Flexible Connectors

for DEF/AdBlue®

FLEX-ING™ brand diesel exhaust fluid flexible connectors allow you to easily connect a pipework system to other systems components such as submersible pumps. Installers love their ease of installation while station owners have come to depend on their durability and how easy they make regular maintenance. The all-stainless steel construction provides complete compatibility with DEF (Diesel Exhaust Fluid)/AdBlue®. With tons of available options, Franklin Fueling Systems has the right connector to fit any application.

  • Highlights

     

    • The corrugated DEF/AdBlue® contact layers feature a 25% thicker metal construction and gain flexibility from having more corrugations per foot rather than thinner walls.
    • Enclosing the corrugated DEF/AdBlue® contact layer is a stainless steel braid that is manufactured from only high-grade stainless steel.
    • The EZ FIT union style coupling system is specifically designed to make connections in confined spaces simple and tight.
    • Each EZ FIT male and female union style coupling comes complete with couplers and gaskets.

  • Specs

    • All metal construction means one flexible connector for both above and below ground applications
    • An 18-8 alloy with titanium, 321 Stainless Steel inner core provides a long service life
    • Thick, schedule 80 hex end fittings protect against deformation of the ends
    • 100% pressure tested to assure quality
    • 50 Psi working pressure
    • EZ FIT clamp and gasket are included with each assembly
    • Stainless steel fittings and EPDM gaskets are fully DEF/AdBlue® compatible

    Ordering Guide

    DEF A X B C X D

    • DEF = DEF/AdBlue® Flexible Connector
    • All materials are fully compatible with DEF/AdBlue® including stainless steel fittings and EPDM seals.
    • A = Hose Diameter
    • 07 = ¾"
    • 10 = 1"
    • 15 = 1½"
    • 20 = 2"
    • 30 = 3"
    • B = Overall Length in Inches
    • Use two-digit format
    • C & D = End Fitting Options
    • EZ = EZ FIT flange only
    • EZM = EZ FIT male NPT (Each EZ FIT union style coupling comes complete with couplers and gaskets)
    • EZF = EZ FIT female NPT (Each EZ FIT union style coupling comes complete with couplers and gaskets)
    • M = Hex male fixed NPT
    • F = Hex female fixed NPT
    • BT = Hex male fixed BSPT
    • BTF = Hex female fixed BSPT
    • Example: DEF20X18MXEZM = DEF flexible connector, 2" hose diameter, 18" overall length, with one hex male fixed NPT fitting on one end and one EZ FIT male NPT fitting on the other (includes EZCLAMP and EZ20GASKET-EPDM).

    Flexible Connectors with Differing Hose and End Fitting Diameters

    All end fittings are, by default, the same diameter as the hose. If you require a flexible connector where the end fitting diameter does not match the hose diameter, the size must be indicated numerically in front of the corresponding fitting as in the example below.

    Rules:

    • End fitting diameters can not be smaller than hose diameters.
    • Only one hose fitting per flexible connector can be of a different diameter than the hose diameter.
    • End fitting diameter must only be one size larger than hose (1" hose could use 1½" fitting, 1½" hose could use 2" fitting, etc.)
    • Example : DEF15X18MX2M = DEF flexible connector, 1½" hose diameter, 18" overall length, with one 1½" hex male fixed NPT fitting on one end and one 2" male NPT fitting on the other.
