Pistons are used with syringe barrels to ensure that the pressure is evenly spread across the fluid surface to provide consistent dispensing. Flat walled pistons prevent dripping and eliminate material waste by pushing out adhesives, gels and pastes under pressure from the syringe barrel. Maximum operating pressure is 100psi (6.9bar).
Straight Wall Pistons (red) are recommended for reduced stringing and "bouncing" with high viscosity products. The flat edges without wiper blades do not restrict the piston movement. Supplied in sealed packs of 1000.

Use this piston with the 3cc 700 series barrel 7030LL1NPK. It is ideal for general use with stringy and viscous pastes.
Pistons are made of plastic to wipe the adhesive, paste or liquid from inside the syringe barrel as they move down. Once a syringe has liquid inside, insert the piston and push down on one side. This will allow air to escape and ensures the piston sits directly on the fluid without an air gap. When bottom filling using a barrel filler, the piston is pushed down and moves up as the liquid is fed into the syringe barrel.
Syringe barrels are designed for use with pneumatic dispensing equipment or syringe guns. They are thick walled with wide flanges and so designed for high pressures. The internal bore is zero draft meaning there is no taper. This ensures the wiper piston inside moves down without restriction to improve dispense performance. Use these barrels with pastes, adhesives, solvents, epoxies, RTVs, silicones, PVAs, inks and gels. This range have luer lock ends for twist on tip attachment.
Barrels are shipped with every new dispenser and syringe gun that we supply. Barrels are moulded in high density polypro and have much thicker walls than a medical grade syringe. The internal bore has no taper and this ensures the wiper piston moves consistently down the barrel without restriction. The wide flanges at the top are for quick attachment to the air adapter assembly (to a dispenser) or to a manual syringe gun. This design ensures syringe barrels do not come loose or break under air pressures up to 100 psi. The luer lock tip attachment provides secure dispensing under high pressure.
Pistons have blades to wipe the adhesive, paste or liquid from inside the syringe barrel as they move down. The blades also act to stop liquids from going past them as they dispense. Once a syringe has liquid inside, insert the piston and push down on one side. This will allow air to escape and ensures the piston sits directly on the fluid without an air gap. When bottom filling using a barrel filler, the piston is pushed down and moves up as the liquid is fed into the syringe barrel. Pistons can provide a barrier seal for liquids placed inside. But for more protection when dispensing watery liquids and cyanoacrylate adhesives, use our filter trap in the airline adapter assembly to your syringe dispenser.
