## Long description

Proline 66345 is an air compressor accessory supplied as a single piece and designed for low-pressure compressor connections. Rated for a maximum inlet pressure of 4 bar, this component is intended for use with small compressors and pneumatic systems where a compact adapter or connection part is required. The accessory supports routine workshop tasks such as connecting air tools, replacing hoses or adaptors, and light maintenance operations that do not require high-pressure components.
Advantages
This Proline accessory provides a simple and reliable solution for low-pressure connections. Its 4 bar maximum inlet pressure rating makes it suitable for light pneumatic setups and reduces the risk of overloading more robust, high-pressure fittings. Supplied as a single piece, it is easy to store and install without additional components. The accessory is compatible with common workshop use cases where a compact, low-pressure fitting is needed.
Suitable for
 Connecting small air compressors to workshop air tools
 Replacing or adapting hoses and fittings in light pneumatic systems

Key specifications
 Maximum inlet pressure: 4 bar
 Quantity in pack: 1 piece
 Intended application: low-pressure compressor connections and adaptions
 Compatibility: designed for small compressors and light pneumatic systems
How to use
Verify that the compressor or pneumatic system operates within the accessory's 4 bar maximum inlet pressure before installation. Ensure mating threads or connection types are compatible and free from damage or debris. Hand-tighten the connection and, if applicable, secure with appropriate tools to the manufacturer's recommended torque to avoid leaks; do not exceed safe tightening to prevent damage. After installation, test the connection at low pressure, inspect for leaks, and only then gradually bring the system up to normal operating pressure within the accessory limit.
Usage recommendations
Use this accessory only in applications that do not exceed 4 bar. Regularly inspect connections for wear, corrosion or damage, and replace the part if signs of deterioration appear. Avoid using the accessory with high-pressure tools or systems. Follow general workshop safety practices when installing or servicing pneumatic connections.
