Founded in 2013 in the Kunshan Economic and Technological Development Zone, Jiangsu Province, Telock Sealing has built its reputation over more than a decade on rigorous quality control, independent material R&D and responsive customer service. The company's products are exported to Europe, the Americas, Southeast Asia and many other countries and regions, serving as supporting components for numerous well-known domestic and international manufacturers.

A Complete Rubber Sealing Portfolio

Telock Sealing offers one of the most comprehensive product ranges in the industry, covering virtually every standard and custom sealing requirement. Its core catalog includes:

• Rubber O-rings — available in a wide spectrum of materials, sizes and hardness grades, from miniature precision dimensions to extra-large specifications;
• FFKM O-rings — perfluoroether seals engineered for extreme chemical resistance and high-temperature operating environments, ideal for semiconductor, chemical and pharmaceutical processes;
• ED Rings — pipe-fitting seals designed for reliable, leak-proof connections in hydraulic, pneumatic and fluid-handling systems;
• Rubber Washer — flat and custom-profile washers for sealing, spacing and vibration damping across industrial and consumer applications;
• Rubber Balls — precision-molded solid rubber balls used in valves, pumps, cleaning equipment and mechanical assemblies;
• Rubber Seals — a broad family including U-rings, Y-rings, rubber strips, retaining rings, high-pressure water seals, skeleton and plunger oil seals, polyurethane seals, PTFE washers and various special-shaped rubber parts.

Products are manufactured in materials including NBR, FKM, EPDM, silicone (SI), FFKM and PTFE, with hardness ranging from 40 to 90 Shore, enabling Telock to match the right compound to each customer's specific medium, pressure and temperature conditions.

Certified Quality and Material Compliance

Quality is embedded in every stage of Telock's operations. The company holds IATF 16949:2016 quality management system certification (issued by NQA) for the manufacture of rubber seals, underscoring its capability to meet automotive-industry quality standards. Its raw materials comply with ROHS 2.0, REACH, PAHS, FDA and UL testing requirements, and its seal rings have passed SGS testing against US FDA 21 CFR 177.2600 for total extractives — confirming suitability for food-contact and sensitive applications.

"Every seal we deliver — whether it's a standard Rubber O-ring, a chemically resistant FFKM O-ring, an ED Ring for pipe connections, a custom Rubber Washer, precision Rubber Balls or a specialized Rubber Seal — is engineered to perform reliably under the customer's exact working conditions," said Mr. Zhang Yunhe, founder of Telock Sealing. "Our independently developed sealing formulas achieve a 100% sealing-performance qualification rate, far exceeding industry benchmarks."

R&D, Automation and Customization

Telock Sealing operates a professional R&D team with modern R&D facilities, production equipment and testing instruments. The company independently develops core sealing formulas tailored to extreme conditions such as high and low temperatures and strong corrosion. Fully automated production equipment enables a daily output of tens of thousands of pieces with consistent precision, supporting both high-volume batch delivery and fast turnaround on custom orders.

A key differentiator is Telock's customization capability: the company designs tailored sealing solutions based on each customer's working medium, pressure and temperature, supporting non-standard sizes and special material requirements. Complementing production, the company has implemented an ERP system to enhance operational management and customer service, offering one-on-one technical support from pre-sales material selection through in-sales progress tracking and 24-hour after-sales response.

Broad Industry Applications

Telock's sealing products are widely deployed across hydraulic construction machinery, pipeline valves, high-pressure cleaners, water treatment equipment, electronics, photovoltaics, semiconductors, chemicals, automotive, marine, medical and cosmetic container industries — a breadth that reflects the versatility and reliability of its sealing solutions.

Looking Ahead

As global demand for precision, chemically resistant and application-specific seals continues to grow, Kunshan Telock Sealing Technology remains committed to advancing material science, expanding automation and deepening partnerships with customers worldwide. The company warmly welcomes distributors, OEMs and engineering partners to explore custom sealing solutions and long-term cooperation.
