3M Versaflo PAPR TR-300 Breathing Tube, BT-20S and BT-20L
The 3M Versaflo breathing tube (models BT-20S and BT-20L) is a genuine replacement part for 3M Versaflo TR-300 PAPR systems. Made from flexible polyurethane, it ensures the circulation of filtered air between the motorized blower and the facepiece worn by the operator during construction, manufacturing, or general maintenance work.
3M purchase code: 7100296066 (BT-20S) / 7100296133 (BT-20L), model: BT-20S / BT-20L
Available in two lengths adapted to the wearer's morphology: BT-20S for S/M builds and BT-20L for M/L builds. This tube complies with NIOSH requirements for PAPR systems in the Versaflo TR-300 range. Sold individually, available as a special order with an estimated production lead time of 11 calendar days.
A breathing tube in good condition is essential for maintaining airflow and protecting the operator. Regularly inspect the tube for cracks, kinks, or discoloration. A damaged tube must be replaced immediately before any use of the respirator.

FAQ — frequently asked questions about this product
What is the difference between the BT-20S and BT-20L?
The BT-20S is a short tube designed for S/M body types, while the BT-20L is a longer tube for M/L builds. The choice depends on the wearer's size and the configuration of the Versaflo TR-300 system used. Both models are compatible with the same motorized blower and deliver identical performance in terms of airflow and protection level.
Is this tube compatible with TR-600 or TR-800 systems?
No, the BT-20S and BT-20L tubes are specifically designed for the 3M Versaflo TR-300 range. TR-600 or TR-800 systems require tubes from their respective series. Using an incompatible tube can compromise the minimum required airflow and reduce the effectiveness of respiratory protection. Contact the Sylprotec team to identify the correct tube for your system.
How often should the breathing tube be replaced?
3M recommends inspecting the tube before each use of the PAPR respirator. Immediate replacement is required if cracks, permanent kinks, discoloration, or loss of flexibility are detected. With intensive daily use on job sites or in workshops, annual preventive replacement is advised. Keeping a spare tube in stock helps avoid work interruptions during urgent maintenance situations.
