BrassCrafts ProCoat 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. ProCoat 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 onto the connector surface at high temperatures to provide a uniform coating over the entire length of the connector. This process results in the most complete corrosion resistance available.
