FlexWorks Loop System™
The Industry's First Plug & Play Underground Fueling System
The patented OPW Loop System™, represents the state of the art in a completely integrated, environmentally secure underground fuel delivery system. The system, by design, employs pre-fabricated, factory assembled components, translating into dramatically less field labor and lower associated cost and potential for installation errors. The installed product preserves total underground access to all piping connections, piping runs and containment sumps for hassle-free inspection, maintenance or repair without ever having to excavate or even remove a dispenser. The Loop System™ incorporates field-proven OPW technology into a simplified, completely integrated piping system design that facilitates easy inspection, identification and repair of any problem that may develop and enhances the capability for leak prevention.
Red Thread IIA
Fiber Glass Systems is the market leader for underground fuel piping systems with almost 50 years of continuous supply of UL Listed products. Red Thread IIA piping is reliable and never been removed because of thus there are no reinstall costs. Our products are designed to meet governmental environmental regulations including EPA.
Advanced performance capabilities of DUALOY 3000/LCX offer a substantial cost control, and most importantly meet the safety and compliance needs. The unique coaxial construction of DUALOY 3000/LCX offers many features and makes this fiberglass pipe the best value in corrosion resistant piping solutions. High strength and stiffness make DUALOY 3000/LCX virtually indestructible, offering predictable and reliable performance. Its compact design allows less trenching and takes less warehouse space.
Dualoy 3000/L piping systems are made of fiberglass reinforced, aromatic amine cured, rigid, thermosetting epoxy resin. This pipe is manufactured using a unique process where 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.
