ASC Engineered Solutions 311055206 – Frequently Asked Questions
1) What size openings does the ASC 3 x 3 x 1 galvanized malleable iron tee have?
It's a reducing tee: the two run ends are 3 inch and the branch outlet is 1 inch. All three openings are female pipe thread (FPT), so it takes male-threaded pipe nipples on the run and a 1 inch male thread on the branch. Use it where you need to pull a small 1 inch takeoff off a 3 inch line without stepping the main down.
2) Are the threads on this malleable iron tee standard NPT?
Yes. The threads are cut to ASME B1.20.1, which is the standard for NPT pipe threads, so it mates with any standard threaded steel or galvanized pipe nipple of the matching size. The fitting itself is female on all three ports.
3) Is this galvanized tee UL Listed and FM Approved for fire sprinkler work?
It carries UL/FM recognition, so it's acceptable for fire protection piping where the AHJ requires listed and approved fittings. It's a standard weight (STD) malleable iron fitting rated to ASME B16.3, which is the usual class used on threaded sprinkler branch lines and mains.
4) Is the galvanizing on this tee hot dip, and will it hold up outdoors or in a wet system?
The galvanized coating is done to ASTM A-153, the hot dip spec for hardware, so it's a zinc coating suitable for damp and exposed service such as wet sprinkler systems, outdoor piping, and unheated spaces. The body is malleable iron per ASTM A-197.
5) Can I use this on potable water?
This is a galvanized malleable iron tee built to ASME B16.3 with ASTM A-197 iron and A-153 galvanizing. Galvanized iron fittings are normally used on fire protection, compressed air, and industrial or non-potable service. For domestic potable water, most jurisdictions now require a lead-free certified fitting in brass, bronze, or approved plastic, so check what your local code accepts before specifying iron here.
6) Will a 3 x 3 x 1 malleable iron tee interchange with another brand's fitting of the same size?
Dimensionally yes. It's made to ASME B16.3, which fixes center-to-end and thread engagement dimensions for threaded malleable iron fittings, so a 3 x 3 x 1 standard weight tee from any B16.3 manufacturer lays out the same in the pipe run. The threads follow ASME B1.20.1, so nipples cut for one will thread into the other.
7) What is the ASC part number for the 3 x 3 x 1 galvanized malleable iron tee?
Order it as ASC Engineered Solutions model 311055206. Specify the reducing configuration when you order, since 3 x 3 x 1, 3 x 3 x 1-1/4 and 3 x 3 x 2 are separate part numbers and look similar on a jobsite once they're out of the box.
