ASC Engineered Solutions 310543400 – Frequently Asked Questions
1) Is the 1-1/4 x 3/4 black malleable iron reducer female threaded on both ends?
Both ends are FPT (female pipe thread), so it threads onto male pipe ends or male-threaded nipples on each side. Threads are cut to ASME B1.20.1, the standard NPT thread spec, so it mates with any standard NPT male thread. The large end takes 1-1/4 inch pipe, the small end 3/4 inch.
2) Is a black malleable iron reducer OK for a domestic water line?
No. Black malleable iron is for gas, fire protection, steam, and compressed air, not potable water, where the uncoated iron corrodes. For a water branch use a galvanized malleable reducer or a brass or copper reduction instead. This fitting has a black finish with no protective coating.
3) Do I need a bushing or a coupling if I'm reducing 1-1/4 inch pipe to 3/4 inch?
A reducing coupling like this one does the job in a single fitting, female on both ends, so you thread 1-1/4 pipe into one side and 3/4 into the other. A hex bushing would be the alternative, but a bushing is male on the large end and screws into a fitting rather than onto pipe. If you are joining two lengths of threaded pipe directly, the reducer is the part you want.
4) What iron grade is this ASC reducer made from?
The casting is malleable iron produced to ASTM A-197, the standard grade for cupola malleable iron pipe fittings. Dimensions and pressure class follow ASME B16.3 and the threads ASME B1.20.1, which is the usual spec trio a mechanical submittal asks for.
5) What is the part number and weight on the ASC 1-1/4 x 3/4 extra heavy black reducer?
The manufacturer part number is 310543400 from ASC Engineered Solutions, and each fitting weighs 1.16 lbs. That weight is useful when you are figuring hanger spacing or freight on a bulk order of threaded fittings.
