ASC Engineered Solutions 311088405 – Frequently Asked Questions
1) Is the ASC 1-1/2 x 1 galvanized malleable iron reducer female threaded on both ends?
Both ends are FPT, so it's a female-to-female bushing-style reducer: 1-1/2 inch FPT on the large end, 1 inch FPT on the small end. Threads are NPT per ASME B1.20.1, so it mates with standard male-threaded steel or iron pipe nipples on both sides. If your run has male threads on one side and you need to step down, you'd need a bushing or a nipple, not this coupling-style reducer.
2) Can I use this galvanized malleable iron reducer on a fire sprinkler line?
It carries a UL/FM listing, which is what an AHJ looks for on fire protection piping. It's a standard pressure class malleable iron fitting made to ASME B16.3 for both dimensions and pressure rating, with NPT threads to ASME B1.20.1. Confirm the pressure class against your system design before you commit it to a sprinkler main.
3) Is the galvanizing on this ASC reducer hot dip, and will it hold up outdoors?
The zinc coating is specified to ASTM A-153, the hot dip galvanizing standard for iron and steel hardware, giving it a heavier coating than an electroplated fitting. That's why galvanized malleable is the usual pick for exterior, damp, or unheated spaces and for domestic water runs in older galvanized steel systems.
4) What is the ASC reducer made of, and can I thread it onto black iron pipe?
It's malleable iron to ASTM A-197 with a galvanized finish. The NPT threads mate with black steel pipe just fine mechanically, but mixing galvanized and black in the same wet run is generally avoided on potable and heating systems. For a black iron gas or fuel line, use a black malleable fitting instead and keep the system consistent.
5) Will this 1-1/2 x 1 reducer interchange with another manufacturer's malleable reducer of the same size?
Dimensionally yes, because it's built to ASME B16.3 with ASME B1.20.1 taper pipe threads, which is the same envelope any conforming 1-1/2 x 1 malleable reducer is built to. What you should match separately is the class (this one is standard, not extra heavy) and the UL/FM listing if the job is fire protection.
6) What part number do I order for the ASC 1-1/2 to 1 inch galvanized reducer?
Order ASC Engineered Solutions model 311088405. That's the 1-1/2 inch by 1 inch galvanized malleable iron reducer, standard pattern, and it weighs 0.91 lbs each for shipping or takeoff purposes.
