Product Overview

Manufacture high-integrity casing connections with our API Extreme Line (EL) laydown threading inserts. Unlike standard API Round or Buttress threads, the Extreme Line connection features a unique integral joint design with a metal-to-metal seal, requiring high-precision inserts to maintain seal integrity under extreme downhole pressures.

These carbide threading inserts are engineered to cut the specific 6 TPI and 5 TPI profiles with the correct taper, ensuring the box and pin members mate perfectly. The substantial 1/2″ I.C. size provides the rigidity needed for these heavy cuts, a task beyond the capacity of a standard 16er threading insert.

Key Features & Benefits

• API Compliance: Precision ground to produce the accurate thread form and taper required for Extreme Line certification.
• Optimized Grade: High-toughness carbide withstands the interrupted cuts and abrasive nature of casing steel.
• Matched Sets: Available in paired External and Internal models to ensure connection compatibility.

• Directional Options: We provide standard right-hand solutions and can supply left hand thread insert models for specialized string configurations.
