ASC Engineered Solutions 311037600 – Frequently Asked Questions
1) What size openings does the ASC 1/2 x 3/8 x 3/8 galvanized malleable iron tee have?
It's a reducing tee with one 1/2 inch opening and two 3/8 inch openings. All three ends are female pipe thread (FPT), so it threads onto male-threaded nipples or pipe ends, not onto female ports. Use it where a 1/2 inch run needs to step down to 3/8 inch branches.
2) Will this galvanized malleable iron 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 NPT-threaded steel or iron pipe and nipples of the matching size. Thread sealant or PTFE tape is still required on the joint; none is supplied with the fitting.
3) Is a galvanized malleable iron tee OK for a wet sprinkler line, or do I need something else?
This tee is UL/FM recognized, which is what a fire protection inspector looks for on threaded fittings in a sprinkler system. It's standard (STD) pressure class per ASME B16.3 and hot dip galvanized to ASTM A-153, so it suits wet systems and damp locations. For gas and general threaded steel piping it works the same way; black iron is the usual choice there instead of galvanized.
4) Difference between galvanized and black malleable iron tees for plumbing work?
The iron body is the same, ASTM A-197 malleable iron built to ASME B16.3 dimensions. The difference is the coating: this one carries a hot dip zinc galvanized finish per ASTM A-153, which resists corrosion in water service and outdoor or damp runs. Black fittings have no coating and are normally kept to gas, dry systems, and interior runs where moisture isn't a factor.
5) Will this reducing tee interchange with another brand's 1/2 x 3/8 x 3/8 galvanized tee already in my run?
Yes, as long as the other fitting is also a Class 150 style threaded malleable iron tee. Both center-to-end dimensions and thread engagement are set by ASME B16.3 and ASME B1.20.1, so a same-size fitting built to those standards drops into the same layout without re-cutting nipples.
6) What is the ASC part number and weight on the 1/2 x 3/8 x 3/8 galvanized tee?
The manufacturer part number is 311037600, and each fitting weighs 0.29 lbs. That weight is useful when you're figuring hanger spacing or loading on a long branch of small threaded fittings.
