HutlinerPacker® (Lateral connection packers) are inflatable hollow parts made from rubber and stainless steel with a protruding section, the rubber hat, which can be mounted on the side.
These special devices developed by Schwalm are used to press synthetic resin-saturated short liners onto couplings and cracks in the main pipe and hat section in connection joins.
The rubber hats, available in a variety of sizes, are connected to the HutlinerPacker® (lateral connection packer) using a screw thread. Lateral connection packers, with their flexible pipe bodies, can even be used in corner shafts.
The HutlinerPacker® (lateral connection packer) is a combination device which can be used with or without a rubber hat. If you take the rubber hat off, short liners can also be installed. With the rubber hat screwed on, they are used either as just the hat seal or as a combination of short liner plus hat seal = HutlinerPacker® (lateral connection packer).
