Oil Resistant Rubber Gasket Quality Control
Raw Material & Compound Inspection
Rubber materials and compounds are checked against the approved material requirements before production to help maintain consistent oil resistance, hardness, and physical properties between production batches.
Dimensional Inspection
Critical dimensions such as inner diameter, outer diameter, thickness, holes, profiles, and sealing surfaces are inspected against approved drawings, samples, and specifications.
Physical & Performance Inspection
Relevant properties such as hardness, tensile strength, elongation, compression set, and media resistance can be evaluated according to the approved specification and product requirements.
Batch Consistency & Traceability
Production specifications, approved materials, and inspection requirements can be controlled across repeat orders to reduce variation between batches.
Technical Documentation
Documentation and technical inspection records can then support specification approval, incoming inspection, and repeat procurement.

FAQ
Q: What Causes Oil Resistant Rubber Gaskets to Swell or Harden?
A: Gasket swelling, hardening, or cracking can result from incompatible fluids, excessive temperature, aging, or unsuitable rubber compounds for the actual service environment.
Q: How Can I Improve the Service Life of an Oil Resistant Rubber Gasket?
A: Proper material selection, controlled compression, suitable installation, and operation within the approved temperature and pressure range can help extend gasket service life.
Q: Are Oil Resistant Rubber Gaskets Suitable for Hydraulic Oil?
A: NBR, HNBR, and FKM can be used with different hydraulic fluids, but compatibility should be verified against the specific fluid grade, additives, temperature, and operating conditions.
Q: Can Oil Resistant Rubber Gaskets Be Used for Fuel Systems?
A: Yes, NBR and FKM are commonly used for fuel-related sealing, with the appropriate compound selected according to the fuel type, temperature, and exposure conditions.
Q: What Gasket Hardness Is Suitable for Oil Sealing?
A: Common hardness selections range from Shore A 55–75 for NBR, 70–90 for HNBR, and 65–85 for FKM, with the final hardness matched to the sealing interface and compression requirements.
Q: Can Oil Resistant Rubber Gaskets Be Supplied in Different Shapes?
A: Yes, gaskets can be manufactured in flat, ring, flange, die-cut, and other profiles according to the required sealing geometry and production method.
