Female Metric Coupling

This female metric coupling features M20 x 1.5 threaded connections on both ends, so it's designed for symmetrical metric hydraulic line connections using that thread size.

For tying two matching metric lines together, it’s a straight steel coupling with M20 x 1.5 female threads on both ends, so it mates to M20 x 1.5 male fittings on each side with no thread conversion.

Correct on both counts. Both sides carry an M20 x 1.5 female metric thread, so you're looking at a symmetrical coupling all the way through. No thread conversion needed, no adapters required. If your line connections on each end are male M20 x 1.5, this fits right in between them and keeps everything consistent.
