Crossover Subs

At W74 Oil Tools, we are proud to offer a selection of crossover subs for your oil or gas business. Crossover subs are required for oil rig drill strings and help in connecting one crossover size to the other. They are used as the disposable components for extending the connection of an expensive drill stem member.

Crossover subs feature a side port or an inline port for proper circulation of the oil or gas. We will have the connections cut according to the certifications and ground gauges. The crossover subs are machined from heat-treated alloy to ensure durability and strength.
