ASC Engineered Solutions 311050207 – Frequently Asked Questions
1) What are the three outlet sizes on the ASC Engineered Solutions galvanized malleable iron reducing tee, model 311050207?
It is a 2 x 1-1/2 x 1-1/4 inch reducing tee: the run is 2 inch, the second run opening is 1-1/2 inch, and the branch is 1-1/4 inch. All three openings are female pipe thread (FPT), so it takes male-threaded pipe nipples or threaded pipe ends at each connection.
2) Will this 2 x 1-1/2 x 1-1/4 malleable iron tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the NPT standard, so it mates with any standard NPT male pipe or nipple in the matching sizes. Use pipe dope or PTFE tape on the male threads as usual for a tapered thread joint.
3) Is this galvanized tee approved for fire sprinkler piping?
It carries UL/FM approval, so it is acceptable for fire protection piping where a UL Listed, FM Approved threaded fitting is called for. It is a standard (STD) pressure class fitting rated per ASME B16.3.
4) Galvanized or black malleable iron tee, which one do I need?
Galvanized is the corrosion-resistant choice, and this one is hot dip galvanized to ASTM A-153. That makes it the normal pick for wet sprinkler systems, water service, and damp or outdoor locations. Black malleable iron is the usual choice for gas piping and dry interior service. Both are the same malleable iron body and the same NPT threads, so the only real decision is the environment the pipe runs through.
5) Can I use a 2 x 1-1/2 x 1-1/4 reducing tee instead of a full-size tee with bushings?
You can, and it is the cleaner install. A single reducing tee gives you the 2 inch run, a 1-1/2 inch opening, and a 1-1/4 inch branch in one casting, so you avoid stacking two bushings and the extra leak paths and pressure drop that come with them. Note that many sprinkler and code-inspected installations restrict bushings, and this fitting is UL/FM approved as supplied.
6) Does this ASC tee meet spec for a job drawing calling out ASME B16.3 malleable iron fittings?
It does. The body is malleable iron to ASTM A-197, dimensions and pressure class follow ASME B16.3 at standard (STD) strength, threads are ASME B1.20.1, and the hot dip galvanized coating is ASTM A-153. That is the full spec stack a submittal for threaded malleable iron fittings normally asks for.
7) Which opening is the branch on this reducing tee, and does orientation matter when I install it?
The 2 inch and 1-1/2 inch openings form the run and the 1-1/4 inch is the branch outlet. Order matters when you read the callout: 2 x 1-1/2 x 1-1/4 means the larger run end, the smaller run end, then the branch. Getting it backwards on a reducing tee means the nipple sizes on your riser will not line up.
8) How heavy is this 2 inch galvanized malleable iron reducing tee for hanger and support planning?
The fitting weighs 1.83 lbs. Add that to the filled pipe weight when you space hangers around the branch takeoff.
