SummaryNingbo Rilson Sealing Material Co., Ltd. is identified as both a trading company and manufacturer/factory in Ningbo, Zhejiang, China, specializing in fluid sealing systems, spiral wound gaskets, ring joint gaskets, and related sealing materials.

Reported production includes 3,000,000 spiral wound gaskets, 800,000 kammprofile gaskets, and 1,000,000 ring joint gaskets. It exports to multiple global regions, with exports representing 71%–90% of total sales, and reports lead times of within 15 working days off-season and one month during peak season. Evidence is insufficient to assess after-sales service, financial credibility, and customer cases.
Supplier typeThe supplier is explicitly described as both a trading company and manufacturer/factory, while its industry is identified as manufacturing and its listed products and factory location support manufacturing involvement. However, one record also classifies the company nature as a trading company, indicating a mixed or inconsistent classification.
CertificationsThe supplier explicitly states that it holds ISO 9001:2015 and API certificates, and ISO 9001 is separately listed under supplier management-system certification. This provides direct evidence of formal quality-management certification and an API-related certification claim.
R&D capabilityThe supplier describes itself as an enterprise integrating science and technology, offers technical solutions, and reports 6–10 R&D engineers with fluid-sealing technology expertise. These statements support the existence of R&D capability, although no specific patents, new-product records, or measurable innovation outcomes are provided.
Production capacityReported output includes 3,000,000 spiral wound gaskets, 800,000 kammprofile gaskets, and 1,000,000 ring joint gaskets; the supplier also operates more than 10 production lines and reports lead times of within 15 working days off-season and one month during peak season. These details directly support substantial production capacity, though the full annual capacity for some products is not specified.
Customization capabilityThe supplier explicitly states that it provides OEM and ODM services and offers various technical solutions, while its product scope includes sealing gaskets and materials. This directly supports capability to handle customized products or solutions.
