Type CR Rod Seal

Service Description: Economical TFE and or Engineering Plastics wear cap with O-Ring for use in dynamic sealing situations where minimum friction is essential or wear environment is too severe for elastomers.

For piston, rod, and slow rotating applications.

N= NFPA Standard Fractional Radial Compression Piston Ring glands.

Special sizes consult Seal Science Engineering.

(See Seal Science gland charts for dimensions.)

Special Options: Friction-Reducing grooves, pressure balancing features, and blow-by- preventing notches can be added. Call 1-800-576-SEAL for assistance.
