Abstract
A dielectric tube coupling includes a tube-like body having a circumferential ramp on the exterior periphery thereof. Opposed, non-conductive flared sleeves are disposed in surrounding relationship with the body so that the flared portions thereof closely engage opposite faces of the ramp. A threaded connector surrounds one of the sleeves and has an angled internal portion thereof in exteriorly abutting relation with the flared portion of the sleeve. The connector threadedly receives a coupling which includes an internal angled shoulder disposed in exteriorly engaging relation with the flared portion of the other sleeve. The tube-like body has one end sealingly disposed by means of an O-ring and a back-up washer in a seat included in the connector.
