Zhejiang Jiacheng expands its push in industrial sealing

Zhejiang Jiacheng New Material Co., Ltd. is highlighting its O-rings, X Ring Quad Rings and ED Seal Rings as demand grows for more specialized sealing parts in industrial equipment. The China-based manufacturer says its global sales network and expanded R&D and quality capabilities are helping it compete in a market where customization and material selection matter more than ever.

Why it matters: - Industrial equipment makers need sealing parts that can handle pressure, movement, heat and chemical exposure without leaking. - Zhejiang Jiacheng New Material Co., Ltd. is positioning itself around that need with a broader portfolio of standard and custom sealing products. - The shift from generic parts to application-specific seals gives specialized manufacturers more room to compete on engineering, not just price.

What happened: - Zhejiang Jiacheng New Material Co., Ltd., founded in 1994 in Haining, Zhejiang, is promoting its role as a supplier of rubber seals for industrial use. - The company offers O-rings, X Ring Quad Rings, ED Seal Rings, rubber gaskets, rubber strips, FEP-encapsulated O-rings, V-ring seals and customized rubber sealing products. - The manufacturer says its sales network reaches Europe, America, the Middle East, Southeast Asia and other regions. - The company is working to build its SJK brand into an internationally recognized sealing brand.

The details: - X Ring Quad Rings use an X-shaped cross-section and are designed for dynamic sealing applications. - Zhejiang Jiacheng says Quad Rings are used in reciprocating, shaft-swinging, rotating and helical-motion sealing. - ED Seal Rings are used in pneumatic and hydraulic joints, including pipe joints, hydraulic plugs and transition joints. - The O-ring lineup includes NBR, FKM, EPDM, silicone, fluorosilicone, FEPM, PTFE and FFKM, depending on the product and application. - Standard and customized O-ring sizes are available. - Standard specifications include AS568, JIS B 2401 and DIN 3771. - The company says it has experience in seal mold development and can design and manufacture special and complex seals for customized requirements. - Zhejiang Jiacheng reports more than 100 sets of production and testing equipment, professional experimental facilities and an ERP management system. - The company obtained IATF 16949 quality management system certification in 2019. - A dedicated R&D center went into use in 2024 and was recognized as a Zhejiang Provincial R&D Center.

Between the lines: - The product mix points to a strategy built around technical fit rather than commodity sales. - Material choice is central in sealing, so a broad elastomer range helps Zhejiang Jiacheng serve more industries and operating conditions. - The company’s emphasis on customization suggests it is targeting OEMs and industrial customers that need seals matched to specific machinery, not off-the-shelf replacements.

What's next: - Demand for seals is likely to keep rising as machinery becomes more compact, automated and performance-driven. - Zhejiang Jiacheng appears set to lean further into R&D, testing and custom development as buyers ask for tighter performance targets. - The company’s international footprint may also matter more as equipment makers continue sourcing components across borders.

The bottom line: - Zhejiang Jiacheng is betting that the future of sealing belongs to manufacturers that can combine material expertise, precision production and customization.
