X/Overs (winged)
About the product
Crossovers, also known as X/Overs, transitions or adapters, are transition pieces that connect two components with different thread types, diameters or pressure classes. They form a reliable connection within your string without compromising safety or compatibility.
Deep Drill supplies crossovers for casing, tubing, pup joints and other OCTG components. Our products can be used in geothermal energy, oil and gas extraction, salt caverns and CO₂ projects, where safe sealing and material quality are essential.
