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 350-degree + 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.
