ASC Engineered Solutions 310062609 – Frequently Asked Questions
1) Will this 1-1/4 street tee thread onto standard 1-1/4 inch black pipe?
Yes. All three openings are 1-1/4 inch and the threads are cut to ASME B1.20.1, which is standard NPT, so it mates with any 1-1/4 NPT black pipe nipple or fitting. Dimensions follow ASME B16.3, so the face-to-center lay length matches other standard malleable iron fittings if you are swapping one in.
2) Is a black malleable iron street tee OK for a domestic water line?
No. Black malleable iron is for gas, fire protection, air, and non-potable service. The black finish is a mill coating, not a corrosion barrier, and it will rust in wet potable service. For potable water in threaded iron, use galvanized fittings, or switch to copper or brass.
3) What is the malleable iron grade on this ASC tee, and does it matter for gas piping?
The casting is made to ASTM A-197, the standard cupola malleable iron spec used for threaded pipe fittings. That is the grade inspectors expect on black iron gas piping, and it is what gives the fitting the ductility to take thread engagement and vibration without cracking the way a grey iron casting can.
4) Do I need a nipple with this street tee?
Not on the male side. The MPT branch threads directly into a female port, so you skip the close nipple you would otherwise need with an all-female tee. The two FPT openings still take male pipe or nipples as usual. Nothing ships with the fitting; pipe dope or PTFE tape is your own.
5) How much does a 1-1/4 inch black malleable street tee weigh?
1.39 lbs each. Useful if you are figuring hanger spacing and support loads on a run with a lot of fittings, or pricing out freight on a bulk order.
