The Series 824 from Guill Tool is a co-extrusion crosshead designed for irrigation tubing with an emitter tool.

The Series 824 from Guill Tool is a co-extrusion crosshead designed for irrigation tubing with an emitter tool. Manufactured from stainless steel, this crosshead features balanced flow design with spiral technology that improves flow characteristics at all extruder speeds. Dual-feed ports provide concentric compound flow, while the splits flow from one extruder to feed the inside and outside layers via a manifold assembly. The crosshead is adaptable to virtually all popular extruders on the market, the company says.  

Capacities include a maximum die inner diameter of 1.875", maximum core outer diameter of 1.25", maximum tip OD of 1.50" and maximum emitter tool OD of 1.18". The design allows the emitter insertion tool to pass completely through the crosshead ID.  Gum space adjustment is performed with die nut rotation, while a two-stage clamping mechanism allows easier concentricity adjustment. Quick-change tooling and a tool kit for disassembly and re-assembly are provided with the unit.
