ASC Engineered Solutions 311045009 – Frequently Asked Questions
1) Will this tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with any standard threaded steel or iron pipe and nipples of the matching size. Use pipe dope or PTFE tape on the male threads.
2) Is this galvanized tee approved for fire sprinkler piping?
The fitting carries UL/FM approval, so it can be used on listed fire protection piping. It's a standard pattern (STD) malleable iron fitting built to ASME B16.3 for both dimensions and pressure rating.
3) Can I use this reducing tee to branch a 1-1/4 inch line off a 1 inch run?
No, not that way around. The two matched 1 inch ends form the run and the 1-1/4 inch is the odd opening. If you need a 1 inch branch taken off a 1-1/4 inch run, you want a 1-1/4 x 1-1/4 x 1 tee instead. This one suits a 1 inch run opening up to a 1-1/4 inch takeoff, or a 1-1/4 inch line reducing into a 1 inch run depending on how you orient it.
4) Galvanized or black malleable iron tee, which one do I want?
Galvanized is the one to use on wet lines, exposed runs, and anywhere corrosion is a concern, including domestic water and wet sprinkler systems. This tee is hot-dip galvanized to ASTM A-153. Black malleable iron is the usual choice for dry gas piping and dry systems. Don't mix a galvanized fitting onto black pipe if the job spec calls for a matched system.
5) What is the body material and does it meet a spec I can put on a submittal?
Malleable iron to ASTM A-197, galvanized per ASTM A-153, with dimensions and pressure rating to ASME B16.3 and NPT threads to ASME B1.20.1. That's the full set of citations a submittal or MRO spec sheet normally asks for on a threaded iron fitting.
6) How much does one of these 1 x 1 x 1-1/4 malleable tees weigh?
0.97 lbs each. Useful if you're calculating hanger spacing and support loads on a long threaded run, or estimating freight on a bulk fitting order.
7) What is the ASC part number for the 1 x 1 x 1-1/4 galvanized malleable tee?
ASC Engineered Solutions part number 311045009. That's the number to quote when matching fittings across a job or reordering for stock.
