SWEP Viton Gaskets for Verified Gasketed Units
SWEP Viton gaskets are independently manufactured FKM replacement seals intended for verified SWEP heat exchanger configurations with openable, gasketed plate packs. FKM is considered for selected chemical, hydrocarbon, oil and elevated-temperature duties.
Many SWEP products use permanently brazed construction and do not contain replaceable plate gaskets. For an openable unit, both profile compatibility and FKM suitability must be confirmed before quotation.
Provide for FKM Review
- Complete SWEP model
- Nameplate and full-unit photos
- Plate code or gasket sample
- Complete chemical names
- Concentrations and temperatures
- Cleaning media and exposure time
A permanently brazed unit has no removable plate gaskets. Send its model and leakage details for a different equipment assessment.
Where FKM May Be Considered
FKM is not a universal chemical solution. The selected formulation must be reviewed against every process and cleaning fluid.
Chemical Processing
Selected heating, cooling and heat-recovery duties after chemical compatibility review.
High-Temperature Oils
Compatible oil circuits operating beyond the practical conditions of standard compounds.
Hydrocarbon Service
Selected hydrocarbon duties where the specific fluid and additives suit the FKM grade.
Process Heat Recovery
Recovery systems involving demanding media on one or both plate-pack circuits.
Thermal Cycling
Selected services with repeated temperature changes within confirmed compound limits.
Material Upgrades
Application reassessment after swelling, hardening or chemical attack of the old gasket.
SWEP Viton Gasket Supply Specification
| Specification | Supply or Confirmation Basis | Buyer Information Required |
|---|---|---|
| Applicable equipment | Verified openable SWEP configuration with replaceable plate gaskets | Nameplate and complete equipment photographs |
| Product type | OEM-compatible FKM replacement plate gasket | Complete model and plate details |
| Profile | Matched to plate groove, ports and sealing geometry | Plate code, images, dimensions or physical sample |
| Material | FKM compound selected for reviewed operating conditions | Chemicals, concentrations, additives and exposure time |
| Attachment | Matched to the corresponding plate-retention design | Close images of clips, tabs or bonded sections |
| Plate position | Start, channel and end configurations where applicable | Plate sequence and total plate count |
| Temperature data | Confirmed for the selected FKM formulation and media | Continuous, peak, startup and cleaning temperatures |
| Packaging | Standard export packing or agreed custom labels and packaging | Project code, unit number or private-label format |
No universal chemical or temperature rating applies to every FKM formulation. Final approval requires the complete process conditions.
Review Process and Cleaning Fluids Together
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
- Conditions exceeding standard elastomer capability
Conditions Requiring Careful Review
The specific FKM formulation must be assessed for:
- Steam or hot-water exposure
- Amines and alkaline media
- Polar solvents and ketones
- Mixed or unidentified chemicals
- High-temperature cleaning solutions
Provide chemical name, concentration, temperature, pressure, exposure duration and cleaning cycle together. The most severe condition may occur outside normal production.
Data Needed for Profile Matching
- Clear photograph of the complete SWEP nameplate
- Images showing the frame and tightening bolts
- Model and identification marked on the plate
- Front and rear photographs of an intact gasket
- Close views of ports and gasket-retention points
- Plate dimensions if identification is incomplete
- Plate count and required gasket quantity
Confirm Why FKM Is Required
Changing from NBR or EPDM to FKM should address a verified process requirement. A higher-cost compound does not automatically provide longer service life in every medium.
- Identify the failure mode of the old gasket.
- Check whether process chemistry changed.
- Include cleaning chemicals in the review.
- Confirm actual peak exposure temperature.
From Unit Verification to FKM Gasket Packing
Check Construction
Equipment images confirm that the plate pack uses removable gaskets.
Match the Profile
Plate groove, ports, sealing ribs and retaining points are reviewed.
Review FKM
Chemicals, concentrations, temperatures and cleaning cycles are assessed.
Inspect and Pack
Finished gaskets are checked and packed by confirmed order details.
For Maintenance Teams
Separate each exchanger by model, unit number, plate count and service medium. Record why FKM is required when replacing a different elastomer.
For Distributors and OEM Buyers
Provide the verified gasketed model range, FKM requirements, quantity per item, labeling format and destination. Custom packaging can be reviewed with the order.

SWEP Viton Gasket FAQ
Do all SWEP heat exchangers use Viton gaskets?
No. Many SWEP units are brazed heat exchangers without replaceable elastomer gaskets. Construction must be verified before requesting FKM replacements.
What applications are SWEP FKM gaskets considered for?
FKM is evaluated for selected chemicals, oils, hydrocarbons and elevated-temperature duties after the exact process and cleaning conditions are reviewed.
Is FKM compatible with every chemical?
No. FKM formulations have specific limitations. Chemical name, concentration, temperature and exposure duration must be checked before selection.
What temperature can a SWEP FKM gasket withstand?
The allowable temperature depends on the FKM formulation, process fluid and exposure cycle. Submit continuous, peak and cleaning temperatures for confirmation.
Can FKM gaskets be installed in a brazed SWEP unit?
No. A standard brazed plate pack is permanently joined and does not contain replaceable plate gaskets.
Is FKM always better than NBR or EPDM?
No. Each elastomer has different strengths and limitations. The correct choice is the compound compatible with the actual media, temperature and cleaning process.
Are these original SWEP 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.
