The MUBEA self-locking clamp with a range of 19.3-21.6 mm (manufacturer's symbol MUB-ST/20) is a robust clamp made from spring steel band. This self-tightening fastening clamp offers stable clamping force that remains even in the face of temperature variations and pressure differences. As a result, it ensures the seal of the connection, eliminating fluid leaks and gas leaks in various working conditions.

The MUBEA self-locking clamp is widely used in LPG gas installations, as well as in control hydraulics, fuel systems, air conditioning systems, supercharging air systems, and air intake systems.

The material used for producing the MUBEA self-locking clamp is high-quality spring steel alloy 51 CrV4, known for its high strength and fracture resistance, especially in low temperatures. Additionally, the clamp has an eco-friendly surface coating that is free from chrome VI and corrosion-resistant, in compliance with the latest standards. The working temperature range is from -40°C to +210°C.
