The Figure 730 Mechanical Tee is rated at 3,447 kPa (500 psi) on standard weight pipe . It can be used in place of a tee, a cross connection, or a welded outlet where a threaded or grooved outlet is needed . The Mechanical Tee is ideal for use in retrofit or equipment hookup installations as it can be positioned along the pipe at the proper location in the field, ensuring exact lineup of the branch outlet connection .
All Figure 730 Mechanical Tees are provided with a ductile iron lower housing section for increased strength and dependability . This design provides stability and rigidity while inhibiting damage to the pipe during tightening .
