Alfa Laval NBR Gaskets for Compatible Oil and Utility Duties
Alfa Laval NBR gaskets are independently manufactured replacement seals matched to confirmed Alfa Laval gasketed plate heat exchanger models. NBR is commonly considered for compatible lubricating oils, hydraulic fluids and selected industrial utility duties.
Correct supply requires both geometric and material matching. The gasket must fit the plate groove, port geometry and retaining points, while the NBR compound must suit the oil type, additives, operating temperature and cleaning process.
Provide for NBR Review
- Alfa Laval exchanger model
- Plate code and gasket photos
- Complete oil or fluid name
- Base stock and additives
- Continuous and peak temperatures
- Cleaning media and temperature
Where NBR May Be Considered
Oil formulations differ. Final selection requires the complete fluid specification rather than a broad description such as "lubricating oil" or "hydraulic oil."
Lubricating-Oil Cooling
Selected lubrication circuits after oil grade, additives and temperatures are reviewed.
Hydraulic-Oil Service
Compatible hydraulic-fluid cooling duties with a complete fluid specification.
Industrial Oil Cooling
Selected machinery and process-oil circuits within confirmed compound conditions.
Utility Water Duties
Selected water-based services where chemistry and temperature are compatible with NBR.
Oil-to-Water Cooling
Thermal systems handling compatible oil on one side and utility water on the other.
Plate-Pack Overhauls
Complete NBR gasket-set replacement during plate inspection and cleaning.
Alfa Laval NBR Gasket Supply Specification
| Specification | Supply or Confirmation Basis | Buyer Information Required |
|---|---|---|
| Product type | OEM-compatible NBR gasket for Alfa Laval gasketed plate heat exchangers | Complete exchanger model |
| Gasket profile | Matched to plate groove, sealing ribs and port geometry | Plate code, photographs, drawing or physical sample |
| Material | NBR compound subject to fluid and temperature review | Fluid name, grade, base stock, additives and concentration |
| 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 NBR formulation and process 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 NBR temperature value is not stated because suitability changes with compound formulation, fluid composition, additives and exposure duration.
Specify the Oil and Its Additive Package
Typical NBR Review Contexts
NBR is commonly evaluated for compatible duties involving:
- Selected mineral-based lubricating oils
- Compatible hydraulic fluids
- Selected machinery and process oils
- Compatible industrial utility water
- Oil-to-water cooling circuits
Conditions Requiring Separate Review
Do not assume standard NBR is suitable for:
- Unidentified synthetic oils
- Aromatic or aggressive solvents
- Strong oxidizing chemicals
- High-temperature cleaning solutions
- Fluid mixtures with unknown additives
Compatibility depends on composition, concentration, temperature and exposure duration. Review process and cleaning fluids together.
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 Measure Only the Used Gasket
An old NBR gasket may be stretched, flattened, hardened or swollen. Its dimensions may no longer represent the correct molded profile.
- Use the plate groove as the primary reference.
- Keep the gasket flat for photographs.
- Provide an intact section where possible.
- Do not identify NBR from color alone.
Control Compression, Pressure and Temperature Changes
Factors Affecting NBR Service
- Correct gasket profile and plate sequence
- Compatibility with oil and all additives
- Compatibility with cleaning solutions
- Uniform plate-pack compression
- Controlled pressure and temperature changes
Signs Requiring Inspection
- Hardening or permanent flattening
- Swelling, softening or surface deterioration
- Cracks around ports or retention points
- Repeated gasket displacement
- External leakage at the plate-pack edge
Protect the Gasket Groove and Sealing Surface
Before Installation
- Clean the plate groove without scratching it.
- Remove residual adhesive where required.
- Compare the new profile with the approved reference.
- Reject plates with damaged sealing surfaces.
During Reassembly
- Restore the correct plate order and orientation.
- Ensure each port ring sits flat in the groove.
- Follow the required tightening sequence and dimension.
- Avoid uncontrolled pressure shocks at startup.
From Model Identification to NBR Gasket Packing
Identify the Plate
Model, plate code, photographs, dimensions and sample are reviewed.
Review NBR
Oil type, additives, temperatures and cleaning conditions 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 NBR set.
For Distributors and OEM Buyers
Provide the required model range, NBR specification, quantity per item, labeling format and destination. Custom packaging can be reviewed with the order.

Alfa Laval NBR Gasket FAQ
What applications are Alfa Laval NBR gaskets considered for?
NBR is commonly evaluated for compatible lubricating oils, hydraulic fluids and selected industrial utility duties after the complete fluid specification is reviewed.
Are these genuine Alfa Laval NBR gaskets?
No. They are independently manufactured, OEM-compatible NBR replacement gaskets matched to confirmed Alfa Laval plate heat exchanger models.
Is NBR suitable for every oil?
No. Base oils, synthetic formulations and additive packages vary. Provide the complete fluid name or technical data for compound review.
What temperature can an Alfa Laval NBR gasket withstand?
The allowable temperature depends on the NBR formulation, fluid, additives and exposure cycle. Submit continuous, peak and cleaning temperatures.
Can an NBR 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 NBR 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 NBR 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.
