2K Cartridges
Our u-TAH
®
Universal Cartridge System is a breakthrough in two-component
cartridge design.
The u-TAH Cartridge looks identical to standard caulking cartridges — in fact, you
might not realize it is two-component until you begin to dispense your product. It
is the only cartridge system that maintains accurate ratio control and ts into your
existing 1/10th gallon or 310mL caulking gun. This system also ts into pneumatic
(rod-driven) and battery-powered caulking tools.
The standard u-TAH cartridge contains bleed vents to allow air to escape during lling.
When using low viscosity materials (less than 1000 cps), a “non-vented” version is
available. Contact us for more information.

• The u-TAH cartridge body is molded of a
rigid plastic that won't burst during the most
demanding applications.
• The interior components are fully
assembled, and each cartridge is air tested.
• This 100% factory inspected process
guarantees that, after lling, the cartridge
will maintin a superior shelf life and provide
trouble-free applications in the eld.

• Large valve bores for greater ow
• Molded valve seals ensure long, leak-free shelf life
• Partially used cartridges are easily re-sealed by closing valve
• Pre-inserted pistons for ease of lling through the nose

2K Pistons
The AF
™
Air Free 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
to close 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.
Atlas
™
2K Piston Inserters are a fast, convenient, and cost-
effective way to install AF pistons in 50mL, 200mL, and
300mL Side x Side cartridges.
