EPDM Boss O-Rings
These EPDM boss o-rings are manufactured from FDA/NSF grade sulfur-cured EPDM rubber, designed specifically for use in straight-thread boss-type hydraulic fittings. They are engineered to seal against phosphate ester-based fluids, water, steam, and brake fluids, but are not compatible with petroleum oils or fuels due to swelling risks. The o-rings are intended for integration into pumps, valves, cylinders, and motors where chemical resistance and environmental durability are critical.
The material choice reflects industry-standard EPDM properties: excellent ozone and UV resistance, stable performance between -40°C and 120°C, and good compression set resistance. Sulfur curing is selected over peroxide curing for improved tear strength and wear resistance, making these seals more durable in dynamic applications. The hardness is typically 90 Shore A, consistent with common boss seal requirements, though exact tolerances should be confirmed with the supplier.
Buyers in hydraulic equipment manufacturing, industrial maintenance, and automotive repair commonly source these seals for replacement or OEM assembly. Packaging is typically bulk in polybags or cartons, with no MOQ stated. Lead time is not specified; buyers must request confirmation. Trade terms are not listed, but standard FOB or CIF terms from Jiangsu ports are typical for this origin.

| Typical Tolerance | Standard dimensional tolerance of ±0.1 mm for cross-section, per ISO 3601-1 |
| Typical Compression Set | Typical compression set at 70°C for 22 hours under 25% deflection is ≤25%, per ASTM D395 |
| Typical Shelf Life | Standard storage life of 5 years when kept in original packaging, away from UV and ozone sources |
| Packaging | Bulk polybag or carton; no packaging details confirmed by supplier |
| Certification | Material claims FDA/NSF compliance; no certificate documents provided or verified |

Sourcing EPDM Boss O-Rings from Danyang Gangwei New Materials Technology Co. Ltd. - China Import Guide
Before ordering, verify the material certification for EPDM compliance with FDA/NSF standards, especially if used in food, water, or pharmaceutical systems. Request batch-specific test reports for compression set, fluid resistance, and hardness. Confirm that the o-rings are sulfur-cured, not peroxide-cured, as this affects durability under mechanical stress. Do not rely on supplier claims without documented proof.
Lead time and incoterms are not stated. Buyers must request confirmation of production cycle, shipping port, and whether terms are FOB Shanghai, Ningbo, or another Jiangsu port. Payment terms are typically 30% advance, 70% against copy of B/L, but this varies. Confirm packaging type and labeling requirements, especially for export compliance and customs clearance.
Inspect incoming shipments for dimensional accuracy, surface defects, and correct material composition. Request a sample from each batch for hardness testing and fluid immersion tests. Verify packaging integrity and labeling with product code and batch number. Retain samples for potential failure analysis. Document all inspection results and retain them for quality traceability.
