The Eastman 5/8-IN OD gas range connector kit is designed to connect most major brands of gas ranges to a shut-off valve. The connector is certified for use with most ranges with gas ratings up to 106,000 BTUs. The gas range connector kit includes an ArmorBoost EFV (thermal excess flow valve). The ArmorBoost EFV from Eastman is designed to help protect you and your family from catastrophic ruptures or disconnects in your gas line. The ArmorBoost valve immediately restricts gas flow to help protect you from the build-up of flammable gas. The valve will remain activated until the gas line is properly repaired. For added protection, the ArmorBoost EFV features a special fire-safe thermal ring that expands to stop gas flow when extreme temperatures of 350Degree plus are reached. The DuraCoat Epoxy Coating provides extra protection from corrosion, chemical stains from common household products, and UV rays and is approved for indoor/outdoor use. This kit includes (1) 48-IN 5/8-IN OD epoxy-coated gas range connector, (1) 3/4-IN MIP (TAPPED 1/2-IN FIP) ArmorBoost EFV auto shut-off valve, (1) 3/4-IN MIP (Tapped 1/2-IN FIP) fitting, (1) 1/2-IN MIP (Tapped 3/8-IN FIP) fitting, (1) leak detector solution, (1) thread sealant.
