Product Details

buna n rubber rings size

is from Yiho Polytek,which is a technology production enterprise integrating R&D, production and sales.

Advantage of buna n rubber rings size

• They seal over a wide range of pressure, temperature and tolerance.

• Ease of service, no smearing or retightening.

• No critical torque on tightening, therefore unlikely to cause structural damage.

Rubber O-rings normally require very little room and are light in weight.

• In many cases an O-ring can be reused, an advantage over non-elastic fl at seals and crush-type rubber gaskets.

• The duration of life in the correct application corresponds to the normal aging period of the O-ring material.

• When rubber seals failures,it is normally gradual and easily identified.

• Where differing amounts of compression effect the seal function (as with fl at gaskets), an buna rings is not effected because metal to metal contact is generally allowed for.

• They are cost-effective.It can save your cost refer to other rings with different material.

Good mechanical technological parameters.of buna n rubber rings size

high abrasion resistance,low gas 
permeability and good resistance to mineral oil based lubricating oils and greases,
hydraulic oils,highly non-flammable hydraulic fluids HFA,HFB,HFC,silicone oils and 
greases,water up to approx.80°C.NBR is generally not resistant to polar solvents,
glycol-based brake fluids and highly non-flammable hydraulic fluids HFD.It has a low
resistance to ozone ,weathering and ageing.
In most hydraulic applications this has no effect because the hydraulic seals are installed 
internally in the hydraulic components.


Application:NBR is frequently used in the hydraulic field due to its good mechanical 
characteristics and resistance to mineral oil based lubricating oils and greases.
