Cartridge Plungers

Offering the widest range of industrial dispensing cartridges and plungers for use with adhesives, gels, epoxies, silicones and lubricants. All plungers are industrial grade safe and are certified silicone-free. Plungers ensure liquids and pastes are dispensed from the cartridge without waste or mess.

Cartridge plungers ensure that the pressure is evenly spread across the fluid surface to provide consistent dispensing. Wiping edges prevent dripping and eliminate material waste by wiping the cartridge walls clean, as fluid is dispensed. The plunger is inserted into the cartridge once filled (or pre-inserted when bottom filling) and it moves down the inner walls under pressure to ensure all liquid material is dispensed without waste. Plungers can be used at pressures up to 100psi , for example when used with a pneumatic cartridge gun system.

Dispensing without a plunger inserted can result in unreliable dispensing deposits, as the supplied air pressure can become trapped inside the fluid, resulting in void pockets. In addition, moisture found in the air, can affect the properties of the fluid.

All plungers are industry compliant silicone and chloride free, low friction polyethylene. Supplied in sealed and labelled packs.
