At the ends, the Primus Line hose is connected to the existing pipe using Primus Line connectors. The high-pressure connector consists of a contoured inner tube and outer tube. The outer tube has a malleable steel jacket on the inside. A resin, which is injected through a valve on the outer tube, forces the steel casing and thus Primus Line® into the contours of the inner casing. So we obtain a durable, pull-proof connection.
After pressure-resistant sealing of the connector on the rehabilitated pipe section, a leak test is performed.
