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

The FKK Series is a pipe joint type designed with an internal nut locking mechanism specifically intended for use with woven polyurethane hoses, commonly referred to as braided PU hoses. This specialized configuration addresses the unique requirements of such hoses, which feature a reinforcing fabric layer that provides additional strength and resistance to pressure-related expansion.

The internal nut locking mechanism operates by tightening around the hose to create a secure grip. Once fastened, the nut generates strong clamping force that helps hold the hose firmly in place, reducing the likelihood of detachment or slipping even under conditions where vibration or pressure fluctuations may be present. This design is particularly suited for applications where maintaining a reliable connection over extended periods is important.

The connector body is constructed from high-quality brass with a nickel-plated finish. This material selection offers good mechanical strength while providing resistance to corrosion, helping the joint maintain its structural integrity in environments where exposure to moisture, chemicals, or other corrosive elements may occur. The nickel plating also contributes to a smooth surface finish that supports consistent performance over time. The robust construction of the body allows the joint to withstand higher pressure conditions compared to standard fittings not reinforced for such applications.

Installation involves inserting the woven polyurethane hose into the joint and securing it by tightening the internal nut. This method creates a mechanical lock around the hose without requiring specialized tools or complex procedures. The resulting connection is intended to remain stable under operating conditions, helping to prevent gradual loosening that could lead to leakage or disconnection.

The FKK Series is suited for pneumatic systems that utilize braided PU hoses, particularly in applications where pressure resistance, secure clamping, and corrosion-resistant materials are required. Its internal nut design offers a practical approach to achieving dependable connections in equipment where hose retention and long-term reliability are priorities.
