Grade R Single Line Welding Hose
ARPM IP-7
Series 7120 (Red – Acetylene Only)
Series 7121 and Series 7031R
(Green – Oxygen Line)
Series 7120/7121 is a single line acetylene/oxygen welding hose. Red Series 7120
is only for fuel service and is compatible only with acetylene. Green Series 7121
is only for oxygen service. Te non-blooming tube minimizes the migration of
combustible waxes or plasticizers to the surface of the rubber, and the multiple
plies of textile reinforcement provide fexibility. Single line welding hose is
available in long continuous lengths, providing maximum versatility and ease of
handling in a variety of applications where only single line hose is needed or where
the fuel gas and oxygen sources are separated, and twin line hose is not practical.
Te cover is resistant to abrasion, heat, mild chemicals and ozone.
NOTES:
• For 3/4" Grade R oxygen hose, refer to Series 7031R.
• Grade R is also suitable for use with inert gas.
