Xingtai Heheng New Material Technology Co., Ltd. (shortened as Heheng Technology) is based in Renze District, Xingtai City, Hebei Province, China. Rooted in the mature, well-established rubber & plastic sealing industrial cluster locally, we are a professional service provider focused on sealing technology solutions for industrial equipment and automotive sectors.

Operating our own brand ‌vitalseal‌, we are technology-driven, integrating high-quality regional manufacturing resources to build a full one-stop supporting system covering R&D & selection, off-the-shelf supply, non-standard customization and after-sales support.

Deeply Rooted in Industrial Equipment, Serving Diverse Scenarios

We precisely target three core application scenarios: hydraulic cylinders, agricultural machinery and mining equipment. Through deep collaboration with multiple production enterprises, we have formed a flexible, highly efficient supply chain system.

Our full range of sealing products covers NBR Nitrile, PU Polyurethane, EPDM, FKM Fluoroelastomer, PTFE spring energized seals and more. We keep standard models of Step seals, Glyd rings, skeleton oil seals, O-rings, combined seal washers and other items in stock, and also accept non-standard custom orders for special FKM shaped parts, PTFE spring energized seals and other customized products. Our items are fully compatible with mainstream general equipment in the market, including agricultural machinery, engineering cylinders and mining hydraulic supports. Our business covers four major segments: spot wholesale, direct end-user supply, hardware channel agency and industrial & mining maintenance supporting, to meet diversified procurement demands from different customers.

Technology Empowered Sales, Solving Customer Pain Points

Our core highlight is "proactive technical support". Our experienced working condition selection team, with decades of expertise in the sealing industry, has deeply integrated on-site working condition experience with data models to build an AI-powered intelligent seal selection assistant system.

We provide customers with free services including working condition-based seal selection, equipment oil leakage fault diagnosis, groove dimension design optimization and overall sealing system solutions. Strictly following national production standards, we tightly control critical parameters such as temperature resistance, pressure resistance and medium compatibility, effectively solving long-standing industry pain points like wrong selection, frequent leakage and long non-standard order lead time. This ensures customers get reliable products that "fit perfectly, perform durably and cut total cost".

Dual-track Expansion: Industrial & Automotive Sealing

While consolidating our industrial and agricultural machinery supporting market, we have made key moves to expand our automotive sealing business, covering vehicle oil seals, suspension seals, powertrain seals and other segments. Leveraging our proven technical accumulation and strict quality control system, we deliver high-quality supporting solutions for automotive component manufacturers and the aftermarket. The ‌vitalseal‌ brand is steadily building reputation in both industrial and automotive sealing sectors, winning customer trust with consistent quality and rapid response.

Heheng Technology, rooted in the local industrial foundation, guided by our brand and empowered by technology, is committed to being your trusted professional supporting partner in both industrial and automotive sealing fields.
