BrassCraft's 1/2 in. Mip efv x 1/2 in. Fip x 48 in. Safety+plus gas appliance connector is 1/2 in. Od (3/8 in. Id) with a maximum operating capacity of 60,500 btu's. This safety+plus gas connector combines excess flow technology with the advanced corrosion resistance of procoat, to provide a safer gas connector for home and family. In the event of a gas line rupture or disconnect, the safety+plus valve restricts gas flow at the appliance to a non-hazardous level. This immediate action helps avert the BrassCraft's stainless steel gas connector is protected with a proprietary polymer coating designed to withstand prolonged exposure to harsh household cleaning, plumbing repair and masonry products. Procoat coating is applied to the corrugated stainless steel connector using advanced powder-coat technology. Unlike conventional dipped or sprayed coatings, the procoat coating is baked directly on the connector surface at high temperatures to provide a uniform coating over the entire length of the connector. The coating is applied only after the connector has been 100% leak tested, prior to nut and fitting assembly. This process results in the most complete corrosion resistance available.
