A dielectric tube coupling includes a tube-like body (10) having a circumferential ramp (16) on the exterior periphery thereof. Opposed, non-conductive flared sleeves (30,40) are disposed in surrounding relationship with the body (10) so that the flared portions (34,44) thereof closely engage opposite faces (18,20) of the ramp (16). A threaded connector (70) surrounds one of the sleeves (40) and has an angled internal portion (74) thereof in exteriorly abutting relation with the flared portion (44) of the sleeve (40). The connector (70) threadedly receives a coupling (50) which includes an internal angled shoulder (54) disposed in exteriorly engaging relation with the flared portion (34) of the other sleeve (30). The tube-like body (10) has one end (14) sealingly disposed by means of an O-ring (64) and a back-up washer (68) in a seat (78) included in the connector (70) |
