MODEL M21 MECHANICAL TEE, FEMALE THREADED OUTLET

The Shurjoint Model M21 features an advanced design and when mounted on hole cut pipe the Model M21 provides a fast and easy mid-pipe threaded branch outlet. Threads are NPT per ANSI B1.20 or BSPT per ISO 7. By utilizing the Model M21 you can eliminate the need for welding or the use of multiple fittings. The M21 Mechanical Tee is com­prised of upper and lower ductile iron housing segments, a grade “E” EPDM rubber gasket (Model M21 & M22 gaskets are interchangeable) and plated track bolts and nuts. 

Mechanical tees are supplied with our standard painted finishes, i.e. orange or RAL3000 red. Optional finishes such as hot dipped zinc galvanized and custom epoxy coatings are also available.

Shurjoint mechanical tees: Model M21, M22, 7721 & 7722 can also be used on applicable IPS size HDPE pipe. When used in conjunction with HDPE pipe the pressure rating would be the lower of the fitting or pipe rating. Please note Shurjoint mechanical tees are not recommended for use on PVC plastic pipe.

Important Note: Model M21 housing segments are not compatible and should not be used with other Shurjoint mechanical tee housing segments such as Model 7721 & 7722 mechanical tees.
