Alfa Laval Gaskets for Planned PHE Maintenance
Alfa Laval replacement gaskets are independently manufactured seals matched to confirmed Alfa Laval plate heat exchanger models. They are used when existing gaskets have aged, hardened, cracked, swollen, detached or lost the elasticity required to maintain uniform sealing contact.
Replacement selection must address the plate profile, port arrangement, attachment method and rubber compound. WTSML confirms these details before preparing individual quantities or complete plate-pack gasket sets.
Prepare Before Quotation
- Complete exchanger model
- Plate code and gasket photos
- Media on both circuits
- Operating and cleaning temperatures
- Number and arrangement of plates
- Shutdown date and destination
When Should the Gaskets Be Replaced?
Inspect the complete sealing system. External leakage may involve the gasket, plate groove, plate sequence or plate-pack compression.
Loss of Elasticity
Hardened or permanently flattened rubber may no longer recover after compression.
Cracks or Tears
Cuts, surface cracks and damaged locating points can interrupt the sealing path.
Chemical Swelling
Softening, swelling or distortion can indicate an unsuitable gasket compound.
Repeated Displacement
A gasket leaving its groove may indicate profile, installation or compression problems.
External Leakage
Leakage at the plate-pack edge requires inspection of seals, grooves and tightening.
Planned Overhaul
A shutdown provides access to assess the complete gasket set and plate condition.
Alfa Laval Replacement Gasket Specification
| Order Item | Supply or Confirmation Basis | Buyer Information Required |
|---|---|---|
| Product type | OEM-compatible replacement gasket for Alfa Laval gasketed PHE models | Complete exchanger model |
| Gasket profile | Matched to plate groove, sealing ribs and port geometry | Plate code, photographs, drawing or physical sample |
| Material options | NBR, EPDM or FKM, subject to application review | Media, concentrations, 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 configurations where applicable | Plate sequence and number of plates |
| Order format | Individual replacement quantity or complete plate-pack set | Maintenance scope and spare-parts requirement |
| 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 |
Exact dimensions and operating limits depend on the confirmed plate profile, gasket compound and process conditions.
Confirm Whether the Existing Compound Is Still Correct
A replacement project is an opportunity to verify the gasket material against current operating conditions. Do not assume the removed gasket was correctly selected.
NBR
Commonly evaluated for compatible lubricating oils, hydraulic fluids and selected utility duties.
Provide oil type, base stock, additives and temperatures.
Oil-related serviceEPDM
Commonly evaluated for compatible hot-water, HVAC and aqueous duties.
Mineral-oil and hydrocarbon exposure must be disclosed.
Water-based serviceFKM
Considered for selected chemicals, hydrocarbons, oils and elevated-temperature duties.
Complete chemical and cleaning-process data are required.
Demanding process serviceWhat to Send for Profile Matching
- Complete Alfa Laval exchanger nameplate photograph
- Model and identification marked on the plate
- Front and rear photographs of an intact gasket
- Close images of port rings and attachment points
- Plate dimensions when identification is incomplete
- Total plate count and required gasket quantity
- Existing gasket arrangement and attachment method
Do Not Measure Only the Used Gasket
Aged rubber can stretch, shrink, flatten or swell. Its dimensions may no longer represent the original molded profile.
- Use the matching plate groove as the primary reference.
- Keep the gasket flat while taking photographs.
- Provide an undamaged sample where possible.
- Do not identify the compound by color alone.
Plan the Replacement Set Before Opening the PHE
Procurement Checklist
- Confirm the model and plate code.
- Verify the plate count and flow arrangement.
- Review the gasket compound against current media.
- Separate spares by exchanger and unit number.
- Allow for any damaged plates found during inspection.
Maintenance Checklist
- Record the plate sequence before disassembly.
- Inspect plates for cracks, corrosion and deformation.
- Clean gasket grooves without scratching them.
- Remove residual adhesive where required.
- Check the frame and tightening components.
Restore Uniform Gasket Compression
During Gasket Installation
- Compare the new profile with the approved reference.
- Place each gasket into the groove without stretching.
- Check port rings and retaining points individually.
- Keep plates and gasket surfaces free from debris.
During Plate-Pack Reassembly
- Restore the correct plate sequence and orientation.
- Use the required tightening sequence and dimension.
- Inspect plate edges for displaced gasket sections.
- Avoid uncontrolled pressure and temperature changes at startup.
From Maintenance Data to Packed Gasket Sets
Identify
Review the model, plate code, photographs and available sample.
Review Service
Check the media, temperatures, additives and cleaning conditions.
Match Profile
Confirm the sealing path, ports, retainers and plate position.
Confirm Set
Agree the quantity, arrangement, labeling and packaging.
Inspect and Pack
Check finished gaskets and separate sets by order identification.
For Maintenance and Engineering Teams
List each exchanger separately by model, unit number, plate count, gasket material and shutdown date. This reduces mixing risk when several similar units are serviced together.
For Distributors and OEM Buyers
Provide the required model range, material, quantity per item, labeling format and destination. Custom packaging can be reviewed with the order.

Alfa Laval Replacement Gasket FAQ
Are these original Alfa Laval replacement gaskets?
No. They are independently manufactured, OEM-compatible replacement gaskets matched to confirmed Alfa Laval plate heat exchanger models.
When should Alfa Laval PHE gaskets be replaced?
Replacement should be considered when gaskets are hardened, cracked, swollen, damaged, displaced or unable to recover compression. Plate and groove condition should also be inspected.
Can a complete gasket set be supplied for one heat exchanger?
Yes, subject to profile availability and application review. Provide the model, plate count and arrangement so every required gasket configuration can be confirmed.
Can the gasket profile be identified from an old sample?
Sample-based assessment may be possible, but the matching plate is a more reliable geometric reference because an old gasket may be stretched, flattened or swollen.
Should the original gasket material always be used?
Not automatically. Confirm whether the process fluid, additives, temperature or cleaning procedure has changed before selecting NBR, EPDM or FKM.
Can gaskets be reused after plate cleaning?
Reuse depends on gasket age, elasticity, retention condition and service history. Hardened, damaged, swollen or permanently deformed gaskets should not be reused.
What information is needed for a replacement gasket quotation?
Include the exchanger model, plate code, gasket photographs, media, operating and cleaning temperatures, plate count, quantity, packaging needs and destination.
Prepare the Correct Gasket Set Before the Shutdown
Send the Alfa Laval model, plate code, gasket photos, process conditions, plate count, required quantity and destination.
