AF Pistons The AF piston does a superior job of venting all of the air between the material and the piston. Its unique design does not require a shim to bleed the air, nor does it require a second step to insert a center bleed plug. This piston bleeds air around the circumference of the black plug and uses the force of hitting the material toclose itself in a single step. The AF piston provides a more visible indication when the piston is completely closed, i.e. the black center plug is ush with the top of the piston. Further, since the material of construction of the AF piston is a PE/PBT combo, it is compatible with most materials, simplifying inventory. In conjunction with your evaluation of the new 50mL cartridge, please contact your salesperson free samples of the new AF Piston.
