ASC Engineered Solutions 311088207 – Frequently Asked Questions
1) Are both ends of the ASC Engineered Solutions 1-1/2 x 1-1/4 galvanized malleable iron reducer female threaded?
Both ends are FPT, so the reducer takes male pipe threads on each side. It goes from 1-1/2 inch down to 1-1/4 inch, and the threads are cut to ASME B1.20.1 (NPT), so it mates with standard NPT male ends on steel or galvanized pipe nipples.
2) Can I use this galvanized malleable iron reducer on a fire sprinkler line?
It carries UL/FM approval, which is the listing fire protection contractors need for sprinkler piping. It is a threaded malleable iron reducing coupling, standard pressure class, built to ASME B16.3 for both dimensions and pressure rating.
3) Is this reducer standard class or extra heavy (150 vs 300)?
Standard class. The fitting is rated STD, with pressure ratings per ASME B16.3, which is the 150 class malleable iron range. If the drawing calls for 300 class extra heavy, this is not the fitting for that spec.
4) Will a galvanized malleable iron reducer hold up outdoors or in a damp mechanical room?
The galvanized finish is hot dip to ASTM A-153, which is a heavier zinc coating than electroplating and is what gets specified for wet, outdoor, and corrosive service. The body itself is malleable iron to ASTM A-197.
5) What is the difference between this threaded reducer and a bushing for going 1-1/2 to 1-1/4?
This one is a reducing coupling: female threads on both ends, so it joins two male pipe ends and keeps the run close to full flow area. A bushing is male on the large side and female on the small side, and screws into a fitting instead of joining two pipes. Pick the coupling when you are joining two nipples or pipe ends of different size; pick a bushing when you are reducing at a tee, valve, or elbow port.
6) How much does the 1-1/2 x 1-1/4 galvanized malleable iron reducer weigh for a takeoff?
0.93 lbs each. Useful if you are pricing freight on a bulk MRO or sprinkler order where several dozen fittings go on one line item.
7) Do I need pipe dope or PTFE tape with this fitting?
Yes. Threads are tapered NPT per ASME B1.20.1, and tapered threads seal on the thread engagement, so a thread sealant or PTFE tape on the male ends is required. Galvanized malleable iron is a mechanically joined fitting, not welded or soldered.
8) What part number should I order for the ASC 1-1/2 x 1-1/4 galvanized reducer?
The manufacturer part number is 311088207, an ASC Engineered Solutions galvanized malleable iron reducing coupling, 1-1/2 inch by 1-1/4 inch, FPT both ends.
