Shenzhen Forbest makes the Oil Resist Viton Tube for hot oil and chemical service. Standard rubber tubes swell and crack. This one doesn’t. Made from virgin FKM (Viton® equivalent), it handles diesel, gasoline, hydraulic oil, and acids. Temp range: -20°C to +200°C. Flexible, tough, and low permeability. Used in fuel lines, lube systems, and chemical dosing.
Oil Resist Viton Tube – No Swell, No Crack, No Leak
1. Product Introduction
This tube is made from FKM (fluoroelastomer), the same material used in aerospace fuel seals and F1 racing fuel systems. It does not react with petroleum oils, diesel, gasoline, hydraulic fluids, or most chemicals. It stays flexible at 200°C and does not turn into plastic at -20°C.
What makes it different:
-
Zero swelling in diesel or biodiesel
-
No hardening after 1000 hours at 150°C in engine oil
-
Compression set below 20% – fittings stay tight
-
Ozone and UV resistant – fine for outdoor use
-
Low fuel permeation – less smell, less loss
