ASC Engineered Solutions 311042600 – Frequently Asked Questions
1) What size are the three openings on this galvanized malleable iron reducing tee?
The run is 1-1/4 inch on both ends and the branch reduces to 3/4 inch, so it's a 1-1/4 x 1-1/4 x 3/4 tee. All three openings are female pipe thread (FPT), meaning you thread male-end pipe or nipples into it. Use it where you're taking a 3/4 inch branch off a 1-1/4 inch line without adding a separate bushing.
2) Is this tee approved for fire sprinkler piping?
It carries UL/FM approval, so it is acceptable on fire protection piping as well as general plumbing and mechanical work. Class 150 standard pattern per ASME B16.3.
3) Galvanized or black malleable iron tee, which one do I want?
Galvanized is the right call for domestic water, wet outdoor runs, and anywhere corrosion is a concern; this one is hot dip galvanized to ASTM A-153 over ASTM A-197 malleable iron. Black malleable is the usual choice for gas and for dry sprinkler-free interior runs. Don't mix galvanized fittings into a line where the spec calls for black.
4) Do I need a bushing to get from 1-1/4 inch down to 3/4 inch on the branch?
No. The branch is already tapped 3/4 inch FPT, so you thread 3/4 inch pipe straight in. That saves a reducing bushing and one more leak path at the joint.
5) How heavy is a 1-1/4 x 1-1/4 x 3/4 malleable tee for takeoff and freight?
About 1.1 lbs each. Worth knowing when you're pricing a bulk order of fittings or figuring hanger spacing on a threaded run.
6) What is the ASC Engineered Solutions part number for this reducing tee?
Order it as model 311042600 from ASC Engineered Solutions, a galvanized malleable iron 1-1/4 x 1-1/4 x 3/4 tee.
