Description
AD903-RP is a soft black rubber piston that is used to prevent tunnelling in high viscosity fluids - care should be taken to ensure the piston is suitable for the dispensing application. Compatible for use with most liquids and pastes but aggressive solvents might cause the rubber to expand. For solvent use, consider the polyethylene wiper piston. This wiper piston is used with 3cc sized barrels only.
Pistons ensure that the pressure is evenly spread across the fluid surface to provide consistent dispensing. Wiper seal pistons prevent dripping and eliminate material waste by wiping the syringe barrel wall clean as fluid is dispensed. Maximum operating pressure is 100psi (6.9 Bar).
Rubber pistons are a tighter fit for use with medium to high viscosity materials or with mechanical devices such as our manual syringe gun to help slow down leakage past the double wiping edges. Can be used with pneumatic dispensing machine applications. Sold as a pack (50/pk).
