FKM75 Rubber Seal | Molded Rubber Gasket | High-Temp
Chemical-Resistant Seal Product Description
This molded rubber seal is a high-performance component made of
FKM75 (Viton) material, sized 37.5x14.5x10.32mm. Engineered for
extreme conditions, it maintains reliable sealing performance
between -20°C and 200°C, with exceptional resistance to acids,
alkalis, solvents, and petroleum-based fluids. Its black,
rectangular design with three integrated posts/holes ensures
precise alignment in mating assemblies, creating a tight barrier
against fluid leakage while absorbing mechanical vibration. The
FKM75 material offers superior anti-aging and compression set
resistance, making it ideal for critical sealing applications in
chemical processing, automotive engines, and industrial hydraulic
systems.

Advantages- Extreme Temperature & Chemical Resistance: FKM75 withstands -20°C to 200°C and resists most aggressive
chemicals, acids, and oils, outperforming standard NBR rubber.
- Optimized Hardness & Elasticity: The 75 Shore A hardness formula balances structural stability and
sealing flexibility, maintaining integrity under dynamic pressure.
- Anti-Aging & Durability: Resists ozone, oxidation, and compression set, extending service
life by 2–3 times compared to conventional rubber seals.
- Precision Alignment: Three integrated posts/holes ensure accurate positioning in
assemblies, reducing installation errors and improving sealing
reliability.
- Vibration Damping: Molded structure absorbs mechanical vibration, minimizing noise
and wear in industrial and automotive equipment
Applications:- Seals chemical reactor flanges and pipeline connections to prevent
leakage of corrosive media, ensuring workplace safety.
- Provides high-temperature sealing in automotive engine
turbochargers and exhaust systems, protecting against heat and oil
degradation.
- Damping and sealing hydraulic system valve blocks, maintaining
pressure stability and reducing operational noise.
- Secures industrial machinery enclosures, creating a dust and
moisture barrier to protect internal components.
- Ensures leak-proof performance in fuel systems of new energy
vehicles, resisting hydrogen and coolant corrosion.
