DNP says they are interchangeable with their respective competitor’s series (Cejn) 115 and 116.

With internal and external standard NPT and BSP connection threads, they can also be produced with 37 ° (SAE) or 100 ° (BSP) metal sealing threads upon request.

These couplings have been produced in a single size, DN ISO 6.3, therefore the products are suitable in applications where an ultra-high working pressure is required.
