Check the condition of the dispenser. Look for excessive play in the piston rods or loose piston rod ends. Check cartridge position in the dispenser and ensure that it sits parallel to the piston rods. For pneumatic systems, ensure there is a regulator on the dispenser providing controlled pressure. Adjust pressure to provide adequate flow without overpowering the system. If leaking occurs, your supplier may wish to inspect the molded part for defects or damage as part of their quality control program.
