Shenzhen Forbest makes Viton (FKM) Rubber Tubing for tough jobs. Standard rubber fails in hot oil or chemicals. This one doesn’t. Made from virgin FKM. Resists diesel, gasoline, hydraulic oil, acids. Temp range: -20°C to +200°C. Low compression set keeps fittings tight. Low permeability cuts fluid loss. Used in fuel lines, chemical dosing, industrial lube systems.
Viton (FKM) Rubber Tubing from Shenzhen Forbest is made for the jobs that kill ordinary tubing. FKM (fluoroelastomer) started in aerospace. Military aircraft needed seals that would not fail in fuel and hot oil. It works. Today we use the same material for diesel engines, chemical pumps, hydraulic systems, and fuel lines.
It handles petroleum oils, diesel, gasoline, hydraulic fluids, mineral oils, and many acids. Stays flexible at 200°C. Does not turn plastic at -20°C. Resists ozone, UV, and aging for years.
