Bspp Male X Bspt Male Nipple

It adapts between those two thread types in a straight steel nipple. One end is 1 inch BSPP male with a G 1 - 11 callout, and the other end is 3/4 inch BSPT male with an R 3/4 - 14 callout.

That's exactly what this fitting handles. One end is 1-inch male BSPP (G 1 - 11) and the other is 3/4-inch male BSPT (R 3/4 - 14), so it bridges those two thread standards in a straight configuration. Both ends are male, so you'd be threading each side into a female port or coupling on your equipment. Steel construction, 41mm wrench flat, and just under 47mm overall length.

This steel fitting should work fine for most hydraulic applications. Just make sure the oil is compatible with steel to prevent any corrosion over time.
