN Seals are recommended for:
• Pneumatic service

• High speed/high cycle applications

• Water/water based fluids to 210o F

• HWBF (high water base fluids)
