3M Speedglas Heavy-Duty Breathing Tube for Adflo PAPR, SG-40W

3M Speedglas SG-40W Heavy-Duty Breathing Tube for Adflo PAPR

The 3M Speedglas SG-40W heavy-duty breathing tube is made from neoprene for welders working in particularly demanding environments. Unlike the polyurethane SG-30W, the SG-40W offers superior resistance to heat, chemicals and abrasive surfaces, while providing a reliable connection between the Speedglas welding mask and the Adflo turbo unit.

3M manufacturer code: 7000039458, model: SG-40W

The neoprene SG-40W tube is suited to intensive welding applications where the tube is regularly exposed to molten metal spatter, hot surfaces or aggressive chemicals. Its robust construction extends service life under severe exposure conditions compared to the standard polyurethane model.

Compatible with Speedglas Adflo masks, it is recommended for professionals whose work environment involves high thermal or chemical hazards. Note that if you use the Adflo with the high-efficiency filter and organic vapour cartridge, the SG-50W is required instead.

Advantages

Superior resistance in demanding environments

• Neoprene construction: neoprene offers significantly greater thermal and chemical resistance than the polyurethane of the standard model. It is suited to environments where the tube is exposed to high temperatures, abrasive spatter or chemicals.

• Increased durability: the robustness of neoprene extends the tube's service life under the most severe welding conditions, reducing replacement frequency and maintenance costs.

• Reliable connection: the SG-40W connectors provide an airtight and secure link between the Speedglas mask and the Adflo unit, even during repetitive movements or in constrained postures.

• Adflo system compatible: the SG-40W integrates directly into the 3M Speedglas Adflo system without adaptation, facilitating replacement of the standard tube when working conditions require it.

Compliance and compatibility

The SG-40W tube is designed for use with 3M Speedglas Adflo systems. It complies with the compatibility requirements of the Adflo powered air purifying system for industrial welding applications.

FAQ - Frequently Asked Questions

What is the difference between the SG-30W and the SG-40W?

The SG-30W is made from polyurethane and is self-adjusting: it adapts to user movements. The SG-40W is made from neoprene and offers superior resistance to heat and chemicals. Choose the SG-40W if your work environment regularly exposes the tube to high temperatures, abrasive spatter or aggressive chemicals.

When should the SG-50W be used instead of the SG-40W?

The SG-50W is mandatory when using the Adflo respirator with the high-efficiency filter combined with an organic vapour and acid gas cartridge (OV-AG). In all other standard configurations, the SG-40W or SG-30W are appropriate depending on your work environment.

Does the SG-40W require an SG-15 protective cover?

The SG-15 protective cover can be used with the SG-40W for additional protection against welding spatter. Although neoprene is already more resistant than polyurethane, the SG-15 cover further extends the tube's service life in environments with heavy spatter.

Complementary Suggestions

Complete your welding equipment with gloves Endura goatskin and Kevlar (G625) for MIG/TIG welding, mittens 11-in leather (G602), earmuffs H10P3E 27 dB cap-mount (OPH10P3E), eyewear OX safety glasses (YA12166) and a headgear 3M for CSA hard hats (YPH24).

To protect and transport your Adflo system, add an cover SG-15 (RSG-15) against welding spatter, a bag SG-90 (RSG-90) for safe transport, and gloves split leather (G308) with safety cuffs for light welding.
