General
Material	Stainless steel 304 as standard; 316 available on request

The coupler consists of a male plug and a female socket, both with an integrated self-sealing valve that stops flow when disconnected. The stainless steel construction provides corrosion resistance for water, oil, and gas applications. The self-sealing mechanism allows connection and disconnection under pressure without tools, reducing downtime and spillage. Typical uses include hydraulic lines, pneumatic systems, and process piping. When requesting a quote, specify: size (DN), thread type and size (RC, R, or NPT), material (stainless steel grade if required), seal material, quantity, and packaging requirements. Additional parameters such as pressure rating, temperature range, and flow rate should be stated if critical to your application. This ensures the supplier can provide a suitable offer.
