Component Specifications

Definition
Sealing gaskets are precision-engineered components designed to create a leak-proof seal between mating surfaces in high-pressure oil filter cartridges. They function by filling microscopic irregularities between surfaces under compression, preventing oil leakage and maintaining system pressure integrity. These gaskets must withstand pressures up to 1000 psi, temperatures from -40°C to 150°C, and resist degradation from petroleum-based fluids and additives.
Working Principle
The sealing principle relies on controlled compression of elastomeric or composite materials between two rigid surfaces. When the filter cartridge is assembled and tightened, the gasket deforms to conform to surface imperfections, creating a continuous barrier. The sealing effectiveness depends on proper compression force, material resilience, and surface finish compatibility.
Materials
Nitrile rubber (NBR) for standard applications, Fluorocarbon (FKM/Viton) for high-temperature resistance, Polytetrafluoroethylene (PTFE) for chemical resistance, or composite materials with metal reinforcement for extreme pressure applications. Material hardness typically ranges from 70-90 Shore A.
Technical Parameters
  • Inner Diameter 50-200 mm (customizable)
  • Outer Diameter 60-220 mm (customizable)
  • Compression Set <20%
  • Pressure Rating Up to 1000 psi
  • Temperature Range -40°C to 150°C
  • Thickness Tolerance ±0.1 mm
Standards
ISO 3601-1, DIN 3770, SAE J515, ASTM D2000

Frequently Asked Questions

What is the typical service life of high-pressure oil filter gaskets?

Service life varies from 1-5 years depending on operating conditions, material selection, and maintenance intervals. Regular inspection during filter changes is recommended.

Can these gaskets be reused after disassembly?

No, sealing gaskets should never be reused. Compression set and material memory loss compromise sealing effectiveness after initial use.

How do I select the right gasket material for my application?

Consider operating temperature, pressure, fluid compatibility, and chemical exposure. NBR works for most standard applications, while FKM handles higher temperatures and aggressive fluids.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
