Threaded Crosses — ASME B16.11
A threaded cross is a forged four-way fitting with female threads that joins four small-bore threaded pipes at 90°. Teshi Group manufactures threaded crosses to ASME B16.11 in Class 2000, 3000 and 6000, with NPT threads to ASME B1.20.1.
Also called: screwed cross, NPT cross, forged threaded cross, 4-way threaded fitting
What are Threaded Cross?
A threaded cross has four threaded openings — two on the run and two opposite branches — machined from a solid forging. It allows four threaded lines to meet without welding. Crosses are compact and suit manifolds, sprinkler branches and instrument headers. As with socket weld crosses, the four-way intersection carries higher stress, so they are used mainly in utility and low-hazard services.

FAQ
Threaded Cross: common questions
Where are threaded crosses typically used?
In utility services, fire sprinkler systems, instrument manifolds and test rigs, where four small-bore lines meet in one place and the piping specification allows threaded joints.
Which classes are available?
Threaded crosses are covered in Class 2000, 3000 and 6000 by ASME B16.11, rated for use with Sch 80, Sch 160 and XXS pipe respectively.
Can unused outlets be closed?
Yes. Any unused outlet can be closed with a hex, square or round head threaded plug of matching thread size and material, also to ASME B16.11.
