FKKH Series Pipe Joint Type With Nut Inside (For Polyurethane Hose With Cloth)

The FKKH Series is a pipe joint type featuring a built-in nut locking structure designed to provide secure connections while maintaining a streamlined appearance. Unlike traditional fittings with externally visible nuts, this integrated design positions the locking mechanism within the body of the joint, resulting in a clean, uncluttered exterior that is well suited for applications where visual simplicity or compact layout is preferred.

The internal nut locking mechanism is specifically engineered for use with woven fabric reinforced polyurethane hoses, commonly referred to as braided PU hoses. These hoses incorporate a reinforcing fabric layer that enhances their ability to withstand pressure and resist expansion under load. The built-in nut engages directly with the hose structure to create a secure clamping effect, helping to prevent slippage or detachment during operation. This design is intended to address the specific requirements of braided hoses, providing reliable retention without the need for external clamping components.

The joint body is constructed from high-quality brass with a nickel-plated finish. This material combination offers good mechanical strength and resistance to pressure, making it suitable for applications where the fitting may be exposed to elevated operating pressures. The nickel plating also provides corrosion resistance, helping to protect the component from moisture, oxidation, and other environmental factors that could affect long-term performance. Additionally, the plated surface contributes to a smooth, uniform appearance that aligns with the clean aesthetic of the overall design.

By integrating the locking mechanism internally, the FKKH Series reduces the number of protruding elements that could interfere with adjacent components or complicate installation in confined spaces. This design approach supports more flexible routing of braided hoses in dense equipment layouts while maintaining the structural integrity of the connection.
