These 200 through 600 ml adhesive cartridges offer an economical choice. The robust uni-body design has a rugged connection between the cylinders and offers a generous lead-in for ease of piston insertion. This family of one-piece, closed-end outlet cartridges incorporate a patented “snap-off” closure—molded in one operation in either PP or nylon. This eliminates many of the assembly steps required in open-end cartridges, offering a quality, cost-effective system to the adhesive manufacturer.
