Crossover Sub

Crossover Sub – Available for Lease

Product Overview

Our Crossover Subs are precision-engineered drilling and well intervention tools designed to connect drill string components with different thread types, sizes, and connections. Manufactured from premium-grade alloy steel and engineered to withstand high torque, tension, and downhole pressures, our crossover subs provide a safe, reliable, and efficient connection between incompatible drilling tools, ensuring seamless drilling and completion operations.

Available for lease, our Crossover Subs offer drilling contractors, oilfield service companies, and exploration operators a cost-effective solution for temporary drilling campaigns, workovers, well interventions, and completion projects.

Product Description

A Crossover Sub is a threaded adapter used to join drilling, completion, or production equipment with different connection types or thread specifications. It serves as an essential interface between drill pipes, drill collars, stabilizers, reamers, mud motors, rotary steerable systems, fishing tools, tubing, casing, and other downhole equipment.

Designed for demanding drilling environments, our crossover subs are manufactured from high-strength alloy steel, precision-machined to tight tolerances, and heat-treated for exceptional mechanical strength and wear resistance. Every unit is inspected and tested to ensure superior performance under high-load drilling conditions.

Our crossover subs are available in a wide variety of API and premium thread configurations to suit virtually any drilling or completion application.
