Autogenous twin hose, O2-C2H2, Ø 13.3 x 6.3, 30 m, connections - Riegler 156073

Autogenous twin hose for oxygen-acetylene, blue-red, rubber, hose-Ø 13.3 x 6.3, roll of 30 m, with connections The autogenous twin hoses in accordance with DIN EN ISO 5172 are pre-assembled and ready to use, each with two hoses nozzles for a G 1/4-connection for oxygen and a G 3/8 LH connection for acetylene. They are clearly superior in terms of quality, as the two hose lines are not manufactured individually and then glued together, but are extruded together in a single operation. They are therefore permanently welded together without the risk of them coming apart over time.

About Oxyacetylene hoses

Welding hoses carry oxygen and fuel gas from the pressure regulator to the torch. The group holds ready-made twin hoses and single hose by the roll, each with a hose size of 13.3 x 6.3 mm and a rating of 20 bar.

What matters when choosing

• Gas and colour: blue is oxygen, red is acetylene. On the twin hose both lines are permanently joined and cannot be routed separately.
• Connections: thread 1 is G 1/4 female for oxygen, thread 2 is G 3/8 LH female for acetylene. The left-hand thread on the fuel gas side prevents the lines being swapped.
• Roll length: the ready-made twin hoses run from 4 m to 40 m, the single hose comes as a 50 m roll for cutting to length.
• Assembled or by the roll: made-up hoses arrive with hose tails at both ends, roll goods need tails and clamps from the accessories.
• Max. operating pressure 20 bar applies to the whole group and sits above the usual working pressures at the regulator.

Typical applications

• Oxy-fuel welding with oxygen and acetylene
• Flame cutting of sheet and sections
• Brazing in pipework and plant construction
• Flame straightening and preheating in metal workshops
• Replacing worn hose lines on existing torch sets

The made-up twin hoses are built to DIN EN ISO 5172, the single acetylene hose to DIN EN ISO 3821:2010 with an abrasion-resistant EPDM/SBR cover. Countries of origin are Thailand and the Czech Republic.
