RIBs design are equally spaced and ensure a shallow area remains present around the plunger outer walls - directing unwanted air out of the fluid during both cartridge filling and dispensing. A single wiping edge can allow some material residue to remain on cartridge walls. If you dispense very thick materials, or your current plunger is difficult to insert into the cartridge or traps air when inserted, use this plunger. It provides tight wiper action for most materials, adhesives, liquids, pastes and gels but is an ease to insert into the cartridge, without excessive force. These are perfect for easy installation. Natural in color and made of low density polyethylene (LDPE). For use with all 2.5oz, 6oz, 8oz and 12oz size dispensing cartridges.
