Foam N' Seal FNS500 Polyurethane Foam Sealant Dispenser

The Foam N' Seal FNS500 is our top of the line foam sealant and adhesive dispensing gun. It offers better value and is comparable or superior in design when compared to competitor foam dispensers such as the GREAT STUFF Pro 14 and 15 insulating foam guns. Because it is engineered with quality raw materials, the FNS500 is very dependable and dispenses consistent foam selant every time. It also provides precision control over foam dispensing to fill gaps, cracks, voids and holes. It is also ideal for filling voids in window and door jambs. The stainless steel foam canister adaptor basket, check-valve and foam control gun needle are all coated with Teflon for greater non-stick and reliable performance and longer life. The exterior gun barrel is also coated with Teflon for easier clean-up of uncured and cured foam. The FNS500 foam gun is reusable up to 30 days.
