1. Make sure that the gaskets are at an equal tension around the sleeve.
  2. Clean the joints of the pipes and fittings.
  3. Apply suitable lubricant to the ends of the pipe with elastomer seal. (Soap or cleaning solution, do not use oil-containing materials!)
  4. Place the cufflink on the pipe and push it in one go until you touch the ledge in the middle of the link.
  5. Slip the same into the pipe to be connected and push it into the fittings.
  6. A shovel can be used as a lever to help assemble the pit. A wooden board to be placed in the transverse direction of the pipe may also increase the pulling force.
  7. The fittings intended to be added can be connected with the necessary fasteners in advance and the final assembly is facilitated and accelerated.
