The Newborn 710AL-12 Air Driven Pneumatic Applicator has a lightweight aluminum barrel that fits 1/10-gal. cartridges and has 100 psi of pressure for use with very high viscosity materials. The adjustable air pressure regulator controls the flow of the material, and the air dump valve quickly stops the flow. The quick-change barrel and nipple allow for quickly changing the cartridge or barrel. 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.Newborn Brothers Company, Inc. manufactures sealant and adhesive dispensers and accessories. The company was founded in 1974 and is headquartered in Jessup, MD.
