Air-Powered Sealant Guns

The 950 Series, air-powered sealant guns dispense adhesives or sealants from 2.5, 6 or 12 ounce polyethylene cartridges. Each size of these lightweight, all metal guns, is available in two styles: pistol grip and palm grip.

The guns feature an interchangeable gun body and actuator with a fast change cartridge knob included. The cartridge retainers are corrosion-resistant, will fit all handles and are made of high strength steel to prevent cartridge splitting under pressure.

In operation, the dispense rate is controlled through air pressure, trigger position and nozzle orifice. When the gun is actuated, air pressure forces the plunger down, inside the cartridge, forcing material out the nozzle. When the trigger is released, pressure is removed and dispensing stops.

Manual Sealant Guns

The manually-operated sealant fun for 2.5, 6 and 12 ounce cartridges uses a smooth plunger rod for easy operation. Simply releasing the trigger, releases the pressure; dispensing is easy to control and stops quickly.

Gun Tip/Nozzle Safety

Use extreme caution when cleaning or changing dispense sealant gun tips/nozzles. Always follow the Pressure Relief Procedure first, and then remove the spray tip/nozzle to clean it.

Never wipe off build-up around the tip/nozzle until pressure is relieved.
