Trenton Seal-Wrap is a casing end-seal wrapper consisting of a heavy woven glass coated with a butyl mastic of high dielectric quality wrapped around the end of the casing and on the carrier pipe. It is then strapped in place with stainless steel banding.
The Seal-Wrap system was designed by Trenton to enable field personnel to readily replace existing "rubber-boot" type end seals that are damaged prior to installation of casing filler. Seal-Wrap can also be used to reinforce existing "boot" or "compression" type seals. This system also has advantages for new construction applications. Seal-Wrap is a simple, efficient method of sealing the annular space between pipe and casing that does not necessitate absolute centering of the pipe in the casing.
