Low Friction Chemical Resistant Shock Oil Seal for Harsh Working Conditions

This heavy-duty shock absorber oil seal is purpose-built for demanding environments where chemical exposure, extreme temperatures, and high friction would compromise standard seals. Available in multiple elastomer compounds including NBR, FKM, PTFE, HNBR, VMQ, and custom formulations, it delivers reliable sealing performance across a -60 degree C to 350 degree C temperature range. Manufactured under IATF16949:2016 and ISO9001:2000 quality systems, each seal is engineered for precision fit and long service life in automotive, industrial, and off-highway applications.

Q: How do I select the right material for my application?

Refer to our Material Selection Guide above. For automotive shock absorbers with standard oil exposure, NBR offers the best cost-performance balance. For extreme chemical environments, PTFE or FKM is recommended. For wide temperature swings (-60 to 225C), VMQ (silicone) excels. Our engineering team can assist with material selection based on your specific fluid type, temperature range, and pressure requirements.

Q: What is the minimum order quantity?

Our standard MOQ is 50 pcs for catalog items. For custom-designed seals, we accept as low as 1 pc for trial and prototyping purposes. Volume pricing applies for orders above 1,000 pcs.

Q: Can you produce seals from my drawings or samples?

Absolutely. We specialize in custom OEM and ODM production based on customer-provided drawings, 3D models, or physical samples. Our engineering team will reverse-engineer your sample or work from your CAD files to produce a precise reproduction.

Q: What certifications do you hold?

We are IATF16949:2016 certified for automotive quality management and ISO9001:2000 certified for general quality systems. Our materials carry ROHS and FDA compliance where applicable, ensuring suitability for regulated markets.

Q: How long does delivery take?

Standard delivery time is 15-25 days depending on order quantity. For urgent requirements, expedited production can be arranged. Small quantity samples ship via DHL/FEDEX/UPS/TNT (3-7 days), while bulk orders ship via sea or air freight.

Q: Do you provide free samples?

Yes, we offer 1-2 pcs of free samples for quality evaluation. Customers only need to cover the shipping cost. This allows you to verify material, dimensions, and performance before committing to a production order.

Q: What tolerance can you hold?

We maintain a tight manufacturing tolerance of +/-0.05mm across all production methods (hot pressing, injection molding, and extrusion). Our density control range is 1.0-2.0g/cm3 with consistent batch-to-batch verification.

Q: Can you match a specific color or hardness?

Yes. We can match any Pantone color for your seals and offer a full range of Shore A hardness values. Whether you need black for UV resistance, transparent for visual inspection, or color-coded seals for assembly identification, we have you covered.
