Polieco: design and production of high-density polyethylene jointing couplers, elastomeric seal for manholes and other polyethylene special components (branches, elbows).
Jointing couplers to connect two polyethylene corrugated pipes. The connection between hdpe pipes is very easy. For a quick connection between pipe and coupler is recommended the lubrication of the internal part of the coupler and the insertion of elastomeric seals.
On the site you can see some photos showing workers connecting two slotted pipes with jointing couplers.
