Is the DIN quick coupling socket with female thread PDV1 for agricultural machinery compatible with ISO-A or ISO-B couplings?

The DIN quick coupling socket with female thread PDV1 for agricultural machinery is not compatible with ISO-A or ISO-B couplings. The product description states it features unique dimensions tailored to the manufacturer’s standard, unlike ISO-A and ISO-B couplings, so it will not interchange with those ISO types.

Is the DIN quick coupling socket with female thread PDV1 for agricultural machinery compatible with other manufacturers’ quick couplings that follow non-ISO dimensions?

The DIN quick coupling socket with female thread PDV1 for agricultural machinery is not compatible with quick couplings from other manufacturers that follow non‑ISO dimensions. The product description states it uses unique, manufacturer‑specific dimensions rather than ISO‑A or ISO‑B standards. Because coupling compatibility depends on exact mating dimensions, thread form and sealing geometry, mixing PDV1 with non‑ISO couplings risks poor sealing, leakage, pressure loss or mechanical damage—even at rated pressures up to 400 bar. To ensure safe, reliable connections, use PDV1 only with mating couplings specified by the same manufacturer or explicitly certified as compatible with the PDV1 non‑ISO dimensions.
