Stretchable Structure

Knowing how stretchable your FEPM O rings are important during installation. These O rings should at least stretch 50%. When stretching, instead of stretching on just one side, perform it evenly for better results. To have an efficient seal, they should be connected comfortably to the groove.  For most applications, stretch is between 1% – 5%. We do not recommend stretch higher than 5%.

Their stretchable design is important for assuring the smooth operation of several vehicles, appliances, machines, and other devices. While a correct installation produces a reliable seal, it enables them to efficiently perform without leaks.

Tips for Installation

Here are some effective tips to help assure successful FEPM O-ring installation:

  • First, make sure the threads are lubricated. Because the shaft is threaded, the rubber seal is prone to tearing during setup. Use sticky tape or lubricant to conceal the threads and prevent tearing.
  • Enclose sharp corners. Despair in the o-rings can be caused by sharp lines, and even a small tear can break the seal.
  • Ensure to stretch FEPM o-ring uniformly to generate more durable final seals.
