Pistons when used with syringe barrels 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).
Wiper pistons are a tighter fit for use with low to medium viscosity fluids or with mechanical devices such as our manual syringe gun to help slow down leakage past the double wiping edges. Supplied in sealed packs of 1000. This version has extended wiper blades.

Pistons are made of polyethylene and have dual 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.
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 plastics 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.
