Brass Craft"s 3/4 In. FIP x 3/4 In. MIP x 60 In. Recoat Gas Appliance Connector is 5/8 In. OD (1/2 In. ID) tube with a maximum operating capacity of 93,200 BTU"s. This Recoat stainless steel gas connector is engineered with added safety in mind. The proprietary polymer coating is designed to withstand prolonged exposure to harsh household chemicals, UV rays and salt. Recoat is applied to the corrugated stainless steel connector using advanced powder-coat technology. Unlike conventional dipped or sprayed coatings, the Recoat coating is baked directly onto 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.
