The adapter for spherical ends with wing nut fastening is a durable and versatile solution designed for demanding steam installations. Manufactured from galvanized steel, it ensures long-lasting resistance to corrosion and mechanical wear, while the integrated polymer or copper insert on the conical surface guarantees a precise seal against the spherical end. Thanks to the practical wing nut, the connection can be tightened or released quickly and effortlessly, without the need for additional tools, making maintenance and assembly exceptionally convenient. Engineered to withstand working pressures up to 18 bar at +210°C saturated steam and operating temperatures up to +230°C, the adapter delivers reliable performance even under extreme conditions. Its unique thread design, larger in the wing nut than in the internal GFB adapter, allows for flexible configuration of various connections, adapting seamlessly to different installation requirements. This makes it an essential component for creating safe, tight, and efficient steam systems where durability, ease of use, and high thermal resistance are crucial.
