Oring Nbr O-Ring Fkm Rubber Seal

O-ring is a type of rubber seal with a round cross-section, which is also called O-ring because its cross-section is O-shaped. It began to appear in the mid-19th century, when it was used as a sealing element for steam engine cylinders.

Product Introduction

Advantage

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

• No smearing or retightening required.

• There is no critical torque when tightening, thus structural damage is unlikely.

• O-rings typically take up little space and are low in weight.

• Unlike non-elastic seals and crush-type gaskets, an O-ring can often be reused.

• The life span in the correct application corresponds to the O-ring material's normal aging time.

• O-ring failure is typically gradual and easily detectable.

• Where varying degrees of compression affect the seal function (as with fl at gaskets), an O-ring is unaffected because metal to metal contact is normally permitted.

• They are inexpensive.
