162 PP Pipe & Fittings have an excellent durability against acid, alkali and some organic solvents. In addition, they exert favorable chemical-resistance in a high temperature range. In addition to the chemical-resistance shown below, things such as temperature, concentration, pressure, etc. of solvent need to be considered at the time of making a selection. If you have any concerns, it is recommenced to conduct a proof test. Please contact us for chemicals, etc. not listed in the table.
