Air compressor accessory Proline 66386 — maximum inlet pressure 9.3 bar, 1 pc

Proline 66386 is an air compressor accessory designed for connection, adaptation or replacement of existing fittings in pneumatic systems. Rated for a maximum inlet pressure of 9.3 bar and supplied as a single piece per pack, this component is intended for use where the stated pressure limit and compatibility with compressor fittings are required. The part is suited for basic installation, maintenance and repair tasks and can be integrated into setups that require pressure regulation and supply of clean, dry air to pneumatic tools.

Advantages

The accessory provides a clear maximum inlet pressure rating of 9.3 bar, allowing system designers and technicians to match it to compatible compressors. Being supplied as a single unit simplifies inventory and replacement processes. The component is engineered to work with pneumatic tools by helping maintain regulated working pressure and contributing to the delivery of clean, dry air when used with appropriate filtration and drying elements. Its straightforward design makes it easy to install in standard compressor outlets and hose connections.

Suitable for

• Replacement of worn or damaged fittings on portable or stationary compressors
• Basic installation tasks in garages, workshops and construction sites
• Maintenance and repair of pneumatic lines supplying tools such as impact wrenches and air ratchets
• Adaptation of compressor outlets to compatible hoses and regulators within the 9.3 bar limit

Key specifications

• Maximum inlet pressure: 9.3 bar
• Quantity per pack: 1 piece
• Intended use: connection/adaptation/replacement in pneumatic systems
• Compatibility: for use with compressors and pneumatic tools that accept standard fittings and operate within the specified pressure

How to use

Before installation, ensure the compressor is switched off and depressurised. Inspect the mating threads and seals on both the compressor outlet and the accessory to confirm compatibility and absence of damage. Fit the accessory by hand-threading to avoid cross-threading, then tighten to the manufacturer-recommended torque or until a secure, leak-free connection is achieved. After installation, pressurise the system gradually and check for leaks using a soapy water solution or an approved leak detector. Use appropriate filtration and drying equipment upstream if clean, dry air is required for pneumatic tools.

Usage recommendations

Do not exceed the maximum inlet pressure of 9.3 bar. Regularly inspect seals and threads for wear and replace the accessory if any damage or persistent leaks are detected. Combine this accessory with suitable filters, regulators and dryers to ensure clean and dry air delivery to pneumatic tools and to protect downstream equipment.
