OVERVIEW

Reliable Breathing Air Delivery for Industrial Safety

The Miller 270405 SAR Straight Air Hose is a critical component designed for Supplied Air Respirator (SAR) systems, specifically engineered to connect Miller's C50 air regulator to a Grade D breathing air source. In industrial environments where air quality is compromised by fumes, particulates, or gases, maintaining a reliable supply of clean, breathable air is paramount for operator safety and compliance. This 25-foot hose provides the necessary link to ensure that welders and industrial workers remain protected while performing their duties.

Constructed with durability in mind, this straight air hose features a 3/8-inch inside diameter (ID), which is optimized to maintain the correct pressure and flow rate required by the C50 regulator system. The hose is terminated with 1/4-inch Industrial Interchange fittings. It is important for safety managers and operators to verify that their facility's breathing air outlets are compatible with Industrial Interchange fittings. Per OSHA regulations, breathing air fittings must be incompatible with outlets for non-respirable work-site air or other gas systems to prevent accidental cross-connection. If your site uses Industrial Interchange for other gases, alternative Schrader-style fittings may be required (sold separately).

The 25-foot length offers a significant range of motion, allowing operators to move freely around large workpieces or fixtures without being tethered too closely to the air manifold. Unlike coiled hoses, which can sometimes create tension or pull on the operator's belt assembly, this straight hose lays flat and allows for easier management over longer distances. Whether used in heavy fabrication, shipbuilding, or tank manufacturing, the Miller 270405 hose ensures that safety does not come at the expense of productivity.

FAQ

The Miller 270405 air hose is 25 feet long.

This hose comes with 1/4-inch Industrial Interchange fittings.

The hose has a 3/8-inch inside diameter.

Yes, this hose is specifically designed to fit the Miller C50 air regulator used in SAR systems.

No, this hose is intended strictly for Grade D breathing air applications within a SAR system. Never use it for fuel gases or shielding gases.

This is a straight air hose.

It uses Industrial Interchange fittings. OSHA requires breathing air fittings to be incompatible with other site gas outlets. If your site uses Industrial Interchange for other gases, you may need the Schrader version instead.
