Alfa Laval EPDM Gaskets for Compatible Water-Based Duties
Alfa Laval EPDM gaskets are independently manufactured replacement seals matched to confirmed Alfa Laval gasketed plate heat exchanger models. EPDM is commonly considered for compatible hot-water, HVAC, water-glycol and other aqueous applications.
Correct selection requires both profile matching and material review. The gasket must fit the plate groove, ports and attachment points, while the EPDM compound must suit the process fluids, temperatures, additives and cleaning cycle.
Provide for EPDM Review
- Alfa Laval exchanger model
- Plate code and gasket photos
- Media on both circuits
- Fluid concentration and additives
- Continuous and peak temperatures
- Cleaning media and temperature
Where EPDM May Be Considered
Final material selection should use the complete fluid composition and operating cycle rather than the general name of the application.
Hot-Water Circulation
Compatible heating and hot-water duties within confirmed EPDM conditions.
HVAC Water Systems
Selected chilled-water and heating-water circuits in commercial or industrial systems.
Industrial Water Cooling
Selected cooling- and process-water duties after water chemistry is reviewed.
Water-Glycol Circuits
Compatible mixtures when glycol type, concentration and additives are disclosed.
Aqueous Heat Recovery
Compatible water-based circuits used for process heating, cooling or energy recovery.
Plate-Pack Overhauls
Complete EPDM gasket-set replacement during plate inspection and cleaning.

| Gasket profile | Matched to plate groove, sealing ribs and port geometry | Plate code, photographs, drawing or sample |
| Material | EPDM compound subject to application compatibility review | Media, concentration, additives and temperatures |
| Attachment method | Matched to the corresponding plate and retention design | Images showing clips, tabs or bonded sections |
| Plate position | Start, channel and end-plate arrangements where applicable | Plate sequence and total plate count |
| Operating conditions | Confirmed for the proposed EPDM formulation and media | Continuous, peak, startup and cleaning conditions |
| Inspection | Appearance, profile consistency and order identification checks | Any agreed project-specific requirements |
| Packaging | Standard export packing or agreed custom labels and packaging | Unit number, project code or private-label format |
A universal EPDM temperature value is not stated because suitability changes with formulation, process media, cleaning chemicals and exposure cycle.
Review Every Fluid That Contacts the Gasket
Common EPDM Selection Contexts
EPDM is commonly evaluated for compatible duties involving:
- Hot- and cold-water circulation
- Selected HVAC water systems
- Compatible water-glycol mixtures
- Selected aqueous process solutions
- Compatible cleaning and rinse cycles
Conditions Requiring Caution
EPDM may be unsuitable where the gasket encounters:
- Mineral oils and lubricating oils
- Petroleum-derived process fluids
- Hydrocarbon contamination
- Unidentified chemical additives
- Unverified cleaning solutions
Chemical name, concentration, temperature and exposure duration should be reviewed together. Check the cleaning stage as well as normal production.
Data Needed to Match the Alfa Laval Plate
- Complete exchanger nameplate photograph
- Alfa Laval model and plate identification code
- Front and rear photographs of an intact gasket
- Close images of port rings and attachment points
- Plate dimensions if identification is incomplete
- Plate count and required gasket quantity
- Existing attachment method and gasket arrangement
Do Not Select EPDM by Color
Gasket color does not reliably identify an elastomer or its formulation. Used rubber may also change appearance after exposure to heat, process fluids and cleaning chemicals.
- Check maintenance and material records.
- Confirm whether the process fluid changed.
- Include every cleaning chemical.
- Use the plate groove as the profile reference.
Control Compression and Temperature Changes
Factors Affecting EPDM Service
- Correct plate and gasket profile
- Compatibility with both process circuits
- Compatibility with cleaning solutions
- Uniform plate-pack compression
- Controlled pressure and temperature changes
Signs Requiring Inspection
- Hardening or permanent flattening
- Swelling, softening or surface damage
- Cracks around ports or retaining points
- Repeated gasket displacement
- External leakage at the plate-pack edge
From Model Identification to EPDM Gasket Packing
Identify the Plate
Model, plate code, photographs, dimensions and sample are reviewed.
Review EPDM
Media, additives, temperatures and cleaning cycles are assessed.
Confirm the Order
Profile, arrangement, compound, quantity and labels are agreed.
Inspect and Pack
Finished gaskets are checked and separated by order details.
For Maintenance and Engineering Teams
Separate each exchanger by model, unit number and plate count. Preserve the plate sequence and inspect gasket grooves before fitting the replacement EPDM set.
For Distributors and OEM Buyers
Provide the required model range, EPDM specification, quantity per item, labeling format and destination. Custom packaging can be reviewed with the order.

Alfa Laval EPDM Gasket FAQ
What applications are Alfa Laval EPDM gaskets considered for?
EPDM is commonly evaluated for compatible hot-water, HVAC, water-glycol and other aqueous duties after fluid and temperature conditions are reviewed.
Are these genuine Alfa Laval EPDM gaskets?
No. They are independently manufactured, OEM-compatible EPDM replacement gaskets matched to confirmed Alfa Laval plate heat exchanger models.
Is EPDM suitable for oil service?
EPDM is generally not selected for mineral oils, petroleum fluids or hydrocarbon exposure. Provide the complete medium composition for material review.
What temperature can an Alfa Laval EPDM gasket withstand?
The allowable temperature depends on the EPDM formulation, process fluid, cleaning chemicals and exposure cycle. Submit continuous, peak and cleaning temperatures.
Can an EPDM gasket be identified by its color?
No. Color is not a dependable material specification. Use maintenance records or select the compound from verified process conditions.
Can an older Alfa Laval EPDM gasket be matched from a sample?
Sample-based assessment may be possible. An intact gasket, its corresponding plate, equipment nameplate and plate dimensions provide the strongest reference.
Can complete Alfa Laval EPDM gasket sets be supplied?
Yes, subject to profile availability and application review. Provide the model, plate count and arrangement so all required gasket configurations can be confirmed.
