P C Cox Easiflow Gun (79714)

Hello, this tool can dispense single component cartridges up to 400ml in volume. Most sealants are sold in 310ml cartridges. A few UK brands are sold in up to 400ml single component cartridges. Please note that the Easiflow mechanism is intended for use with low viscosity sealants and adhesives. It will give a long bead per trigger pull and is highly durable when used for its intended purpose. If the material is thicker or becomes much more viscous when it gets cold, then you should consider our mid-power or high power tools. If the cartridge contains two components that are mixed by a static mixing nozzle but can be dispensed with a single plunger, then you must also use one of our more powerful tools.

Hello, yes, the UK specification Easiflow HD frame can take single component cartridges up to 400ml in volume. It is well-suited to thinner materials with a low viscosity such as silicone or acrylic sealants. Using those, this tool will give a long bead for each trigger pull.

Hello, The black plastic part belongs on the dispenser. Please do not remove it. It actually helps control the flow of material when you stop squeezing the trigger. It sounds like there may be a problem with your tool. If it is operating correctly, you should be able to pull the rod back by pressing the release plate at the back of the dispenser with your thumb. Sorry if this is teaching you to suck eggs, but the method is as follows: Hold only the handle/butt of the dispenser - do not press the trigger when trying to retract the rod. Press the release plate under the hooked rod with your thumb. This allows the rod to move backwards. Pull the rod back by its hook end using your other hand.

This sealant gun and the more powerful 400ml tool are both designed to take cartridges which can be up to 400ml in volume and roughly 250mm in length. Please be careful not to confuse a 380ml two component cartridge, such as chemical anchor cartridges, with the standard 380ml single component cartridges. Hope that helps!

Hello, yes it is designed specifically for the UK market where the longer cartridges up to 400ml in volume are popular. You have a choice of this model, for use with thinner materials like silicones or you can get our more powerful blue gun. The blue one is listed as the PC Cox Sealant and Adhesive Dispensing Gun. It is designed for use with thicker adhesives, working at lower temperatures or simply for professionals who have to apply a lot of material and want a more comfortable tool. Both can take cartridges up to 400ml.
