Features of the S-Series breathing tube with swivel connector

This S-Series breathing tube model stands out for its unique expandable structure that goes from a length of 525 mm to 850 mm according to your needs. Manufactured from high-quality polyurethane, it offers superior resistance to chemicals and punctures while remaining extremely lightweight. The main feature of this product is its swivel connector which allows for fluid rotation, preventing the tube from tangling or creating uncomfortable points of resistance. This tube is specifically compatible with 3M Versaflo TR-300, TR-600, and TR-800 series powered respiratory protection systems, ensuring a perfect seal and compliance with current safety standards.

How to install the expandable breathing tube on your powered respirator

The installation of this expandable breathing tube is done intuitively thanks to the 3M Quick Release Swivel system. To begin, insert the end of the swivel connector into the air inlet of your Versaflo hood or visor until you hear a firm click. Then, connect the other end of the breathing tube to the outlet of your TR-600 or TR-300 motorized unit. Ensure that the gaskets are clean and properly in place before starting your device. A visual and manual leak test is recommended after each installation to ensure that purified air circulates without any leaks.

How to maintain the polyurethane breathing tube to prolong its life

To maintain the integrity of your S-Series breathing tube, regular cleaning is essential after each use. Use a soft cloth dampened with warm water and mild soap to wipe the external polyurethane surface. Avoid using aggressive solvents that could degrade the plastic material. When drying, stretch the tube slightly to ensure that no moisture remains trapped in the expandable grooves. Always store your breathing tube in a cool, dry place, away from direct sunlight and heat sources, to prevent premature drying of the polyurethane.

Usage tips for optimal respiratory protection

For maximum safety, always check the condition of your expandable breathing tube before entering a contaminated area. If you notice cracks, holes, or a loss of elasticity, replace the component immediately. It is strongly advised to use a disposable breathing tube cover to protect the polyurethane from paint splashes or abrasive dust, which will greatly facilitate decontamination. Also, ensure that the tube is not pinched by your clothing or safety harness, as this could reduce the airflow necessary for your protection.
