Series PD Coupling - Female UNF Thread

Diagnostic couplings provide easily accessible test points for performance testing of hydraulic and pneumatic systems. Easily incorporated into original equipment or retrofitted to existing circuits, PD plugs meet or exceed SEA J 1502 and ISO 15171-1 design and performance specification. Carbon steel for couplers. High tensile steel for plugs. For water applications also available in brass on request. Ball locking mechanism. Flush-faced poppet valve for a minimal air inclusion when connecting, minimal fluid loss during disconnection and for an easy cleaning. The sealing and locking groove are induction hardened to resist mechanical abuse and brinelling, whilst avoiding toughness. A safety sleeve lock prevents accidental disconnection. Push-to-connect operation allows single handed operation when connecting the coupling.

Working Temperature (celsius):

-40°C up to +110°C (NBR)
Depending on the medium. Special seals are available on request
