Flexible Connectors

Flexible Connectors

FLEX-ING™ flexible connectors have become the industry standard and benchmark for quality as a means to easily connect a pipework system to other system components such as submersible pumps or shear valves. As an integral part of any system, installers enjoy how easy they make connections in tight spaces while station owners have come to depend on their durability and their simplification of regular maintenance.

FLEXIBILITY IS KEY

The tight working conditions found in dispenser and tank sumps provide little room for installers to work, motivating some manufacturers of flexible connectors to sacrifice overall strength for flexibility. With FLEX-ING™ flexible connectors, there’s no need to compromise. Their corrugated fuel contact layers feature a 25% thicker metal construction and gain flexibility from having more corrugations per foot rather than thinner walls.


Customized to Your Application

FLEX-ING™ flexible connectors offer multiple diameter and length options as well as a wide offering of end fitting connections so you can create the right flexible connector to fit virtually any application.

Quality Construction

Enclosing the corrugated fuel contact layer is a stainless steel braid that is manufactured from only high-grade stainless steel. The precision braiding process used to manufacture the braid gives strength while still maintaining flexibility. 

Ready for Anything

Aavailable in a multitude of end connections to ensure the right fit for any application - including tees, elbows and FRP transitions. Male, female, and swivel end connections with integrated hex-head surfaces provide easy installation and tightening. 

EZ Fit System

The EZ FIT coupling system is specifically designed to make connections in confined spaces simple and tight. The entire flexible connector assembly can be quickly and easily disconnected and pulled out of the inline system without breaking pipe.

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 following example.

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 : FFUL15X18HMX2HM = FIREFLEX flexible connector with fixed end fittings, 1½" hose diameter, 18" overall length, with one 1½" hex male fixed end fitting and one 2" hex male fixed end fitting.
