Polaris Viton Gaskets for Demanding Chemical and Thermal Duties
Polaris Viton gaskets are OEM-compatible FKM replacement seals produced for confirmed Polaris plate heat exchanger models. FKM is considered where selected chemicals, oils or elevated process temperatures require greater resistance than standard NBR or EPDM compounds can provide.
Viton selection must use the exact chemical composition, concentration and complete operating cycle. The material name alone does not confirm suitability because different FKM formulations can respond differently to the same process environment.

Where FKM Gaskets May Be Considered
FKM is generally evaluated for demanding applications only after every fluid and operating condition has been identified.
Chemical Processing
Selected chemical heating, cooling and heat-recovery duties after full compatibility review.
High-Temperature Oils
Compatible oil circuits operating beyond the practical conditions of the existing compound.
Hydrocarbon Service
Selected hydrocarbon applications where the specific fluid and additives suit the FKM grade.
Process Heat Recovery
Recovery systems involving demanding media on one or both sides of the plate pack.
Thermal Cycling
Selected services with repeated temperature changes within the confirmed compound limits.
Maintenance Upgrades
Material reassessment when the existing gasket shows swelling, hardening or chemical attack.
Polaris Viton Gasket Supply Specification
| Specification | Supply or Confirmation Basis | Buyer Information Required |
|---|---|---|
| Product type | OEM-compatible FKM replacement gasket for Polaris plate heat exchangers | Complete exchanger model |
| Profile | Matched to the approved plate groove, sealing ribs and port geometry | Plate code, photographs, drawing or physical sample |
| Material | FKM compound selected according to reviewed operating conditions | Chemical names, concentration, additives and exposure time |
| Attachment | Matched to the plate and original gasket-retention design | Images of clips, tabs or bonded sections |
| Plate position | Start, channel and end-plate arrangements where applicable | Plate-pack sequence and number of plates |
| Temperature conditions | Confirmed for the selected FKM formulation and process medium | Continuous, peak, startup and cleaning temperatures |
| Inspection | Appearance, profile consistency and order identification checks | Any project-specific inspection requirement |
| Packaging | Standard export packing or agreed custom labels and packaging | Project code, unit number or private-label format |
No universal temperature or chemical-resistance claim applies to every FKM formulation. Final approval requires the complete process conditions.
FKM Is Not a Universal Chemical Solution
Typical FKM Review Contexts
FKM is commonly evaluated for compatible duties involving:
- Selected oils and hydrocarbon fluids
- Selected acids and process chemicals
- Elevated-temperature process media
- Chemical heat-recovery applications
- Services that exceed standard-compound capability
Conditions Requiring Careful Review
The suitability of the specific FKM grade must be checked for:
- Steam or hot-water exposure
- Amines and alkaline media
- Polar solvents and ketones
- Mixed or unidentified chemicals
- High-temperature cleaning solutions
Chemical name, concentration, temperature, pressure, exposure duration and cleaning cycle should be supplied together. Reviewing only the primary process fluid can overlook the most severe condition.
Confirm the Polaris Gasket Geometry
- Photograph the complete exchanger nameplate.
- Record the Polaris model and plate code.
- Provide front and rear views of an intact gasket.
- Include close views of port rings and retaining points.
- Measure the plate when identification marks are unavailable.
- State the plate count and required gasket quantity.
Check the Reason for Material Change
Replacing NBR or EPDM with FKM should address a verified operating requirement. A higher-cost material does not automatically provide longer service life in every medium.
- Identify the failure mode of the removed gasket.
- Check whether the process chemistry changed.
- Include cleaning fluids in the material review.
- Confirm the highest actual exposure temperature.
Profile and FKM Compound Confirmation
WTSML operates rubber molding and final-inspection workshops under an ISO 9001-certified quality management system.
Identify the Plate
Model, plate code, photographs, dimensions and samples are reviewed.
Review the Media
Chemicals, concentrations, temperatures and cleaning cycles are checked.
Confirm Supply
Profile, FKM compound, quantity, arrangement and labels are agreed.
Inspect and Pack
Finished gaskets are checked and separated by the confirmed order details.
For Maintenance and Engineering Teams
List each exchanger by model, unit number, plate count and service medium. Include the reason for changing to FKM when the original gasket used another elastomer.
For Distributors and OEM Buyers
Custom labeling and packaging can be discussed after the Polaris model range, FKM requirements, quantity, destination and private-label format are confirmed.

Polaris Viton Gasket FAQ
What are Polaris Viton gaskets used for?
FKM gaskets are considered for selected chemicals, oils, hydrocarbons and elevated-temperature duties after the specific formulation and operating conditions are reviewed.
Are these genuine Polaris or Chemours Viton gaskets?
No. They are independently manufactured, OEM-compatible FKM replacement gaskets. Any specific branded compound requirement must be stated and confirmed separately.
Is FKM suitable for every chemical?
No. FKM is not universally resistant to all chemicals. Exact media, concentration, temperature and exposure duration must be checked before selection.
What temperature can a Polaris FKM gasket withstand?
The allowable temperature depends on the FKM formulation, process fluid and exposure cycle. Provide continuous, peak and cleaning temperatures for confirmation.
Is FKM always a better choice than NBR or EPDM?
No. Each elastomer has different strengths and limitations. The best material is the one compatible with the actual media, temperature and cleaning conditions.
Can an older Polaris FKM gasket be matched from a sample?
Yes. An intact gasket and its corresponding plate can support profile matching. Material selection still requires verified process and cleaning conditions.
Can complete Polaris FKM gasket sets be supplied?
Yes. Provide the exchanger model, plate count and plate arrangement so the required start, channel and end-plate configurations can be confirmed.
Confirm FKM Compatibility Before Ordering
Send the Polaris model, gasket photographs, complete chemical composition, temperatures, cleaning conditions, quantity and destination.
