Read MorePremium Connection for Casing and Tubing
Tubing main seal is a 30o angle taper metal to metal seal, which can provide excellent gas tightness even after repeated make-ups breakouts. The design virtually eliminates all risk of seal galling. Casing main seal is a low taper seal (10% taper on diameter) providing gas tightness under high-tension loads such as with heavy string weights.
