This 3/4 in. ID, 48 in. long moveable grade gas connector is composed of a 304 stainless steel corrugated tube covered with a tight weave stainless steel braid. The outside hose coating is an antimicrobial PVC coating that inhibits growth of bacteria, mold and mildew on the connector. Rotational technology fittings on both ends of the connector rotate 360??, greatly reducing stress at both connector ends.
