ASC Engineered Solutions 310529805 – Frequently Asked Questions
1) What thread type are the openings on the ASC 3/4 inch black malleable iron cross?
All four openings are 3/4 inch FPT, female NPT taper pipe thread cut to ASME B1.20.1. That means it threads directly onto standard 3/4 inch male-threaded black steel pipe nipples on every branch, no adapters. It's a straight cross, so all four ports are the same size.
2) Is this 3/4 inch malleable iron cross rated for fire sprinkler work?
It carries UL/FM approval, which is what an inspector looks for on sprinkler piping. It's an extra heavy (XH, also called Class 300) malleable iron fitting with pressure ratings per ASME B16.3, so it belongs on the higher pressure side of black iron work rather than low pressure gas or air only.
3) Can I use a black malleable iron cross on a domestic water line?
No. Black malleable iron is uncoated and will rust in potable water service. Use galvanized or a copper/CPVC system for domestic water. Black fittings like this one are for gas, air, sprinkler, and closed-loop hydronic piping where the fluid is not potable.
4) What material spec does this ASC Engineered Solutions cross meet?
The casting is malleable iron to ASTM A-197, with dimensions to ASME B16.3. Those are the two callouts most commercial specs and submittals ask for on threaded iron fittings, so it drops into a spec sheet that names either one.
5) When should I use a cross instead of two tees on a 3/4 inch black iron line?
A cross gives you two opposed branches off a single run at one point, which saves a nipple and a fitting and keeps the assembly short where you're tight to a joist or wall. Two tees are the better call when the branches need to be offset or take off at different elevations. This one is 3/4 inch on all four ports, so it only works where run and both branches are the same size.
6) How much does the 3/4 inch XH black cross weigh?
1.25 lbs each. Worth knowing if you're pricing freight on a bulk order or figuring hanger loads on a long threaded assembly.
