The INTERTOOL® Super Light Spray Foam Gun is composed of aluminum with a PTFE ("Teflon") body, basket, needle and tip. The Patented advanced flow control knob makes it easy to manage the amount of foam applied which means you can avoid wasting material. The durable polypropylene handle prevents foam from sticking and the non-slip trigger make for precise foam release. Includes 4 extra tip attachments for hard-to-reach areas.
