Can damaged seals still be matched?

In many cases, yes. If the old seal is deformed, groove dimensions and equipment information are especially helpful.

Can you produce according to a sample?

Yes. Sample-based production can be evaluated together with dimensional and application data.

Who normally buys DAS replacement seals?

Typical buyers include hydraulic repair shops, seal distributors, cylinder rebuilders and heavy equipment service companies.

Can you supply multiple sizes in one order?

Yes. Different sizes can be reviewed together according to the required quantity and specification list.

How can I confirm the correct DAS size?

Please provide ID, OD, height or groove dimensions for confirmation.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trade company associated with manufacturing companies producing composite-material components and metal floating seals. It holds an ISO9001:2015 certificate, maintains documented corrective-action and complaint-handling procedures, and reports in-stock capability, defined inspection instructions, seven quality inspectors, ERP-based operational management, and flexible customization. However, the records show no quality assurance in quality-control processes, no valid manufacturing-capacity contract with an affiliated subcontractor, no overseas warehouse, showroom, agent, or branch, and zero countries listed for overseas services. Innovation evidence is limited: no new products were developed in the past year and no SDK is available, although ODM and OEM services are offered. The supplier has participated in Shanghai PTC 2023 and states OEM service for well-known brands, but no specific customer names or verifiable case details are provided.

CertificationsThe supplier holds an ISO9001:2015 certificate, providing explicit evidence of a certified supplier management system.

After-Sales capabilityDocumented and followed procedures exist for corrective and preventive actions and customer complaints. The supplier also reports in-stock capability and defined service procedures, but lacks overseas warehouses, showrooms, agents, and branches, with zero countries listed for overseas services.

Production capacityAssociated manufacturing operations cover composite products, floating seals, machining, pressing, drying, vulcanization, CNC, and injection facilities. The supplier reports inventory capability, seven quality inspectors, random finished-product inspection, ERP integration, and export sales of 41%–50%, but no valid manufacturing-capacity contract is recorded and quality assurance in quality-control processes is explicitly marked absent.

Customization capabilityThe supplier explicitly provides flexible customization and ODM services, and also reports OEM service for well-known brands. These statements support a positive assessment of customization capability.
