3 4 Black Iron 90 Degree Elbow Questions: Size, Threads and Uses

Is this elbow available in a 3/4-inch size?

The listed size range is DN15 (1/2 inch) to DN150 (6 inches), covering the range in which a 3/4-inch configuration is typically specified. Include the required nominal size in your inquiry so the supplier can confirm the exact item for your order.

What do MF threads mean on the elbow?

MF means male and female. One end has an external male thread and the other has an internal female thread. This bidirectional connection supports a direct transition between compatible threaded pipe or fittings and can help simplify a right-angle layout.

Is the fitting black iron or galvanized?

This product is galvanized malleable iron. Its surface treatment is hot-dip galvanizing, which creates a zinc-iron protective layer for corrosion resistance in humid environments. Buyers specifically requiring an uncoated black finish should identify that finish requirement separately when requesting a quotation.

Where can a 90-degree galvanized malleable iron elbow be used?

The listed applications include HVAC, water supply, drainage, fire protection, and industrial piping. The MF 90-degree form suits a layout that must turn the pipe direction at a right angle while joining a male-threaded end to a female-threaded end.

What thread and sealing details should be confirmed before ordering?

The product uses tapered pipe threads, and the listed thread information includes National Pipe Thread standards. The compatible sealing method depends on the project connection and specification. Send the required nominal size, thread requirement, quantity, and application to HEBEI JINMAI CASTING CO.,LTD. before placing an order.
