The Refined Fuel Corrosion Test Cylinder from L-K Industries is designed especially for conducting ASTM and NGPA silver strip corrosion tests of petroleum engine fuel. Each unit is precision machined from stainless-steel for noncorrosive product applications. It is compatible with the L-K Industries Refined Fuel Corrosion Test Cylinder Heater and in compliance with industry standard ASTM 7671. It features all stainless-steel construction for durability and extended lifetime. No wrenches or other tools are required, so the unit can be used anywhere onsite. The placement of the O-ring, a common replacement part, allows for easy access and reduces down time.
