Floating Seal Materials

  • Author:Alice
  • Release on:2020-09-01
The effectiveness of fl oating seals is dependent on the
combination of tough materials used in a unique confi guration of the floating seal and the O-ring.


Floating Seal Seat Material
Special corrosion-resistant cast iron alloy

O-Ring Elastomer Materials
Nitrile (NBR)
Description: Commonly used because of its good
mechanical properties and low cost, standard nitrile
is also known as Buna-N. It has excellent resistance
to petroleum-based oils and fuels, water and alcohols.
Nitrile also has good resistance to acids and bases,
except those with a strong oxidizing effect.
Limitations: Avoid highly polar solvents (Acetone,
MEK, etc.) and direct exposure to ozone and sunlight.
Temperature Range: –50°C to 100°C
Hydrogenated Nitrile (HNBR)
Description: HNBR is obtained by partially or fully
hydrogenating NBR, leading to considerable improvement of the resistance to heat, ozone, and aging.
Temperature Range: –40°C to 120°C
Standard Fluoroelastomers (FKM)
Description: FKM compounds provide excellent
resistance to petroleum products and solvents,
delivering very good high-temperature performance.
Limitations: Avoid polar solvents, amines, anhydrous
ammonia, SKYDROL, hydrazine, and hot acids.
Temperature Range: –20°C to 200°C
Low Temperature Fluoroelastomers (FKM)
Description: Like the standard fl uoroelastomer, the
low-temperature compound has excellent resistance
to petroleum products and solvents, and very good
high-temperature performance; but in addition, there
is an extended low-end temperature advantage.
Limitations: Avoid polar solvents, amines, anhydrous
ammonia, SKYDROL, hydrazine, and hot acids.
Temperature Range: –40°C to 200°C
