R35

High-pressure, low-speed external rotary/swivel seal

Small footprint external seal designed for rotary couplings/distributors.

The one-piece elastomer design makes it easier to fit in multi-port units than traditional PTFE-based seals. This seal is made of a high-performance wear-resistant elastomer designed to separate two different media. This seal handles up to 5,000*psi. Small quantities are available in 1 to 3 days.

R67

Low-friction, no stick-slip external swivel seal for medium to high pressure

Composite seal for sealing the bore of swivel joints and rotary couplings.

The design is an O-ring energizing a wear-resistant PTFE cap. The cap has oil grooves on the outer diameter to provide lubrication, while the contoured inside diameter of the cap fits with the O-ring to prevent spinning between the cap and the O-ring. It is used for pressure up to 5000*psi. The seal can operate under very high PV for short operating cycles. Small quantities are available in 1 to 3 days.

R6VA

Light duty V-ring

Light-duty dirt-exclusion seal.

The seal is stretched onto the shaft and rotates with the shaft and seals axially against the bearing side wall, housing, washer or even the heel of the pressure seal. The flexible sealing lip applies a light axial force that reduces as the shaft RPM increases, leading to very low friction and heat. Low contact force allows the seal to accommodate coaxial misalignment or runout. Small quantities are available in 1 to 3 days.

Operating Range

Material	Continuous Pressure	Temperature	Surface Speed
N101	No Pressure	-13 to 212°F (-25 to 100°C)	Up to 1,800 fpm (9m/s)
