tiger cross-section


JFETIGER™ has been designed and tested to meet the needs for critical well loads. The design incorporates metal-to-metal seals with a 17° internal torque shoulder to ensure sealing under extreme loads. The negative load flank thread form and coupled design provide 100% tension efficiency for the standard coupling.

Special clearance coupling OD’s are available with full pipe body internal and external pressure ratings.

Reduced gap between stabbing flanks on the pipe and coupling thread. Increased resistance to damage from compressive loads.
Negative load flank angle on threads. Increased tensile and bending capacity while maintaining gas tight seal.
25 degree angle for thread stabbing flank. Quick make up and increased resistance to cross threading.
Different corner radius for load flanks for pipe and coupling threads. Increased resistance to galling.
