Plastic Cartridges & Air Pistons

PVA offers high-quality polyethylene cartridge inserts and air pistons for packaging compatible fluids. Polyethylene air pistons are designed to fit snugly inside the cartridge tube to wipe the sidewalls clean as it pushes fluid out. Plastic cartridges full of material can be loaded into PVA metal cartridge sleeves with air caps, cartridge drives, or high-pressure cartridge pumps.
