Black-series130 equal tee named separately in the supplier’s range.
The catalogue separately names a black No.130 equal tee. Provide the run and branch connections together with the required pipe layout when requesting the fitting. Confirm the selected connection size, thread specification and finish with Changtaifeng; the equal-tee label establishes the published form rather than a verified pressure class or material grade.
