COMPATIBILITY FIRST
DLC™ is designed for customers who value compatibility first, with practical performance and more flexibility in how drill pipe is sourced, converted, inspected, and repaired.

COMPATIBILITY COMES FIRST
Most customers will agree the industry doesn’t need more proprietary connections, and that is why the DLC™ connection is compatible with Delta™ – the industry renown 4th generation rotary shouldered connection.
Compatibility creates a path forward. It supports existing infrastructure instead of replacing it, works within real operating environments, and helps customers evaluate new options without the fear of starting over from scratch.
The first value of DLC™ is simple: compatibility you can use.
WHY DLC™
DLC™ starts with compatibility; make a change and keep existing infrastructure stable. It also reflects the practical advantages customers care about when selecting and managing drill pipe: field performance, day-to-day usability, and a more workable approach to supply and manufacturing.
INDEPENDENTLY FLEXIBLE
As an independent technology DLC™ is uniquely positioned to allow options that other connections do not depending on what best fits the customer, the operation, the asset condition, and the reality of today’s modern commercial landscape.
DLC™ is a strong fit for customers who value compatibility first, but also want more flexibility in how drill pipe is sourced and managed.
