ASC Engineered Solutions 310526603 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 310526603 black malleable iron tee take on each opening?
It's a reducing tee: 2-1/2 inch on the run (both ends) and 1-1/2 inch on the branch outlet. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples cut to NPT per ASME B1.20.1.
2) Is this XH tee the same as a standard Class 150 black malleable fitting?
No. XH means extra heavy, Class 300 style malleable iron, with thicker walls and a higher pressure rating than a standard black malleable tee. Dimensions and pressure rating both follow ASME B16.3. If your drawing or existing line is standard weight, the XH fitting is heavier and will not match the standard-weight face-to-center dimensions.
3) Is black malleable iron pipe fitting OK for water lines, or only gas and sprinkler?
Black finish malleable iron, made to ASTM A197, is for black steel pipe systems: natural gas, fuel oil, compressed air, fire protection, and closed-loop hydronic heating. It has no corrosion-resistant coating, so it's not used for open potable water. For potable or wet exposed service, use a galvanized malleable fitting instead.
4) Will this tee thread onto standard NPT black steel pipe I already have?
Yes. The threads are cut to ASME B1.20.1, the NPT standard used on all standard black steel pipe nipples and field-cut threads, and the laying dimensions follow ASME B16.3. Use pipe joint compound or PTFE tape rated for the service on the male threads.
5) Do I need a bushing to get down to the 1-1/2 inch branch on a 2-1/2 inch main?
No. This is a reducing tee with the reduction built into the branch outlet: 2-1/2 inch FPT on both run ends and 1-1/2 inch FPT on the outlet. Using the reducing tee instead of a full-size tee plus a bushing gives you one less joint to seal and keeps the assembly shorter.
