ASC Engineered Solutions 310053400 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 310053400 black malleable iron tee?
It's a reducing tee with 2-1/2 inch run ends and a 2 inch branch, so the sizes read 2-1/2 x 2 x 2-1/2. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples at every port. That geometry lets you take a 2 inch branch off a 2-1/2 inch line without adding a separate bushing.
2) Is this tee approved for use in a fire sprinkler system?
It carries UL/FM approval, which is what a sprinkler contractor needs for fittings in a listed wet or dry system. The 2-1/2 x 2 x 2-1/2 reducing pattern is a common cross-main to branch-line take-off size. Standard weight class, threaded ends to ASME B1.20.1.
3) What is the difference between a black malleable iron tee and a galvanized one?
Same casting, different coating. Black malleable iron like this 2-1/2 x 2 x 2-1/2 tee is the standard choice for closed systems that stay wet or dry inside: sprinkler mains, steam, natural gas piping, and hydronic heating. Galvanized is what you reach for on potable water or damp, exposed locations where the zinc coating fights corrosion. Don't use black iron on domestic water lines.
4) What pressure class is this 2-1/2 inch malleable iron tee?
Standard weight (Class 150) per ASME B16.3, which governs both the dimensions and the pressure rating of the fitting. Castings are ASTM A-197 malleable iron. If your drawing calls for extra heavy, this is not the fitting; you'd need a Class 300 pattern.
5) Will this reducing tee line up with the dimensions on my piping drawing?
Center-to-end dimensions follow ASME B16.3, the dimensional standard for threaded malleable iron fittings, so it drops into a layout spec'd to that standard and interchanges with any other B16.3 standard-weight 2-1/2 x 2 x 2-1/2 threaded tee regardless of who cast it.
6) Do I need a bushing to take a 2 inch branch off my 2-1/2 inch main?
Not with this fitting. The branch port is already 2 inch FPT while both run ends are 2-1/2 inch FPT, so it reduces at the tee itself. That saves you a reducing bushing and one more threaded joint to seal and inspect.
