Made for Your Application
Rubber gaskets are flat elastomer profiles made from sheet stock and chosen for the operating media and environment. Unlike porous foam, solid rubber provides stronger recovery and better durability where a joint faces repeated compression, movement or handling.
Material advantage
Elastomer formulation can be selected around weathering, oil contact, temperature, ozone exposure and compressive recovery.
Key features
- Resilient sealing
- broad polymer choice
- bolt-hole and window patterns
- solid or sponge rubber
- reusable profiles.

Manufacturing & Finish Options
Production process
Die cutting, waterjet cutting, CNC knife cutting and rubber-sheet slitting
Manufacturing notes
Compound, hardness, gasket land and compressed thickness are established from service media and joint loading.
Adhesive options
Optional PSA for installation retention; not usually required in bolted compression joints.
Surface options
Smooth sheet, cloth-impression, talc-free, graphite-coated or textured anti-slip surfaces.
Where It Fits
Best for
- Pipe and pump covers, weatherproof panels, machinery guards, automotive service parts, appliance doors and general equipment sealing.
Common industries
- Industrial equipment, automotive, construction, HVAC, water systems, appliances and transportation.
Consider another option when
Chemical media outside the chosen polymer’s compatibility, extreme pressure joints requiring specialised flange gaskets, or solvent-swollen elastomer service.

Design guidelines
Provide a stable gasket land and even fastening; avoid narrow bridges that can tear during installation.
Engineering notes
Specify the actual liquid, gas or weather exposure and operating temperature; polymer selection is more important than generic rubber thickness.
Selection Guide
Choose EPDM for weather and water, NBR for many oils, neoprene for balanced weather/oil performance, and silicone for higher temperature flexibility.
Material comparison
Solid rubber lasts longer under cycling than foam, while cork conforms well to rough surfaces and PTFE handles many aggressive chemicals.
Standards & requirements
Customer drawings, compound data sheets and agreed material or test requirements.
Drawing Requirements
PDF, DXF, DWG, STEP, AI, CAD screenshots and dimensioned sketches can be reviewed. Don’t have a CAD drawing? A dimensioned PDF, sketch or clear image may be sufficient for an initial review.
Frequently Asked Questions
Which rubber gasket is best for outdoor water exposure?
EPDM is a frequent choice for water, ozone and weather exposure, subject to the full service conditions.
Can rubber gaskets be supplied in custom Shore hardness?
Yes. Available hardness depends on the compound and sheet source; Shore A should be specified with the application.
Are rubber gaskets reusable?
Some can be reused if undamaged and not excessively compressed, but replacement is safer for critical seals.
What information determines the compound?
Media, temperature, outdoor exposure, compression load, required life and any regulatory requirements all influence selection.
