The Miller SAR 25 foot straight air hose is designed for air respiratory systems that utilize 1/4 inch interchange fittings. This hose comes with a 3/8 inch ID (interior diameter) and is designed to fit Miller's C50 air regulator.

This hose is not compatible with Miller's portable BreatheAir Filtration systems which utilize a 1/2 inch interchange fitting. These systems would require the 276005 or 276006 straight hoses.
