Welding and Scarfng Hose
Grade T Performance
Series 7228T (Red – Fuel Gas Line)
Series 7229T (Green – Oxygen Line)
Series 7228T/7229T is a heavy duty welding and scarfng hose featuring a fame
and oil resistant tube and cover. Red Series 7228T is compatible with commonly
used fuel gases, including acetylene, hydrogen, natural gas, propane and
propylene. Green Series 7229T is only for oxygen service. Te non-blooming tube
minimizes the migration of combustible waxes or plasticizers to the surface of
the rubber. Single line welding and scarfng hose is available in long continuous
lengths, providing maximum versatility and ease of handling in a variety of
applications where the fuel gas and oxygen sources are separated. Te robust
construction incorporates premium rubber compounds to provide Grade T
performance, and the braided reinforcement provides working pressures greater
than conventional welding hose, maximum kink resistance and secure coupling
retention. Te thick cover is resistant to abrasion, cuts, fame, gouges, mild
chemicals, oil and ozone.
