This is a new line of 99A shore hardness PTFE high temperature fuel tubing designed according to the best industrial practices for heat protection.
PTFE is one of the most chemically resistant plastics. It will withstand kerosene/ diesel/ alcohol flow for life, without alteration of its characteristics.
Additionally, this product is much more resistant than any other tubing to high temperatures and flames, making the 4 mm OD tube ideal for connection to the engine in a bypass duct with a greatly increased level of safety.
The 6 mm tubing is designed for the upstream side of the pump, or to connect engines with on-board pumps ( like some Jetcat units ).
Notice: This is a hard wall product is specifically formulated to bend without kinks ( contrary to regular PTFE tubing ) but does require more pressure from safety wires ( typically thicker gauge wire required ). For this reason, we recommend the use of our MIL spec Pisco push-to-connect fittings which work amazingly smooth and secure with these tube.
