Is the DNP PLT4 Leak-Free Hydraulic Quick Coupling, Carbon Steel Socket with Male Thread compatible with other ISO 16028/ISO-F quick couplings?

Yes. The DNP PLT4 Leak-Free Hydraulic Quick Coupling, Carbon Steel Socket with Male Thread is fully interchangeable with other ISO 16028/ISO-F quick couplings. It is built to ISO 16028 (flat-face) specifications, features an external UNF male thread, flat-face design to minimize fluid loss and contamination, and includes the standard safety and sealing features. Its construction and dimensions conform to the ISO-F standard, so it will mate and function correctly with ISO 16028 / ISO-F couplings from other manufacturers, provided correct size and seal material (NBR or Viton) are selected for the application.

Can the DNP PLT4 Leak-Free Hydraulic Quick Coupling, Carbon Steel Socket with Male Thread be used safely at sustained temperatures up to 200°C with Viton seals?

Yes. The DNP PLT4 Leak-Free Hydraulic Quick Coupling, Carbon Steel Socket with Male Thread can be used safely at sustained temperatures up to 200°C if fitted with Viton (FKM) seals. The product description specifies Viton seals are suitable for operation from -15°C to +200°C, and the coupling is designed for demanding hydraulic applications, high pressures (up to 350 bar), and durable operation. Ensure the rest of your system materials and the specific hydraulic fluid are compatible with 200°C operation and verify assembly, installation, and maintenance procedures meet the elevated-temperature conditions.

Additional information

Material	CS – steel (cast iron)

The non-drip quick coupling socket with external UNF thread, built in accordance with ISO 16028, is a reliable solution for demanding hydraulic applications in construction machinery and industrial systems. Engineered to withstand working pressures up to 350 bar, it ensures safe and efficient operation even under significant pressure fluctuations. Its flat-face design minimizes fluid loss and prevents contamination, while the integrated safety pin protects against accidental disconnection. The coupling can be easily operated with one hand, offering convenience and speed during maintenance or equipment changes. Manufactured from high-quality steel with a durable zinc-nickel coating, it guarantees long-lasting resistance to wear and corrosion. Depending on the operating environment, users can choose between NBR seals for temperatures from -25°C to +100°C or viton seals for conditions ranging from -15°C to +200°C. Fully interchangeable with ISO-F quick couplings from other brands, this product provides maximum flexibility, reliability, and performance in hydraulic power transmission.
