ASC Engineered Solutions 318907003 – Frequently Asked Questions
1) Is this black iron bushing approved for fire sprinkler piping?
It carries UL/FM approval and is black malleable iron built to ASME B16.3, which is the class of fitting used on black steel sprinkler mains and branch lines. Confirm the approval covers your specific service with your AHJ as always, but the listing itself is UL/FM.
2) Can I use a black malleable iron bushing on a domestic water line?
No. Black malleable iron is for gas, fire protection, steam, air, and non-potable service. The black finish has no corrosion protection against wet potable water, and it is not a lead-free potable fitting. For potable water use a galvanized, brass, or copper reducing bushing instead.
3) Is this a standard or extra heavy pattern bushing, and what class is it?
Standard pattern (STD), dimensioned and pressure rated to ASME B16.3. That is the Class 150 malleable iron fitting family used on threaded black pipe. If your spec calls for extra heavy or Class 300, this is not the fitting.
4) What material spec does this ASC bushing meet for submittals?
Castings are to ASTM A-197 malleable iron, with dimensions and pressure rating to ASME B16.3 and threads to ASME B1.20.1. Those three callouts cover most mechanical submittal sheets for threaded black iron fittings. Manufacturer part number is 318907003.
5) Do I need a wrench flat to install this reducing bushing, or is it a flush type?
It is a hex bushing, so the male end has a wrench hex cast onto it. You tighten it with a standard pipe or open end wrench before landing the 1 inch fitting. A face or flush bushing would need an internal hex key instead, so allow clearance for the wrench flats when you lay out tight fitting groups.
