EFD’s Optimum® clear cartridges are engineered with precision; made from a clear polymer that's suitable for all assembly fluids except light-sensisitve materials.

They feature a Zero Draft™ design to improve fluid flow characteristics and reduces turbulence by ensuring the internal diameter is consistent from top to bottom with no taper restricting piston travel or affecting process results.
