Marine Gaskets, Washers, and Seals

Cannon Gasket is ISO 9001 certified with PSA backing for field installation and custom weather-strip profile capability. Fabricating sealing components since 1971. Send profiles, service environment, and volume for material selection, tooling cost if needed, quoted pricing, and lead time.

Quick facts about Marine
  1. Serving boat builders, marine engine manufacturers, and marine electronics OEMs where salt water, UV, and vibration shorten elastomer life.
  2. Used for hatch and deck seals, weather strips, engine gaskets, vibration dampening mounts, enclosure gaskets, and fuel-system components.
  3. Fabricated from UV- and ozone-rated EPDM, Neoprene, silicone, polyurethane, cork-rubber, and closed-cell foam stock.

Sealing components for marine

Marine equipment runs in one of the most aggressive operating environments, with saltwater, UV, ozone, vibration, and constant moisture all working against elastomer life. Cannon Gasket supplies custom marine seals and gaskets in compounds chosen for sustained saltwater and outdoor exposure, die-cut and lathe-cut to customer drawings and supplied to boat builders, marine engine manufacturers, and marine electronics OEMs.

Where marine sealing shows up

  • Hatch and deck seals (EPDM)
  • Weather strips for windows and doors
  • Marine engine gaskets (Nitrile, silicone)
  • Vibration dampening mounts (Neoprene, polyurethane)
  • Marine electronics enclosure gaskets
  • Fuel system components

Marine Sealing Applications and Suited Materials

Deck hardware relies on EPDM and neoprene gaskets and washers under cleats, hatches, and through-deck fittings, while window and hatch weatherstrip uses EPDM sponge and silicone sponge to survive UV-exposed service. Propulsion and drive components call for different compounds depending on the fluid: Viton and fluorosilicone handle fuel-system seals, and Nitrile suits hydraulic service. Bilge and pump sealing uses neoprene and EPDM for water and oil-mix service, and electrical enclosures are sealed with silicone and neoprene for marine-grade IP-rated housings. Matching the compound to the fluid, temperature, and exposure on each part keeps seals serviceable in continuous saltwater and sunlight.

Materials We Supply for Marine

Cannon supplies EPDM and neoprene, the long-standing marine standard, alongside Viton, fluorosilicone, silicone, Nitrile, polyurethane, and UHMW. For fastener isolation we supply polymer composites. These compounds are selected for the loads each part sees, from UV- and ozone-rated elastomers for exposed weatherstrip to fuel-resistant fluoroelastomers for propulsion seals, so material choice follows the service environment rather than a single default stock.

Production and Quality Considerations

Cannon is ISO 9001 certified and recommends UV-stabilized formulations for parts under sustained sunlight and saltwater-corrosion-aware material recommendations. PSA backing is available for field installation, and custom weather-strip profiles are available. Parts can be custom kitted into service kits for marine repair programs, which keeps the correct seals together for field replacement. Send profiles, service environment, and volume for material selection, tooling cost if needed, quoted pricing, and lead time.

Frequently Asked Questions

Questions from marine buyers.

Are you ISO 9001 certified?
Yes, ISO 9001:2015 certified. Documented quality management covers incoming material verification, in-process inspection, calibrated measurement, final inspection, non-conformance handling, corrective action, and full lot traceability. AS9100-ready for aerospace, with MIL-spec and FDA 21 CFR 177.2600 / USP Class VI grades available on request.
Do you serve general industrial OEMs?
Yes. Automotive, Electronics, Industrial Controls, HVAC, Plumbing, Irrigation, Pool & Spa, and Marine programs all run custom gaskets and washers through our Fontana facility. JIT, VMI, and Kanban replenishment available on ongoing programs.
Which materials resist saltwater and marine exposure?
EPDM and Neoprene for topside weather and UV, Viton and HNBR for fuel-system components, silicone for electronics enclosures, and closed-cell neoprene foam for above-deck environmental sealing.
Which regulated industries do you serve?
Aerospace (AS9100-ready), Medical & FDA (ISO 7 clean room, USP Class VI), Food & Beverage (FDA 21 CFR 177.2600), Oil & Gas (chemical-resistant elastomers), and Defense (US-based production, MIL-spec compounds).
How fast do you return a quote?
Most RFQs come back within one business day. Simple profile updates to an existing tool quote same-day. Send a drawing, DXF, or competing part number and our engineering team reviews material, tolerance, and volume before pricing.
What is the minimum order quantity?
Minimums depend on the part and material. We cut prototype and first-article quantities for engineering evaluation, then scale up to production volumes from the same tooling. For high-volume programs we run JIT, VMI, and Kanban replenishment out of Fontana, California.
What should I send with an RFQ?
Ideal: a drawing or DXF, material spec (or compound family), estimated annual volume, and any regulatory callouts (FDA, USP Class VI, AS9100, MIL-spec). If you only have a sample or a part number from a competing supplier, send that and we will reverse-engineer the spec before quoting.
What are typical lead times?
Prototype and first-article parts usually ship in 5-10 business days. Production runs from existing tooling are 2-3 weeks depending on volume and material lead time. Rush and expedite options available on a case-by-case basis.
