NBR 200℃ Rubber Seal Ring
Large ship Sealing O ring Heat resistant anti-oxidation preservative Precision seal O rings
NBR O-rings
Size: AS568, ISO3601
Hardness: DURO 50~90 A, general 70/90 A
Color: general Black
Service temperature: -30°C~+120°C
NBR O-rings have excellent resistance to gasoline and fat hydrocarbon oil, and NBR O Rings have good heat resistance, good air
tightness, abrasion resistance and water resistance, strong cohesive force.
O-rings are suitable for installation on various types of machinery and equipment, and play a role of sealing under static or moving conditions under the specified pressure and temperature and in different liquid and gas media. Rubber O-rings are mainly used for sealing in static reciprocating motion.
Advantage
• 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.
• 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 gaskets.
• The duration of life in the correct application corresponds to the normal aging period of the O-ring material.
• O-ring failure is normally gradual and easily identifi ed.
• Where differing amounts of compression effect the seal function (as with fl at gaskets), an O-ring is not effected because metal to metal contact is generally allowed for.
• They are cost-effective.
