Evergreen Quick Seals

Installing fire suppression systems in hoods and ducts means all joints and seals must be liquid-tight per the National Fire Protection Association (NFPA) 96 specifications. To side-step the hassle of in-field welding, simply use penetration seals and install these seals within a few minutes with a standard wrench.

National Fire Supply is certified by the National Association of Fire Equipment Distributors (NAFED). We offer an extensive selection of Quick Seal fire equipment parts from the award-winning Evergreen Tool Company that meets industry standards.

Our Quick Seal Selection

We proudly stock Evergreen Quick Seals. A chrome-plated Evergreen Quick Seal is the go-to penetration seal in the industry. While it offers a liquid-tight seal, it also fortifies system piping and is corrosion-resistant. Since it is designed to stop the leakage of liquids and grease, a liquid-tight Quick Seal adapter accepts conduit and cut pipes with threaded ends.

We also stock compression seals that offer a liquid-tight seal around the outside of pipe, tubing and EMT conduit. These adapters provide the same strength as a welded joint without needing in-field welding. These products make excellent fast hood seal adaptors, ensuring no grease leakage.
