3M Speedglas Self-Adjusting Breathing Tube for Adflo PAPR, SG-30W

3M Speedglas SG-30W Self-Adjusting Breathing Tube for Adflo PAPR

The 3M Speedglas SG-30W self-adjusting breathing tube is the standard replacement tube for Adflo TR-300-SG powered air purifying respirators used with Speedglas 9100 FX-Air and 9100-Air welding masks. Made from flexible black polyurethane, it connects the welding mask to the Adflo turbo unit and is NIOSH approved for use in industrial environments.

3M manufacturer code: 7000128097, model: SG-30W, No. 37268

The SG-30W tube is designed to automatically adjust to the welder's working position. Its self-adjusting construction allows it to absorb movements without creating tension on the mask or Adflo unit connectors, contributing to comfortable extended wear. This tube is the recommended replacement part for maintaining the integrity of the Adflo respiratory system in standard configurations.

NIOSH approved, it is intended for MIG/TIG welding, grinding, sanding and industrial maintenance environments. The SG-15 protective cover (sold separately) can be used over the SG-30W to extend its service life in intensive welding environments.

Advantages

Comfort and freedom of movement

• Self-adjusting design: the SG-30W tube automatically adapts to user movements, maintaining a reliable connection between the welding mask and the Adflo unit without binding or placing uncomfortable pressure on the wearer's head or neck.

• Polyurethane material: polyurethane provides optimal flexibility while resisting permanent deformation. The tube retains its shape and mechanical properties even after many use and flexing cycles.

• SG-15 cover compatible: in welding environments, the SG-15 protective cover slides over the SG-30W to protect it against molten metal spatter and sparks, significantly extending its service life.

• Secure connectors: the SG-30W tube connectors ensure an airtight connection to the mask-turbo assembly, guaranteeing that filtered air reaches the breathing zone fully without leakage.

Compliance and reliability

The SG-30W tube is NIOSH approved, guaranteeing it has been evaluated and approved for use with 3M Adflo powered air purifying systems under professional exposure conditions.

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 abrasive environments and high temperatures. If your work environment involves frequent contact with hot surfaces or aggressive chemicals, the SG-40W may be more appropriate. Note that if you use the Adflo with the high-efficiency filter and organic vapour cartridge, the SG-50W tube is required.

How do I know when the SG-30W tube needs to be replaced?

Inspect the tube before each use. Signs requiring replacement include: visible cracks or deformations, abnormal stiffness indicating material degradation, loose or damaged connectors, or persistent odour suggesting contamination. In intensive welding environments, weekly inspection is recommended.

Is the SG-15 cover necessary with the SG-30W?

The SG-15 cover is not mandatory but is strongly recommended in environments generating molten metal spatter, sparks or splashes. It considerably extends the service life of the SG-30W tube and represents a cost-effective preventive investment compared to frequent tube replacement.

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 a faceshield IR3.0 polycarbonate (YV96R3) for face protection.
