Traditional hose-clamp style connectors don't have a great reputation for performing under pressure.
Because they are fastened on the outside of the pipe, any internal pressure from the system naturally pushes the hose and clamp away from the walls, leading to leakage and potential failure.
In an overpressure situation, hose clamps are normally always the weakest link and give up or let go long before the flexible connector would be due to rupture.
BFM® fitting's patented spigot and snap-fit cuff system means any internal pressure just pushes the cuff of the connector harder against the walls of the spigot, creating an even tighter seal. There is nowhere for product to leak or build-up as there are no crevices on the outside of the pipe for it to escape to.
Our Seeflex 040E connectors have been pressure tested to safely perform under constant pressures of up to 5Psi, and explosion pressures of over 63kPa.
This new high-pressure resistant connector can operate comfortably up to 1.3 bar* of continuous pressure.
The secret to the success of the product is in its make-up: a polyester scrim is internally bonded between layers of Seeflex (an ether based polyurethane).
The polyester scrim restricts the Seeflex and stops it from expanding, providing superior pressure resistance and can be used in all food-contact applications.
Note: Because it is so strong, BFM® cautions against using the new connector in applications where a flexible connector is used to act as a pressure-release point.
*tested on a static 200mm diameter x 200mm long connector - engineering adjustments should be made for changes in
diameter or non-static applications.
