Professional foam guns and cans give you precise application and higher yields than one time use straw cans. Our dispenser gun features a PTFE coated basket, dispensing needle and ball valve to promote easy cleaning and unrestricted flow of foam. The control knob  allows adjustment of bead size and gives you precise application of foam sealants and adhesives. Needle valve control eliminates waste by allowing you to cut off foam flow completely; this allows you to restart and use the same can for up to several weeks. Built to last, the quality components and construction will keep on working when other guns fail.
