ASC Engineered Solutions 311040802 – Frequently Asked Questions
1) Which port on the ASC Engineered Solutions 1 x 3/4 x 3/4 galvanized malleable iron tee is the 1 inch one?
It's a reducing tee with one 1 inch opening and two 3/4 inch openings. Convention on a reducing tee is run x run x branch, so the 1 inch and one 3/4 inch form the run and the remaining 3/4 inch is the branch outlet. All three openings are female pipe thread (FPT), so the fitting takes male-threaded pipe nipples on every port.
2) Is this tee approved for fire sprinkler piping?
It carries UL/FM approval, which is the listing fire protection contractors and inspectors look for on threaded fittings in sprinkler systems. It is a standard-weight (STD) galvanized malleable iron fitting to ASME B16.3 for both dimensions and pressure rating.
3) Should I use a galvanized tee or a black malleable iron tee on this job?
Galvanized is the choice where moisture or corrosion is in play: wet sprinkler piping, water service, outdoor or damp mechanical rooms. The zinc coating here is hot-dip to ASTM A-153. Black malleable iron is the usual pick for gas and for dry indoor service where the coating buys you nothing. Both share the same ASME B16.3 dimensions, so switching between them doesn't change your takeouts.
4) Is this a standard weight or extra heavy fitting, and what pressure class does that mean?
Standard weight (STD), which in the ASME B16.3 malleable iron system is the Class 150 fitting. Both its pressure rating and its dimensions are governed by B16.3. If your drawing calls for Class 300 extra heavy, this is not the fitting for that line.
5) Do I need thread sealant or tape with this fitting, or does it seal on its own?
NPT threads seal on the thread interference, not on a gasket, so you need pipe dope or PTFE tape on the male threads going in. Nothing is supplied with the fitting; it is the tee only, and you provide the nipples and the sealant. Check that the sealant you use is rated for the service, since UL/FM sprinkler work and potable water each have their own approved products.
6) What is the material grade on this ASC malleable iron tee?
Malleable iron produced to ASTM A-197, the standard grade for cupola malleable iron pipe fittings, then hot-dip galvanized to ASTM A-153. That combination is what a spec writer is asking for when the drawing says galvanized malleable iron fittings. Each fitting weighs 0.75 lbs.
