Benefits of Twisted O-Rings?

A twisted O rings is a doughnut, or torus designed seal usually utilised to avoid the passing of air or fluid. Simply put, O-rings are made use to keep fluid or air IN or OUT of a specified area.

Interlaced O-Rings are an excellent solution for numerous non-critical applications. Possibly, they might be the weakest at their glued or vulcanised joints. Its physical or commercial properties, which differ to some degree from the rest of the ring, can affect a seal’s dependability. A twisted or tired splice, as an example, can open up, producing failing, leakage as well as contamination problems.

Uniform moulding technology is recommended for usage in any huge diameter O-Ring groove where entwined, or serpentine shaped rings may provide integrity issues. It has applications in basically every market, consisting of aerospace, energy, oil chemical handling, and gas (EOG), semiconductor processing, industrial, and also lots of others.


  • Huge chambers, covers, vessels, containers, and doors where interlaced O-rings or serpentine rings present reliability issues
  • Vacuum cleaner, high stress and speciality semi-dynamic applications
  • Anywhere the stamina, as well as stability of uniform moulded rings, are essential for trusted seal performance

Functions & Advantages

  • Properties are consistent throughout the diameter of the ring
  • Easier, a lot more reputable instalment versus serpentine moulded O-rings
  • Decreased potential contamination of leak through interlaced joints
  • Material selections consist of standard HNBR, EPDM, NBR, and FKM products


Most of the times, O-rings are sized by the inside diameter after that by the cross-section or width. When you want an O-ring, you call it out by its size; you would offer the internal diameter first and then the cross section second. Such as this: 1.239 X. 070 inches. This is additionally how statistics of O-rings are called out. For example: 25.50 X 2.50. The reason for calling the internal diameter as opposed to the outside diameter is that the ID is what has the tolerance on it. The outside diameter is generally given as a reference just.
