Wear Resistant Shock Oil Seal with Long Service Life

Our oil seals incorporate specially formulated rubber compounds with optimized hardness (Shore A), a reinforced internal frame structure, and advanced anti-fatigue additives. Combined with precision manufacturing tolerances of ±0.05 mm and multi-stage quality inspection, these design features deliver significantly better abrasion resistance and longer service life compared to standard commercial-grade seals. The specially designed cord reinforcement also maintains dimensional stability under sustained load and high-speed rotation.

Absolutely. Our production capacity of 500,000 pieces per month, supported by advanced hot pressing, injection molding, and extrusion equipment, enables us to fulfill both small-batch and high-volume orders with consistent quality and on-time delivery. Typical lead times are 15–25 days depending on order quantity and specification complexity. Our well-established material procurement channels ensure stable raw material supply even during peak production periods.

NBR (Nitrile Rubber) offers excellent oil resistance and good mechanical properties at a competitive price — ideal for standard automotive shock absorbers. FKM (Fluorocarbon/Viton) provides superior chemical resistance and high-temperature performance (sustained 200°C+) for demanding applications. Silicone excels in extreme temperature ranges (−60°C to 350°C) and offers excellent ozone/UV resistance for outdoor use, though with lower mechanical strength. EPDM is preferred for brake fluid and weather-resistant applications. We can recommend the optimal material based on your specific fluid type, temperature, and pressure conditions.

Yes, we provide 1–2 pieces of free samples for your evaluation and fitment testing. Sample lead time is approximately 25 days, during which we manufacture your seals exactly to your provided drawings or physical samples. This allows you to verify dimensional accuracy, material properties, and installation compatibility before committing to mass production. For customized designs, we can also produce prototype tooling for sample validation.

Our quality management system is certified to ISO 9001:2000 and IATF 16949:2016 automotive standards. We implement incoming raw material inspection, in-process quality checks at each production stage, and 100% final inspection of dimensions and visual defects before shipment. Our testing laboratory is equipped for material composition analysis, hardness testing, dimensional measurement (to ±0.05 mm), and performance validation. Material certifications and inspection reports are available upon request for every production batch.

We accept T/T (Telegraphic Transfer), Western Union, PayPal, and L/C (Letter of Credit) to accommodate different customer preferences. All shipments use standard export-grade packaging designed to protect oil seals from damage, moisture, and contamination during international transit. Prices are negotiable based on order volume, material specification, and product complexity. For any shipping or logistics inquiries, our customer service team is available to assist with arrangement details.

Yes, we fully support OEM and ODM customization including custom logos, branding, and colors matched to any Pantone reference. We can also customize material formulations, hardness grades (Shore A), conductivity properties (conductive or insulative), and packaging/labeling to your specifications. Simply provide your requirements, and our engineering team will propose the optimal manufacturing solution — whether based on your existing drawings, physical samples, or a new design concept.
