Description
The Cox PowerFlow cartridge gun is a 310 mL cradle-style manual dispenser built for single-component sealants, adhesives, and caulks that ship in the standard 10.5 oz cartridge. The 12:1 mechanical advantage gives steady bead control with a moderate hand load, and the rotating frame lets the cartridge turn freely so the seam line stays on target as you walk a long joint.
What is in the Cox PowerFlow cartridge gun
Built-in features include a seal puncturing tool, a pressure relief device that drops cartridge pressure when the trigger is released, an integral ladder hook, and a rotating frame for one-handed bead orientation. Maximum force at the cartridge face is around 562 lbf. Cradle length is 233 mm and the gun weighs roughly 0.75 kg.
When to spec the Cox PowerFlow cartridge gun
The 12:1 ratio is the right balance for most polyurethane, silicone, and MS polymer caulks in 310 mL cartridges. For thicker structural sealants or chilled material, step up to the PowerFlow HP at higher mechanical advantage. For thin-flow cartridges and finish work, the standard PowerFlow handles the load with less hand fatigue and tighter bead control.
Maintenance for the Cox PowerFlow cartridge gun
Wipe the drive rod after each shift and clear cured material from the cradle and nose ring. The pressure relief release helps prevent after-flow when you set the gun down. Check the rotating frame for grit if it starts to bind. A drop of dispenser-safe lubricant on the drive rod keeps the action smooth across long jobs. Replace cradle springs or trigger return springs every couple of years on guns that see daily production use, since worn springs are the most common cause of soft trigger feel.
