A Custom T type union tee must match the manifold’s pressure, connection size, service environment, and alignment needs. Our API High-Pressure T-Type Union Tee uses forged alloy steel, supports pressure up to 103 MPa, and provides ±15° angle compensation. Use these checks to decide whether its 2-inch 1502 or 4-inch 1003 configuration fits your drilling, fracturing, or cementing system.

Maintenance access and suitability for drilling, fracturing, or cementing manifolds
A Custom T type union tee should be selected from the conditions around the connection, not from the branch shape alone. Pressure, service environment, connection size, and the amount of alignment movement all affect whether the fitting suits your manifold.
Our API High-Pressure T-Type Union Tee is made from high-strength forged alloy steel and is intended for drilling, fracturing, and cementing systems. It supports pressure up to 103 MPa, uses a T-type union connection, and provides ±15° angle compensation. Those figures give you a practical starting point for checking a high-pressure oilfield layout.
Start with pressure and service conditions
Choose this Custom T type when the working system requires a high-pressure union tee and the specified pressure is within 103 MPa. The fitting is positioned for ordinary, low-temperature, and H2S service, so it can suit projects where the manifold may encounter demanding temperature or hydrogen sulfide conditions.
Pressure should be checked for the complete assembly, including the connected pipe, valves, unions, and other fittings. The tee’s pressure rating does not replace the rating check for the surrounding system. Send the operating pressure and service environment with your inquiry so we can confirm the intended configuration.
The forged alloy steel body is suited to oilfield manifolds exposed to pressure fluctuations. For a fracturing manifold, picture the tee installed at a branch point where fluid routing must remain secure during high-pressure work. Confirm the system pressure, fluid conditions, and connection layout before ordering.
Match the connection size and layout
The listed typical configurations include 2-inch 1502 and 4-inch 1003. Use the configuration that matches the mating components in your manifold. The connection type is a T-type union, which suits layouts that need a branch connection and union-style assembly.
Measure the mating connection size and identify the pressure series used by the existing manifold. A correct nominal size alone does not establish compatibility if the connected components use different connection details. Include a drawing or clear connection schedule when asking us to prepare a quotation.
The tee also supports ±15° angle compensation. This helps when connected lines require limited alignment adjustment within that range. It does not mean the fitting can replace proper pipe support or correct a major layout error. Check the actual offset, branch direction, and available movement in the installed manifold.
Consider maintenance access
The hammer-driven design allows tool-free assembly and disassembly with a hammer-driven method. This suits oilfield teams that need to access union connections during manifold maintenance without relying on a conventional wrench at the connection.
Picture a cementing line that requires a tee connection to be opened during a maintenance window. The assembly method can make the connection easier to access in a crowded manifold, provided the working area allows safe hammer use and the fitting is installed as part of a suitable system. Plan clearance around the union and identify the maintenance approach before finalizing the layout.
Our product range for this application is the API High-Pressure T-Type Union Tee. It is the applicable choice here when your system needs a forged alloy steel T-type union tee for drilling, fracturing, or cementing service and the pressure, size, temperature, H2S, and alignment conditions fit the listed range.
Questions to settle before ordering
Is the tee suitable for H2S service?
Yes, the tee is intended for H2S-containing service as well as ordinary and low-temperature environments. Tell us whether hydrogen sulfide is present, together with the operating pressure and connection configuration. That information lets us check the requested service condition against the tee’s intended use before we prepare the order details.
What size options should be checked first?
Start with the 2-inch 1502 and 4-inch 1003 configurations listed for this tee. Compare the full connection details with the existing manifold, including the branch and run connections. Send the mating component schedule or a dimensional drawing if the layout uses a different size or connection arrangement.
How much alignment movement can the tee accommodate?
The tee provides ±15° angle compensation. Treat that as the available deflection range for connection alignment, not as permission to force the piping into position. Measure the actual offset and confirm the branch direction, support arrangement, and clearance around the union before selecting the tee for a new or modified manifold.
Send the manifold details
Our API High-Pressure T-Type Union Tee fits high-pressure drilling, fracturing, and cementing manifolds that need a forged alloy steel T-type union connection, with pressure up to 103 MPa and limited angle compensation. Send the required size, pressure, service environment, branch layout, quantity, and a drawing or connection schedule for a quotation.
