O-ring for installation on a variety of machinery and equipment, at a specified temperature, pressure,
and various liquid and gaseous media, at rest or in motion from the seal. On the machine, marine,
automotive, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery,
construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery,
and a variety of instruments, a large number of applications for various types of seals elements. O-ring is
mainly used for static seals and reciprocating seals. For rotational movement of the seal when limited to
low-speed rotary sealing device. O-ring is usually installed on the outer or inner circle from the seal section
is rectangular trench. O-ring seals still play a good shock absorption in oil, acid, wear, erosion and other
environmental chemistry. Therefore, O-ring hydraulic and pneumatic drive system most widely used a seal .

1,Oil-resistant, heat resistant
2,Dustproof and water proof
3,Durable
4,Excellent anti-chemical character.
5,Anti- compressibility function is very good.
6,Good ozone resistance ,aging resistance ,high/low temperature resistance,weather resistance etc.
Application:
Mechanical Sealing, Fixed Sealing, Shaft Sealing, Hole Sealing, Dust Prevention Sealing, Equipment
Sealing, Pump Sealing, Flange Sealing, Hydro sealing, Junction Surface Sealing and etc.
What are NBR O-rings?
Alongside FKM or HNBR, NBR (nitrile butadiene rubber) is one of the most frequently used elastomers
for sealing elements.
The material is characterized by advantageous mechanical properties and a broad resistance profile.
The wide range of applications for these O-rings is limited only by their restricted suitability for high
temperatures. But there is a solution for this too.
HNBR, hydrogenated nitrile butadiene rubber, extends the high-temperature range of NBR and is
therefore suitable for even more demanding applications. However, many standard applications can
be economically realized with NBR O-rings economically.
They are also known by manufacturer names such as Perbunan® or Europrene®.
The below two kinds o ring kit are also commonly used : (if you need other sizes ,we can make customized kits)
