EngiSeal RF6

Movement

Rotary

Speed

25 ft/s

Action

Single

Description:

The RF6 is a rotary flanged seal. The flanged heel helps to prevent rotation of the sealing element by being clamped down within the groove. It is an extremely low friction seal and performs very well in high viscosity applications, such as preventing leakage of drilling mud from the top drive assembly.

The RF6 sealing geometry can be modified to alter sealing performance. Please speak to one of our technical sales staff for more information This email address is being protected from spambots. You need JavaScript enabled to view it..

Available Materials
TypeTemperatureChemical CompatibilityWear ResistanceFeatures
Unfilled PTFE (1001)

 -200°C to +260°C

-328°F to +500°F

Excellent

Low

Excellent insulating capacity. High dielectric properties. Low coefficient of friction, suitable for non-stick applications. Not recommended for dynamic applications, such as loaded sleeve bearings.

Carbon Graphite Filled PTFE (1020)

-200°C to +260°C

-328°F to +500°F

Good

High

Chemical resistance in corrosive environments. Good initial wear and rubbing or sliding characteristics in both wet and dry applications. Excellent for piston rings (cylinder wear is reduced because the relatively soft CFPT surfaces entrap potentially abrasive foreign particles).

Bronze Filled PTFE (1023)

-200°C to +260°C

-328°F to +500°F

Fair

High

High thermal conductivity, with heat dissipation more rapid than in unfilled PTFE. Exhibits excellent tribiological properties in high speed dynamic applications. 

1130

-200°C to +260°C

-328°F to +500°F

Excellent

High

Designed for demanding sealing and wear applications, our proprietary 1130 blend has excellent tensile strength and elongation properties, as well as low friction.

Molyglass Filled PTFE

-200°C to +260°C

-328°F to +500°F

Good

High

Long, steady-state wear life on hardened dynamic surfaces due to a low starting coefficient of friction. Excellent for extreme high pressure and temperature conditions.

Spring Energizers

Three different spring types may be chosen in the design of an EngiSeal®. Each type displays different capacities in load curve, unit loading and deflection range. These are canted coiled springs, helical springs and V-springs.

rd engiseal canted

Canted coiled springs: 

Produces a very flat load curve when compressed. Providing constant, predictable loads throughout a very wide deflection range, canted coiled springs are used to energize U-cup seals and other components. 

rd engiseal helical

Helical springs: 

Produces a very high unit load over a narrow deflection range. Constructed from flat ribbon stainless steel and other alloys wound into a helical form with a round cross section, helical springs are used in U-Cup seals and other components. 

rd engiseal vsprings

V-Springs: 

V-Shape geometry produces a moderate load over a wide deflection range. The stainless steel (or other alloy) cantilever design of a V-spring is applied as a radial or compression energizer inside a U-cup seal and other components. 

Please contact KC Seals for information regarding load and deflection.
