F-Series-D Termination

All-Fiberglass “Full Body” Fittings For DoubleWall Sumps

The F-Series “Full Body” line of DoubleWall entry fittings are a next-generation all-fiberglass design made to exceed California’s high standards. The F-Series is a bonded fitting that contains none of the common points of failure such as nuts, bolts, gaskets, clamps, boots, mechanical seals or sealants. The primary goal is to reduce the cost of maintenance for your fuel system to near-zero. A bonded piping system throughout ensures that the environment is kept safe from any contamination. Read more

Having a reliable penetration fitting for piping also means no water intrusion. The F-Series fittings are designed to bond to flat or curved-walled (separate models exist) fiberglass containment sumps only and can accommodate 3/4” and 1” electrical conduit as well as fiberglass pipe from 2” through 6” diameters including Ameron LCX coaxial pipe. All entry fittings for product pipe include dual test ports for monitoring the secondary pipe interstice. Fittings for conduit include communication holes so that the sump’s monitoring fluid will contact the exterior of the conduit. F-Series-D fittings are fully AB-2481 compliant and compatible with all conventional and alternative fuels. They are designed and UL tested for UL-971 specific piping applications. A new Adjustable variant is available that provides 0-10° degrees of angle adjustability. They retain their full warranty even when submerged in fuels: no fine print.
