Register here Sign inDualoy™ 3000/L piping systems are made of fiberglass-reinforced, aromatic amine-cured, rigid, thermosetting epoxy resin. This pipe is manufactured using a unique process by which a continuous cylinder is generated with the fibers oriented more near the circumferential and axial directions than with the reciprocal process. Dualoy 3000/L also includes a pure resin liner.
Fiber Glass Systems is the market leader for underground fuel-piping systems, with almost 50 years of continuous supply of UL-listed products. Dualoy 3000L piping is reliable and has never been removed because of fuel incompatibility; thus, there are no reinstall costs. Our products are designed to meet governmental environmental regulations, including those of the US Environmental Protection Agency (EPA).
Leak prevention
UL-971 bonded sump entry fittings provide 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.
