DNP combines sophisticated complex technology, highly skilled and experienced operators, tight production and assembly controls, and systematic vigorous testing in order to produce a vast range of superior couplings.

The range consists of over 60 varieties of couplings, including ISO A, ISO B, flat face, screw/ ISO 14541, and push-pull, with working pressures up to 1500 bar. It also includes multi-coupling plates which allow simultaneous coupling and uncoupling of a certain number of hydraulic and/or electrical lines.

• ISO 9002 Quality Assurance.
• Interchangeable other major manufacturers.
• Selected ranges (flat face – PVT4 BOP, PVTX BOP, PST4 BOP and ISO B – PBV1 BOP) come with Lloyds registered approval. The range is specially designed for blow-out preventer accumulator systems in the oil and gas market
