ASC Engineered Solutions 311040604 – Frequently Asked Questions
1) What do the three sizes mean on a 1 x 3/4 x 1 galvanized malleable iron tee?
On this ASC Engineered Solutions reducing tee the two run ends are 1 inch and the branch outlet is 3/4 inch. So it carries a 1 inch line straight through and takes a 3/4 inch takeoff off the side. All three openings are female pipe thread.
2) Are the ends on this ASC tee female threaded, and what thread standard do they follow?
All three openings are FPT, female pipe thread, cut to ASME B1.20.1 (NPT). It threads onto male-threaded pipe nipples or male adapters, so you'll need a nipple or a male fitting on each side. It does not accept sweat, push-fit, or grooved pipe.
3) Can I use a galvanized malleable iron tee on a fire sprinkler line?
This tee is UL/FM recognized, which is what an AHJ looks for on fire protection piping. It is standard weight malleable iron per ASTM A-197 with pressure ratings to ASME B16.3. Confirm the pressure class against your hydraulic calculation for the system.
4) Will this tee interchange with another manufacturer's 1 x 3/4 x 1 malleable iron tee?
Yes. Dimensions are per ASME B16.3 and threads per ASME B1.20.1, so the center-to-end lay length and thread engagement match any other standard-weight 1 x 3/4 x 1 malleable iron tee built to those same standards. It drops into an existing run without re-cutting nipples.
5) Is a galvanized tee the right choice for potable water?
Galvanized malleable iron is a hot-dip zinc coated fitting per ASTM A-153, built for the corrosion resistance wet lines need, and it's commonly used on water service, fire protection, and general plumbing. For potable service, check your local code, since many jurisdictions now require lead-free-certified materials on drinking water lines. On non-potable water, air, and fire lines, galvanized is the standard answer where you don't want black iron rusting.
6) Should I use a galvanized tee or a black malleable iron tee?
Go galvanized where moisture is involved: water lines, wet sprinkler systems, outdoor or damp mechanical rooms. Black malleable iron is the usual pick for gas and dry systems, where the zinc coating buys you nothing. This ASC fitting is the galvanized version, hot-dip coated to ASTM A-153. Don't mix the two in the same wet run if you can avoid it.
7) What is the part number and weight for the ASC 1 x 3/4 x 1 galvanized tee?
The manufacturer part number is 311040604 and the fitting weighs 0.81 lbs. Useful if you're pricing freight on a pallet of fittings or building a takeoff list.
