OVERVIEW

Heavy-Duty Protection for PAPR Systems

The 3M™ Speedglas™ Breathing Tube Cover SG-15 is a critical accessory designed to safeguard the integrity of breathing tubes used with 3M™ Adflo™ Powered Air Purifying Respirators (PAPR). Identified by part number 70-0716-0797-5, this cover is engineered specifically for high-temperature environments where standard rubber or plastic tubes might be susceptible to damage from radiant heat, sparks, or molten spatter.

Constructed from durable, heat-resistant materials, the SG-15 acts as a sacrificial barrier. By absorbing the wear and tear of the industrial welding environment, it prevents premature failure of the actual breathing tube (such as models SG-30, SG-40, and SG-50). This not only ensures the safety of the operator by maintaining the integrity of the airflow path but also represents a cost-effective maintenance strategy by prolonging the replacement interval of the more expensive breathing tube assembly.

The cover is designed to fit securely over the tube without compromising flexibility. It allows the welder to move freely, ensuring that the PAPR system remains comfortable and unobtrusive during long shifts. Regular inspection of the breathing tube is recommended, and the removable nature of the SG-15 facilitates easy access for these safety checks.

FAQ

The SG-15 cover is designed to fit 3M™ Speedglas™ breathing tubes, specifically models SG-30, SG-40, and SG-50, commonly used with the Adflo™ PAPR system.

A breathing tube cover protects the rubber or plastic tube from burns, punctures, and abrasion caused by sparks, spatter, and sharp edges, significantly extending the life of the tube.

Yes, the SG-15 is the 'High Temperature' version, specifically engineered to withstand the heat and spatter associated with heavy-duty welding processes.

The cover slides over the breathing tube before the tube is connected to the helmet or blower unit. It is designed to stay in place during use.

While it can be wiped down, it is primarily a sacrificial protective layer. If it becomes heavily soiled with oils or damaged by burns, it should be replaced to ensure continued protection.

No, the SG-15 is designed to be flexible so it moves with you and doesn't restrict your head movement while welding.

Yes, this is the genuine 3M Speedglas SG-15 Breathing Tube Cover, part number 70-0716-0797-5.

It is designed for the QRS (Quick Release Swivel) style tubes. If you have a very old legacy system, check your manual, but it fits most modern Adflo tubes.
