The Elkhart 28810 EcoPoly 90-degree elbow adapter connects 1/2-inch PEX tubing to a 3/8-inch male NPT threaded connection. Its black plastic construction and angled design make it useful for compatible fresh-water plumbing installations in recreational vehicles and trailers, particularly where space is limited. This fitting is designed to redirect the plumbing line by 90 degrees. Confirm tubing compatibility, thread specifications and system requirements before installation.
