06343 (Elkhart Supply – Flair-It) is a straight transition fitting designed for compatible plumbing tubing in recreational vehicles and other water systems. Made from durable white plastic, it provides a secure connection for 5/8" outside-diameter tubing. The Flair-It fitting system uses a nut and flared insert to grip the tubing and create a reliable seal without specialized installation tools. Confirm tubing material, outside diameter and system compatibility before installation.
