1. Solid Factory Foundation & Large-Scale Production Capacity

Founded in 2013, Tebiete Rubber is a Hebei-based high-tech SME specializing in R&D, production and sales of all types of rubber seals, with a 20,000-square-meter modern production workshop located in Julu County, Xingtai City, Hebei Province.

The factory’s core technical team accumulates over 30 years of seal manufacturing experience, solving sealing leakage, mud intrusion and wear-resistance pain points for heavy-load equipment under harsh working conditions.

2. Full-Category Product Layout, Covering All Scenarios of Heavy-Duty Equipment

Unlike small workshops that only produce single-specification oil seals, Tebiete develops a complete product matrix targeting commercial vehicles, engineering machinery, agricultural machinery and mining equipment, covering mainstream OE standard specifications of global vehicle brands:

1. Heavy-duty truck hub oil seals: supporting Sinotruk, Shacman, FAW, MAN and other axle models, including three-lip mud-proof half-rubber half-iron oil seals and maintenance-free axle seal kits;

2. Crankshaft oil seals: NBR/FKM high-temperature resistant front/rear crankshaft seals for heavy truck engines;

3. Light & medium truck seals: matching Isuzu, JAC, Nissan UD and Japanese vehicle series transmission and rear axle oil seals;

6. Auxiliary rubber accessories: O-rings, shock-absorbing rubber parts, engine mounts, brake rubber diaphragms and other auto rubber components.

High-performance raw materials including NBR nitrile rubber, FKM fluororubber and AEM composite materials are adopted, enabling finished products to work stably within -40℃ to 200℃, with prominent oil resistance, wear resistance and anti-aging properties. Customized seals can be designed according to customers’ shaft diameter, operating temperature, pressure and contact medium.

3. Complete International Certifications, Strict Whole-Process Quality Control

Quality is the core evaluation standard for choosing a Chinese seal factory, and Tebiete has passed authoritative global management system certifications recognized by CNAS and IAF, eliminating buyers’ worries about product compliance:

• IATF 16949:2016 Automotive Quality Management System Certification (valid until July 4, 2027);

• ISO 9001 Quality Management System, ISO 14001 Environmental Management System, ISO 45001 Occupational Health & Safety Management System;

• SGS rubber material physical performance test reports for all core raw materials.

Every batch of products undergoes multi-link sampling inspection from raw material incoming inspection to finished product delivery, establishing a full batch traceability system. Products can adapt to severe working environments such as muddy mining sites, dusty construction sites and long-hour farm operations, effectively reducing equipment oil leakage and maintenance frequency.
