Liner End Seal from PrimeLine Products
Get the watertight properties you need with seals created using reliable technology. This is the level of quality you can expect when you trust PrimeLine Products, the leading trenchless rehabilitation equipment provider. For more than 20 years, we’ve been proudly maintaining the highest quality when it comes to product standards.
The CIPP end seal assures you of a watertight seal at the ends of CIPP sections using the same reliable sealing technology that has made NPC the world’s leading supplier of pipe-to-manhole connectors.
A liner end seal is designed to seal the end of a rejuvenated pipe that has been cured in place. These products prevent the transfer from/into the end portion of the liner. Our unique end seal features include patented slotted expansion bands from NPC, the world’s top provider of pipe-to-manhole connectors. The end seal we offer is easy to install and designed with optimal durability in mind.
Available in an assortment of diameters and in two widths and usable on new and existing pipe structures, our selection of NPC joint seals and manhole seals also includes:
- Internal joint seals that prevent water from getting into underground pipes.
- External pipe joint seals that prevent infiltration around pipe joints and manholes with these seals, which include flexible rubber seals.
- Flexrib frame – chimney seals, which can be used to create a watertight seal between the top of manhole cones and the frame casting.
Meeting the ASTM C923 Watertightness Specification, our CIPP end seal includes a patented NPC Slotted expansion band that provides the additional sealing force. Pipe diameter reduction is also kept to a minimum. The exclusive design of this seal creates a permanent mechanical watertight seal. The spring-rubber interaction also produces an audible click to confirm that the seal has been created.
A top-quality liner end seal is beneficial because it reduces the risk of liner deterioration from groundwater. What this ultimately does is increase the odds that interior coatings will properly adhere to inside pipe surfaces.
All of our NPC joint seals and manhole seals are designed with quality and reliability in mind. Many of the design features are based on patented technology. This gives you the advantage of being able to offer advanced sealing protection to your customers.
The CIPP End Seal utilizes the NPC patented slotted expansion band to provide the maximum sealing force with a minimum reduction in pipe diameter. This unique design captures the rubber and compresses it against the existing pipe and new CIPP liner creating a permanent mechanical watertight seal.
The patented NPC Slotted Band is constructed from a single piece of 300 series Stainless Steel precisely rolled to match the diameter of the CIPP liner. The band is then expanded using a hydraulic expansion tool. As the band expands the integral latching mechanism progresses from slot to slot, positively locking on each one until the next one is reached. There is an audible click created by the spring/rubber interaction as the band is expanded into place. The unique shape of the slotted band provides the maximum amount of strength and sealing force with the least possible thickness.
