Installation & Assembly of "GE" Coupling

  1. Ring, housing and  bolts, ready for assembly  -a spanner is  the only tool  needed.     2. Thoroughly lubricate Inside and outside of rubber ring with Vegetable based lubricant. This avoids pinching or nipping of the ring. Recommend use of ‘NMC’ Lubricant.
  3. Slip the ring over one pipe and bring both the pipe ends together.     4. Slide the ring into central position over the pipe ends.
  5. Put on the sections of the housing and insert the bolts and nuts.     6. Bolt up evenly until the nuts are fully tightened.
Ensure that the bolt sections of the half housings meet, metal to metal.
