Frequently Asked Questions

Q. "How do I know the correct Reducing Tee configuration to order?"
A. Reducing Tees are sized by determining the run (straight through portion) of the tee first and then the side outlet. The largest size of the run is always named first, the smaller size of the run second, and then the side outlet size last. Example: 3/4" x 1/2" x 1/2". When only two sizes are provided for the Tee description, the run size is listed first and then the side outlet. This means the run has the same size on both ends. Example: 3/4" x 1/2".  When the run part of a tee is smaller sized than the side outlet part of the Tee it is often called a Bull Head Tee. Example: 1/2" x 3/4" or 3/4" x 1".  This way of determining Tee sizes is the same for all Tees in plumbing no matter the type of material (PVC, copper, ABS, cast-iron, etc.) being used. measurements

Q. "What does Class 150 mean?"
A. All types of pipe and fittings are tested to ensure they meet specific temperature and pressure requirements. Class 150 is one of the ratings given to galvanized and black malleable iron pipe fittings as determined by the ASME (American Society of Mechanical Engineers). ASME B16.3-2006 is the standard used to test malleable iron threaded fittings to make sure they meet the proper pressure and temperature ratings. A Class 150 rating means these fittings have been tested and approved for a maximum pressure of 300 PSI at 150°F. The black and galvanized fittings we sell are also UL (Underwriters Laboratories) and FM (Factory Mutual Insurance Company) approved. FM has an independent testing facility where products are tested to make sure they meet the highest level of standards for safety and property loss prevention.
