270407 - Miller 100ft SAR Straight Air Hose with Industrial Interchange Fittings

Miller 270407 100ft Straight Air Hose for SAR Systems

The Miller 270407 is a premium-quality straight air hose designed specifically for Supplied Air Respirator (SAR) systems. Engineered by Miller Electric, this 100-foot hose provides the essential link between your breathing air source and the operator's personal protective equipment. With a generous length of 100 feet, it offers exceptional mobility, allowing users to navigate large industrial environments, shipyards, or fabrication shops without the constant need to reposition the air supply unit. The hose is constructed from durable rubber, ensuring it can withstand the rigors of daily industrial use while maintaining flexibility.

Technical specifications are critical when selecting breathing air components. This hose features a 3/8-inch inner diameter (ID), which is optimized to deliver the correct volume of air to the regulator without significant pressure drop over the 100-foot distance. It comes pre-installed with 1/4-inch Industrial Interchange fittings. These fittings are selected to meet specific safety standards; per OSHA 29 CFR 1910.134(i)(8), breathing air fittings must be incompatible with outlets for non-respirable work-site air or other gas systems. This design feature prevents accidental connection to dangerous gases like oxygen or fuel gas, ensuring the safety of the operator.

This hose is specifically designed to pair with the Miller C50 air regulator. When used in a single-hose configuration (25 to 100 feet), the system typically operates within a pressure range of 58 to 61 psi, ensuring a steady flow of Grade D breathing air. Whether you are upgrading your existing safety gear or replacing a worn hose, the Miller 270407 ensures your SAR system operates at peak performance. It is an essential component for maintaining a safe, compliant, and comfortable welding environment.

Key Features:

• Extended Reach: 100-foot length maximizes workspace coverage.
• Safety First: Industrial Interchange fittings help prevent cross-connections.
• Durable Build: Rubber construction resists wear and tear in harsh environments.
