Resources
Our Red Thread™ IIA piping systems are UL-971 listed for all UL-identified applications and fuels, including alcohol and alcohol-gasoline mixtures of either ethanol or methanol up to and including 100%. The piping system is compatible with biodiesel and E85 fuels.
Red Thread IIA Series piping costs 63% less than 2-in. coaxial flexible pipe and 46% less than 1½-in. coaxial flexible pipe. Red Thread IIA Series piping also costs 20% less than Red Thread IIA traditional/parallel layout piping.
30-year warranty
With more than 50 years of proven performance in the marketplace, UL-971 Listed Red Thread IIA pipe, fittings, and adhesive carry a 30-year warranty. The product is warrantied to be free from defects in material and workmanship and against internal and external corrosion when used for underground transportation of fuels.
Leak prevention
UL-971 bonded sump entry fittings provide a positive seal at the sump, preventing leaking of underground fuel in or out of the sump. Our Bonded Sump Entry Fitting–Termination Style also provides Class I protection, which complies with California’s requirement for continuous interstitial monitoring of the piping systems’ secondary containment.
StationWare 3000
StationWare 3000 is a standalone CAD program that provides a professional-looking station layout drawing and an accurate bill of materials for the site.
Secondary Containment
When secondary containment is needed, Red Thread IIA provides a true pipe-in-a-pipe system. Containment pipe is identical to the primary pipe. Sections are joined together with matching two-piece clamshells that are bonded and bolted together. One-half of the clamshell fitting is prefitted with female-threaded fasteners to make assembly fast and easy from one side of the fitting.
