Do you work to the OCP specification?

Designed to the OCP UQD Specification Rev 1.0, dated 2020-09-04, and tracking the merged UQD + UQDB draft at v2.0.1, 2025-04.

What pressure and temperature does the interface take?

100 psi working pressure and a 17–65 °C operating window are specification requirements; industry manifold designs reach 580 psi.

How many connect and disconnect cycles?

The specification requires 5,000 cycles on both the socket and the plug (per OCP UQD specification).
