Newborn Brothers Caulk Dispenser Pneumatic Variable Ratio Applicator Dual Component

Newborn Model VR400A83 pneumatic cartridge gun. For use with 200ml and 400ml dual component cartridges in mix ratios of 1:1, 2:1, 4:1, and 10:1. 490 lbs of thrust at 100 PSI. Adjustable heavy duty air regulator with air dump valve. Caulking guns, also called caulk or cartridge guns, dispense a controlled flow of products such as caulk, sealants, and adhesives from a tube or cartridge. A manual caulking gun consists of a frame which holds the tube, a trigger, and a rod which moves forward when the trigger is depressed, dispensing the product. Manual caulking guns have a thrust ratio; the higher the thrust ratio, the easier it is to dispense the caulk, sealant, or adhesive. Air-powered or pneumatic caulking guns also have a frame and a trigger, but are used with an air pressure regulator that pushes the product from the tube using air pressure instead of a rod.
