Leading manufacturer of high-precision industrial seals. Specialized in custom NBR, FKM, EPDM, Silicone, NR, and HNBR components. Engineering-grade sealing solutions for global industries.
Product introduction
In critical industrial applications, the integrity of a seal defines the performance of the entire system. We specialize in the manufacturing of high-precision sealing components tailored to withstand extreme pressures, corrosive chemicals, and fluctuating temperatures.
From standard O-rings to complex bespoke gaskets, our multi-material expertise ensures that your equipment operates with maximum efficiency and zero leakage.
Material Expertise: Choosing the Right Elastomer
Selecting the correct material is vital for the performance of your application. We offer a wide range of high-grade polymers:
1. NBR (Nitrile Butadiene Rubber)
Characteristics: Excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. Good mechanical properties and high abrasion resistance.
Operating Temperature: -40°C to +120°C (-40°F to +248°F)
Common Uses: Fuel system seals, oil gaskets, hydraulic hoses, and general-purpose industrial O-rings.
2. FKM (Fluoroelastomer)
Characteristics: Exceptional resistance to high temperatures, ozone, oxygen, mineral oil, and synthetic hydraulic fluids. Extremely low gas permeability.
Operating Temperature: -20°C to +250°C (-4°F to +482°F)
Common Uses: Aerospace seals, chemical processing equipment, high-vacuum systems, and heavy-duty automotive engine gaskets.
3. EPDM (Ethylene Propylene Diene Monomer)
Characteristics: Outstanding resistance to weathering, ozone, UV, and steam. Excellent electrical insulation and resistance to polar solvents (ketones, alcohols).
Operating Temperature: -50°C to +150°C (-58°F to +302°F)
Common Uses: Automotive cooling systems, window and door seals, outdoor electrical enclosures, and pharmaceutical gaskets.
4. Silicone (VMQ)
Characteristics: Superior thermal stability and flexibility at low temperatures. Non-reactive, odorless, and available in food-grade (FDA/LFGB) and medical-grade variants.
Operating Temperature: -60°C to +230°C (-76°F to +446°F)
Common Uses: Food and beverage processing, medical device components, electronics insulation, and high-heat kitchenware.
5. NR (Natural Rubber)
Characteristics: High tensile strength, superior resilience, and excellent resistance to tear and fatigue. Best-in-class elasticity.
Operating Temperature: -50°C to +80°C (-58°F to +176°F)
Common Uses: Vibration isolators, engine mounts, heavy-duty industrial rollers, and shock-absorbing components.
6. HNBR (Hydrogenated Nitrile)
Characteristics: Enhanced mechanical strength and heat resistance compared to standard NBR. Highly resistant to modern fuel additives and sour gas.
Operating Temperature: -40°C to +160°C (-40°F to +320°F)
Common Uses: Oil field packers, automotive timing belts, and high-stress marine sealing systems.
Our Customization Capabilities

Advanced Manufacturing: Utilizing high-precision injection molding, compression molding, and CNC cutting to ensure tight tolerances.
Global Supply Chain: We serve clients across Europe, North America, and Asia, ensuring timely delivery and compliant documentation .
Technical Support: Our engineers assist in the design phase to optimize part geometry and material selection, reducing your long-term costs.
FAQ
Q1: How do I choose between NBR and FKM for oil sealing?
A: NBR is cost-effective for standard oils up to 120°C. If your application involves temperatures above 120°C or aggressive chemical additives, FKM is the superior choice due to its high-temperature stability.
Q2: What is the lead time for custom-molded parts?
A: Tooling and sample production typically take 15 working days. Once samples are approved, mass production usually takes 1-3 weeks depending on the order volume.
Q3: Can you provide material test reports?
A: Yes. We provide Material Test Reports (MTRs), including tensile strength, elongation at break, and hardness verification .
Q4: Do you support custom logo molding?
A: Absolutely. We can integrate your logo directly into the mold design or apply it via high-precision laser marking for permanent identification.
Q5: Can I get a sample before placing a bulk order?
A: Yes, we offer prototyping services and sample runs to ensure the component meets your exact specifications before proceeding to mass production.
