Check out Bentley-Harris. They are specialists in piping and tubing
protection. The UK facility is in Rochdale, England. I installed special
fire and insulation sleeving on N111EU during the build process and have
never had a problem with vapor locking (750HRS) in the most severe
conditions in the great South West US.
