ISO 9001 Certified Precision Sealing Components with Multi-Material Expertise and Custom Hardness Range for Industrial Seals

Precision Sealing Components | Custom NBR, FKM, EPDM, HNBR & Silicone Seal

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.

For O-rings and custom gaskets, specify the gland or sealing-face dimensions, compression arrangement, movement and actual medium. Agree sample acceptance and any leak-test method for the complete assembly.

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: Confirm for selected compound, medium and exposure duration
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: Confirm for selected compound, medium and exposure duration
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: Confirm for selected compound, medium and exposure duration
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. Food-contact or medical requirements need the specified compound, applicable documentation and testing.
Operating Temperature: Confirm for selected compound, medium and exposure duration
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: Confirm for selected compound, medium and exposure duration
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. Review the exact compound for fuel additives and gas exposure; sour-service suitability requires application-specific qualification.
Operating Temperature: Confirm for selected compound, medium and exposure duration
Common Uses: Oil field packers, automotive timing belts, and high-stress marine sealing systems.

FAQ

Q1: How do I choose between NBR and FKM for oil sealing?
A: Compare the exact compounds against oil identity, additives, continuous and peak temperatures, movement and gland design. A single temperature threshold does not determine suitability.

Q2: What is the lead time for custom-molded parts?
A: Confirm tooling, sample approval and production timing after drawing, compound and quantity review.

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: Specify the logo or part-number position, size and legibility. Confirm molded identification or another suitable marking method on the approved sample.

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.
