O-rings are essential sealing components across multiple
industries, effectively preventing leaks and maintaining system
performance in hydraulic, pneumatic, automotive, and industrial
applications. These versatile rings preserve seal integrity by
containing fluids and gases.
O-ring kits are extensively utilized in major industrial sectors,
featuring comprehensive assortments of standard-sized O-rings. Our
supply includes specialized O-ring kit boxes compatible with
leading excavator brands such as SANY, HITACHI, KOMATSU, DOOSAN,
HYUNDAI, KOBELCO, VOLVO, SAMSUNG, KATO, SUMITOMO, and DAEWOO.

What is NBR and Viton?
Two of the most commonly approved elastomers, Nitrile (popularly
referred to as NBR or Buna-N) and Viton® (Fluorocarbon rubber).
Both materials are a great choice for general industrial use, they
offer excellent compression set resistance and have a versatile set
of properties list of applications and properties.
Viton vs Nitrile in the durability category could be considered a
tie, but it depends on the application and external elements. In
summary, NBR seals are more durable in dynamic situations where
flexibility is important, and Viton seals are more resistant to
external elements and harsh conditions.
Nitrile Rubber
Temperature: Nitrile is effective within a temperature range of -30°C to 100°C.
General Suitability: Used for general purpose applications requiring resistance to
aliphatic hydrocarbons, petroleum oils, water and hydraulic fluids.
Environmental Properties: Nitrile vs Viton® is not resistant to degradation from weather and
ozone exposure. Designed to resist most oils and lubricants, more
importantly petroleum based lubricants, these seals have other
benefits, such as superior abrasion and tear resistance, making
them suitable for heavy duty industrial applications.
Applications: A cost effective product, that works well with constrained
temperatures and chemical resistance.
Viton® Rubber
Temperature: Viton® seals can withstand temperatures up between -20°C to 210°C.
Viton® seals are prone to failure below -15°C in dynamic
applications, as they become inflexible and hard.
General Suitability: Viton® is best suited for diverse sealing jobs that require high
temperature and chemical resistance. Applications involving contact
with petroleum oils, acids, silicone fluids and gases, halogenated
hydrocarbons (trichloroethylene and carbon tetrachloride), aromatic
hydrocarbons usually have seals and o rings made of Viton®.
Environmental Properties: Viton® O-rings and seals have a wide range of chemical resistance
(involving mineral acids, fuels, and oils) and this material is
also highly resistant to oxidation, UV exposure, fungus, weather,
ozone, and mould. This makes Viton® far superior to Nitrile in
these regards. They are also designed to resist most oils and
lubricants, more importantly petroleum-based lubricants.
Applications: Viton® functions well in different automotive, chemical and
appliance-processing industries.
Cost: As an approximate guide, Viton® compound is ten to fifteen
times more expensive than NBR. However, we stock both NBR and Viton
O-rings and seals AS/BS, metric, French, German and other metric
series at Polymax.
What is the difference between NBR and HNBR O-rings?
In comparison with NBR, HNBR has better abrasion resistance, tear
resistance, high-temperature properties and resistance to chemical
attacks.
