Frequently Asked Questions on Tee Fittings
Key engineering, tolerance, and international compliance answers from our metallurgical quality desk.
An equal tee has all three outlets of the same size, used when the branch line is the same diameter as the main line. A reducing tee has a smaller branch outlet, used when the branch line requires a smaller diameter than the main run pipe.
