Brass Pipe Fitting, 1-1/4 x 3/4 Inch Hex Bushing

For stepping down between pipe thread sizes, this hex bushing is the 1-1/4 x 3/4 size, so it is meant for that exact reduction from 1-1/4 to 3/4.

Yes, that's correct. This brass fitting adapts from a 1-1/4 inch pipe down to a 3/4 inch pipe.

For hydraulic connections and fluid transfer, absolutely. This hex bushing is designed to adapt a 1-1/4 inch connection down to a 3/4 inch connection.

Brass is actually a solid choice for wet and humid conditions. It resists corrosion well, which is why it gets used so often in hydraulic connections and industrial setups where moisture is a regular factor. This particular bushing is all brass construction, so long-term exposure to humidity shouldn't cause the kind of deterioration you'd see with plain steel fittings.
