It is more flexible in tight spaces without collapsing. The color and texture remind me of RTV gasket making silicone in automotive applications, but these (very old) tubes do not have any hint of the pungent oder of RTV gasket maker, or anything else for that matter.

I'm looking for a hose that is more flexible than typical rubber (like automotive) and PVC (gardening/aquariums) hose in a 1/4in or 6mm ID for ethylene glycol at pressures between 1 & 2 bar and at 30-100 C. I need to turn around a 50mm radius reliably with flexibility and without substantial (~15%+) constriction... If any experts are around – TIA

I recommend pressure switch tubing for furnaces. Not sure if it'll take that bend radius though.
