ASC Engineered Solutions 311030407 – Frequently Asked Questions
1) Can I use this galvanized malleable iron tee on a fire sprinkler line?
It carries UL/FM approval, so it is acceptable for fire protection piping where a listed threaded fitting is required. It is standard (STD) pattern malleable iron with pressure ratings per ASME B16.3. Confirm your AHJ accepts threaded malleable iron at the working pressure of that system.
2) Is this tee galvanized inside and out, and can it go on a domestic water line?
The finish is hot dip galvanized to ASTM A-153, which coats the casting inside and out including the threads, so it is suited to wet service and outdoor or damp locations where black iron would rust. Malleable iron to ASTM A-197 is commonly used on water, air, and gas service lines. Note galvanized fittings are generally not used on natural gas piping in many jurisdictions, and it is not a lead free certified potable fitting on the strength of these specs alone.
3) What is the difference between a STD malleable iron tee and an XH tee?
STD marks this as standard pattern, the Class 150 weight used for ordinary threaded pipe work. Extra heavy (XH, Class 300) fittings have thicker walls and longer threads for higher pressure, and their dimensions differ, so they are not a like for like swap in a run laid out with standard fittings. For general plumbing, compressed air, and listed sprinkler branch work, the standard pattern is the usual choice.
4) How much does the ASC 1-1/4 inch galvanized malleable iron tee weigh?
1.35 lbs each. Worth knowing when you are pricing out a hanger layout or figuring the loaded weight of a long threaded run, since malleable iron fittings add up quickly over a horizontal main.
5) Does this tee come with anything, or do I need to order nipples and sealant separately?
You get the tee only, model 311030407. Nipples, couplings, unions, and thread sealant or PTFE tape are separate. On galvanized threaded work most installers use a pipe joint compound rated for the service rather than tape alone, particularly on sprinkler or air lines.
