ASC Engineered Solutions 311035802 – Frequently Asked Questions
1) Is the ASC 1/4 x 1/4 x 1/8 galvanized malleable iron tee threaded female on all three openings?
All three openings are female pipe thread (FPT). The run is 1/4 inch on both ends and the branch reduces to 1/8 inch, so it takes male-threaded pipe or male fittings in every port. Threads are cut to ASME B1.20.1, the standard NPT thread spec, so it mates with any NPT male thread of the matching size.
2) Which port on this reducing tee is the smaller 1/8 inch one?
The reduction is on the branch, not the run. Size 1 and Size 2 are both 1/4 inch and Size 3 is 1/8 inch, so pipe passes straight through at 1/4 inch and the take-off tapping is 1/8 inch. That is the usual arrangement for dropping a gauge, sensor, or small bleed line off a 1/4 inch line.
3) Is this ASC tee UL listed and FM approved for fire protection work?
Yes, it carries UL/FM recognition, which is what an inspector looks for on a sprinkler or fire protection line. It is a standard weight (STD) malleable iron fitting rated to ASME B16.3.
4) Can I use a galvanized malleable iron tee on a water line, or should it be black iron?
Galvanized is the right pick for water. This tee is malleable iron with a hot dip galvanized finish applied to ASTM A-153, which is the coating spec that resists corrosion in wet service. Black malleable iron of the same pattern is what you use on gas and dry lines. Same dimensions either way, the finish is the difference.
5) Will this tee interchange dimensionally with another brand's 1/4 x 1/4 x 1/8 malleable tee?
It is built to ASME B16.3, the dimensional standard for threaded malleable iron fittings, so center-to-end and thread engagement match any other B16.3 fitting of the same size and class. Swapping it in for a same-size reducing tee from another manufacturer will not change your pipe cut lengths.
6) Is this a standard class or extra heavy malleable iron fitting?
Standard weight, listed as STD, with its pressure rating set by ASME B16.3. If your spec calls for 300 lb extra heavy malleable iron, this is not the fitting for it, you need the XH pattern in the same 1/4 x 1/4 x 1/8 configuration.
7) What is the part number and weight on the ASC 1/4 x 1/4 x 1/8 galvanized tee for my purchase order?
Order it as ASC Engineered Solutions part 311035802. Each fitting weighs 0.14 lbs, which is useful if you are pricing freight on a bulk MRO order of small fittings.
8) Do I need thread sealant with this galvanized malleable tee?
Yes. The ports are tapered NPT female threads cut to ASME B1.20.1, and tapered pipe thread seals on the thread flanks, so it needs PTFE tape or a pipe dope rated for your media. Nothing is supplied with the fitting, it is the tee only.
9) What grade of malleable iron is this fitting made from?
The casting is produced to ASTM A-197, the specification for cupola malleable iron used in pressure pipe fittings, then hot dip galvanized to ASTM A-153.
