Product Introduction
Mismatched flanges, hubs and pressure ratings are the most common fit problem in any wellhead stack. Our API 6A adapter spools, crossovers and wellhead tees close those gaps — bridging end connections of different sizes, pressure ratings and types in a single pressure-rated component while maintaining full wellbore integrity.
Adapter Spools & Adapter Flanges — The universal connector of the wellhead. Bridge two different end connections (flange × flange, flange × hub, or hub × hub) across different bore sizes and pressure ratings, including spacer and blind configurations.
Crossover Spools— Transition between casing or tubing programs within the wellhead stack, changing bore size, pressure rating or connection type in a single compact, pressure-rated component.
Wellhead Tees— Provide a lateral outlet for production, testing or injection operations. Available with studded or flanged outlets, in vertical or horizontal run configurations to match your wellhead layout.
