The Elkhart Flair-It 16817 is a 90-degree plumbing elbow adapter designed for fresh-water systems in RVs and trailers. It connects 3/8-inch PEX tubing to a 1/2-inch female BSP swivel connection. Its white plastic construction and angled design help simplify plumbing connections in confined spaces. Confirm thread type and tubing compatibility before installation.
