Please test the rubber material in DOP liquid for 1.5h at the temperature of 140℃, and MEK liquid for 2h at the temperature of 100, if the rubber material doesn’t change any size and softness, then you can place your order. Otherwise, you’ll be driven crazy by the rubber tube deformation every few months.
