ASC Engineered Solutions 311040000 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 1 x 1 x 1/2 galvanized malleable iron tee?
Two of the ports are 1 inch and the branch is 1/2 inch. All three are female pipe thread (FPT), so it runs 1 inch pipe straight through and takes a 1/2 inch reducing branch off the side, typically for a drop, gauge, drain or small takeoff. No bushing needed at the branch.
2) Will this galvanized tee thread onto standard NPT pipe and nipples?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with any standard NPT male pipe end or nipple in the matching size. Use pipe dope or PTFE tape on the male threads.
3) Is this tee UL Listed and FM Approved for fire sprinkler piping?
Yes, the 1 x 1 x 1/2 malleable iron tee carries UL/FM recognition, so it can be used on fire protection piping where a listed and approved fitting is required. It is a standard pattern galvanized malleable iron fitting, which is what most wet and dry sprinkler branch lines call for.
4) Is this a Class 150 standard fitting or an extra heavy tee?
It is a standard (STD) pattern fitting, dimensioned and pressure rated to ASME B16.3. If your drawing calls for Class 300 extra heavy malleable iron, this is not the right fitting, you need the XH pattern in the same size.
5) Is the galvanizing on this malleable iron tee hot dip, and will it hold up outdoors or in a wet system?
The galvanized coating is applied to ASTM A-153, the hot dip zinc spec for iron and steel hardware, over a malleable iron body made to ASTM A-197. That is the coating normally specified for corrosion resistance on dry and wet sprinkler piping and damp or exterior service. Cut or damaged threads should be touched up with a zinc rich compound.
6) Do I need a reducing bushing to land a 1/2 inch drop off this 1 inch tee?
No. The branch outlet is already 1/2 inch FPT, so a 1/2 inch male nipple or threaded pipe threads straight in. A bushing would only be needed if you were starting from a straight 1 x 1 x 1 tee.
7) Can I use this galvanized tee on a domestic water line?
It is a plumbing-department fitting and threads to standard NPT, so it works on general threaded pipe systems including water service lines run in galvanized or steel pipe. Match it to galvanized pipe rather than mixing with bare black iron in a wet line. For potable water, confirm your local code accepts galvanized malleable iron for the application.
8) What is the part number and shipping weight on the 1 x 1 x 1/2 ASC galvanized tee?
The manufacturer part number is 311040000 and the fitting weighs 0.73 lbs each. Useful if you are pricing out a bulk pull of branch line fittings by weight.
