ASC Engineered Solutions 310016605 – Frequently Asked Questions
1) What is the difference between a street elbow and a regular 90 degree elbow?
A street elbow has one female threaded end and one male threaded end, so it can thread directly into a fitting or valve without a nipple in between. The ASC Engineered Solutions 1 inch black malleable iron 90 street ell is FPT on one end and MPT on the other. A standard 90 elbow is female on both ends and needs a close nipple to make that same connection, which adds a joint and takes up more space. Use the street ell where you are tight on clearance or want one less potential leak point.
2) Will this 1 inch street elbow thread onto standard 1 inch black iron pipe?
Yes. Both ends are 1 inch and cut to ASME B1.20.1, which is the NPT tapered pipe thread standard used on standard black iron and galvanized steel pipe. The female end takes a 1 inch male pipe end or nipple; the male end threads into any 1 inch FPT port, coupling, tee, or valve.
3) Can I use a black malleable iron street elbow on a potable water line?
No. Black malleable iron fittings are for gas, fire protection, steam, air, and non potable applications. The black finish is a mill coating, not a corrosion barrier for water service, and it will rust in wet potable lines. For domestic water, use a galvanized or copper/brass fitting instead. This one is a black finish malleable iron fitting to ASTM A-197.
4) Is this the right fitting for a natural gas or propane line?
Black malleable iron 90 street ells are the standard fitting for threaded gas piping, and this one is made to ASTM A-197 malleable iron with ASME B1.20.1 NPT threads and B16.3 dimensions. Joints still need an approved pipe thread sealant or tape rated for gas, applied to the male threads only. Always follow the local fuel gas code for the run.
5) Can I swap a 1 inch black street ell with a galvanized one of the same size?
Dimensionally yes, since both follow ASME B16.3 and use B1.20.1 NPT threads in 1 inch, so the make up is the same. The difference is service: galvanized is the choice for water and damp or outdoor runs, black for gas, fire protection, and dry service. Do not mix black and galvanized in the same wet run if you want to avoid accelerated corrosion at the joints.
6) What is the part number and weight for ordering this 1 inch black street elbow?
Order by manufacturer part number 310016605 from ASC Engineered Solutions. Each fitting weighs 0.62 lbs, which is useful when you are figuring freight or hanger loads on a large fitting order.
