Key features

Multi-Chamber Hollow Design: The hollow structure provides excellent flexibility and compression recovery, adapting to uneven gaps while maintaining uniform sealing pressure.

Dual-Material Composite Construction: The solid rubber base offers structural support and mounting stability, while the sponge rubber lips deliver soft, noise-reducing sealing performance.

Superior Weather & Aging Resistance: EPDM material provides outstanding ozone, UV, and weather resistance, maintaining flexibility and performance in outdoor environments for years.

High Compression Set Resistance: Resists permanent deformation under repeated opening/closing, ensuring consistent sealing over the product's lifespan.

Enhanced Noise & Vibration Damping: The multi-chamber structure effectively absorbs sound and vibration, reducing noise transmission in automotive and industrial applications.

Custom Fit Profiles: We can extrude nearly any multi-chamber composite profile based on your drawings or samples, ensuring a perfect fit for your specific application.

AI-Powered supplier vetting

SummaryThe supplier identifies itself as a factory and reports broad customization, ODM, OEM for well-known brands, raw-material traceability, and 100% finished-product inspection. It has export experience, self-operated import/export rights, overseas installation and maintenance services, and stated production of approximately 20 production lines annually. Evidence also indicates more than 200 domestic and overseas rubber-enterprise customers. However, the supplier lacks written procedures or records for service assessment, corrective and preventive actions, and complaint handling; it also reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and no available SDK. Certification evidence is limited to a company description referencing an ISO 2000 management system, without documentation or a clearly identified certification standard.

Supplier typeThe supplier explicitly identifies its company nature as a factory. Its description also presents production capacity and equipment-related manufacturing activities, supporting classification as a manufacturing supplier rather than only a trading or service entity.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and broad R&D design services. It does not have an available SDK, but the evidence still explicitly supports active product development and design capability.

Production capacityThe supplier reports lathe and drilling-machine facilities, in-stock capability, and annual production of about 20 production lines while serving more than 200 rubber enterprises. A deficiency is indicated by the absence of a valid manufacturing-capacity contract with related subcontractors, but the stated factory capacity and equipment support production capability overall.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, minor customization, flexible customization, and full customization. This is explicit evidence of a broad customization offering.

Client casesThe supplier reports OEM service for well-known brands, serving more than 200 well-known rubber enterprises domestically and overseas, and exporting for 16 years with 51%–70% of sales from exports. These statements provide substantial customer and market-experience evidence, although individual customer names or documented case studies are not supplied.

Product Q&A

Q:What materials are used for these multi-chamber composite seals?

We mainly use EPDM solid + sponge rubber composite for standard products. We can also provide NBR (oil-resistant), silicone (high/low temperature resistant), and other custom compounds based on your requirements.

Q:Can you produce custom cross-section profiles?

Yes, we offer full OEM & ODM customization. We can extrude any multi-chamber composite profile according to your drawings or physical samples, with custom size, hardness, and length options.

Q:What is the temperature resistance range?

Standard EPDM composite: -40 degree Celsius to +120 degree Celsius Silicone composite: -50 degree Celsius to +180 degree Celsius Special grades are available upon request.

Q:What are the advantages of the multi-chamber hollow design?

The multi-chamber structure offers: Superior compression recovery and uniform sealing pressure Enhanced noise and vibration damping performance Reduced permanent deformation, ensuring long-term sealing stability

Q:Are these composite seals durable and long-lasting?

Yes. The EPDM material offers outstanding ozone, UV, and weather resistance, maintaining performance for years in outdoor and automotive applications. The composite design resists permanent deformation under repeated use.
