--- Why Choose Xingtai Haoyuan Seals? ---

• Expertise in Rubber Seal Manufacturing:

Since its establishment in 2017, Xingtai Haoyuan Seals Co., Ltd. has built a solid reputation as a trusted name in the rubber seal manufacturing industry, particularly in North China. Rooted in Renze District, Xingtai, the company leverages decades of technical heritage from its predecessor specializing in axle seals, enabling it to deliver cutting-edge solutions in fluororubber and high-performance sealing technology.

• Custom O-rings and Gaskets:

At Xingtai Haoyuan Seals, we specialize in the design and manufacture of custom O-rings and gaskets tailored to exact engineering specifications. Whether you need standard sizes or complex geometries, our team works closely with customers from initial drawing design through material selection, production, and final testing. Each batch undergoes 100% air tightness testing, ensuring zero defects before shipment. One notable case involved a power equipment manufacturer in Henan who required a custom fluororubber O-ring for a high-voltage transformer sealing system operating in harsh industrial environments. The original supplier’s product failed after just three months due to degradation from ozone exposure. Xingtai Haoyuan stepped in, using DuPont fluororubber and optimizing the compound formulation to resist ozone and thermal stress. The result? A seal that lasted over two years without maintenance, significantly reducing downtime and repair costs. We also offer customization based on international standards such as DIN, JIS, and ASME. Our product range includes not only standard O-rings but also profiled gaskets, spiral wound gaskets, and multi-layer sealing components suitable for chemical processing, oil & gas, and HVAC systems. With our own production facilities and supply chain control, we guarantee spot availability for common items and on-time delivery for custom orders—even for bulk quantities. Our commitment to precision and adaptability ensures that every O-ring and gasket we produce meets the highest performance expectations, making us a go-to supplier for manufacturers seeking dependable, cost-effective sealing solutions.

• High-Performance Oil Seals:

Xingtai Haoyuan Seals Co., Ltd. excels in producing high-performance oil seals engineered for extreme working conditions. These seals are critical components in automotive engines, construction machinery, and industrial gearboxes, where leakage prevention and longevity are paramount. Our oil seals are manufactured using high-grade fluororubber and nitrile compounds sourced from reputable suppliers like DuPont and ExxonMobil, ensuring superior resistance to oil degradation, heat, and mechanical wear. A standout example comes from a major heavy-duty truck OEM in Shandong, which faced recurring oil seal failures in their rear axle assemblies due to high torque and temperature fluctuations. After switching to Xingtai Haoyuan’s custom-designed oil seals—featuring a dual-lip structure and reinforced steel cage—we observed a 98% reduction in field returns within the first year. The seals maintained integrity even after 150,000 km of continuous operation under severe conditions. Furthermore, our ability to customize dimensions, lip profiles, and material blends enables us to address unique challenges such as vacuum environments or aggressive chemical exposure. All oil seals are produced under strict ISO9001 and IATF 16949 compliance, with traceable quality records and full documentation. We also provide technical support during installation and performance monitoring. With a dedicated R&D team and rapid prototyping capabilities, we can develop new seal designs in under 15 days. This agility, paired with our proven track record in delivering durable, high-efficiency oil seals, positions Xingtai Haoyuan as a strategic partner for manufacturers aiming to enhance equipment reliability and reduce lifecycle costs.
