Product Description
FEP encapsulated silicone o rings
 
WALLE SEALING silicone, Viton or EPDM O-Rings encapsulated with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments. WALLE SEALING combines the best qualities of two materials, FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience. This unique combination forms a highly effective, long lasting seal for the most demanding applications.

WALLE SEALING O-Rings are available in over 60 standard 
cross-section sizes from .063" (1.60mm) to 1-1/4" (31.75mm). Standard WALLE SEALING O-Rings are comprised of FEP over silicone, Viton, or EPDM, and can be used in temperatures from -75° to +400°F (-60° to +205°C) depending upon the choice of elastomer core.

For high temperature applications to 500°F (260°C), WALLE SEALING is made with PFA over silicone. PFA has higher mechanical strength than FEP or TFE at elevated temperatures and has excellent crack and stress resistance.

Encapsulated O-Rings are primarily used as a static seal (axial or radial).

 
Standard WALLE SEALING O-Rings in round or square cross-sections are manufactured in sizes to AS 568A industry standards. Non-standard sizes are also available for custom designs, along with a full range of metric (ISO) sizes.

FEP-encapsulated O-Rings (Fluorinated Ethylene Propylene):


Outstanding chemical and corrosion resistance
Low coefficient of friction
Resilience with choice of elastomeric cores
Low compression set
Temperature range: -75°F to 400°F (-60°C to 205°C)
Unlimited sizes (No tooling charges)
Solid & hollow silicone, Viton cores
FDA compliant materials available
USP Class VI approved materials available
PFA-encapsulated O-Rings (Perfluoroalkoxy). Same as FEP above but with these added benefits:
High temperature applications to 500°F (260°C)
Higher mechanical strength
Better flex-life
Low vapor permeation
Excellent stress and crack resistance
Longer wearability
Solid silicone & Viton core
Square Cross-Section Ring Seals. Same as FEP above plus:
Retrofits into standard O-Ring groove
Larger sealing surface
Less squeeze required for sealing
Effects more positive seal
Rectangular cross-sections also available
Solid silicone & Viton core
 
Did you know that walle sealing solutions also offers?
FEP or PFA encapsulated straight lengths in Silicone,
Viton, or EPDM
The straight lengths can be supplied with "open ends" or "closed ends" providing total encapsulation of the elastomer.
