Note: Proper hole preparation is required for effective sealing and performance. Check the pipe seal surface within 5/8˝ of the hole to be certain it is free from conditions that would affect proper gasket sealing. Remove any sharp or rough edges from the hole or upper housing contact area that might affect assembly, proper seating of the locating collar, or flow from the outlet. Check gasket grade to be certain it is suitable for the service. For crosses, ensure double outlet holes are aligned
on opposite sides of the pipe. The use of threaded products other than steel pipe, such as dry pendants, may not be compatible with the female-threaded outlet on the Mechanical Tee. Always confirm compatibility by contacting GRINNELL Mechanical Products.
