Investment Casting Tee
What is an Investment Casting Threaded Tee?

A Threaded Tee is a T-shaped fitting with internal threads on all three ends, used to split or combine fluid flow in a pipeline at a 90° intersection. Precision-cast using the investment casting method, threaded tees offer dimensional uniformity, excellent surface finish, and tight sealing in non-welded piping systems.
These fittings are especially useful in chemical plants, fluid skids, food processing lines, and marine applications, where hygiene, corrosion resistance, and easy installation are essential.
Key Features
- Three-Way Connection – Divides or joins flow in a piping system.
- Female Threads on All Ports – Enables easy screw-on assembly.
- Equal and Reducing Configurations – Fits uniform or varied pipe sizes.
- Mirror Finish Available – For sanitary and food-grade systems.
- Engineered for Leak-Proof Operation – Conforms to ASME and ISO standards.
