Construction and selection
This series has separate oxygen and acetylene channels. The pressure summary identifies each channel individually; keep the hose markings and end connections matched to the intended gas. Confirm the applicable welding-gas standard and assembly requirements for the destination market.
The listed models cover 1/5" – 3/8" (5 – 10 mm). Select an actual row in the specification table; the range does not mean every intermediate size is stocked. Sizes outside the table require a separate quotation and specification.
Operating specifications
The working pressures listed for this series are O₂: 20 bar / C₂H₂: 10 bar. Use the value for the selected model and grade, not the highest value across the series. Working pressure and burst pressure are separate limits; a burst-test value is not an operating pressure. Where BP is listed, use its pairing with WP in the same row; do not assume one burst ratio for every model.
The published range for the standard construction is -10°C – +60°C. Confirm continuous operation with the actual fluid, pressure and duty cycle. No separate short-term peak rating is documented for this series; higher-temperature operation requires a separately confirmed specification.
Supply format and options
The model table lists coil lengths of 30, 50 m. Check the length against the chosen model. The hose ratings describe the hose itself. Cut lengths, connectors and finished assemblies must be agreed in the quotation, including end fittings and any assembly testing. A coil length does not specify a finished assembly length or rating.
The listed model and material define the standard specification shown here. Treat requests for other compounds, colors, reinforcement, sizes or compliance documents as separate options, subject to written confirmation. A generic material name or standard reference is not a certificate for every model.
MOQ: Confirm by model (m). Bulk hose: m; Finished assemblies: pieces — Confirm by model.

Frequently Asked Questions
What construction does this series use?
This series has separate oxygen and acetylene channels. The pressure summary identifies each channel individually; keep the hose markings and end connections matched to the intended gas. Confirm the applicable welding-gas standard and assembly requirements for the destination market.
Which sizes belong to the listed series?
The listed models cover 1/5" – 3/8" (5 – 10 mm). Select an actual row in the specification table; the range does not mean every intermediate size is stocked. Sizes outside the table require a separate quotation and specification.
What working pressure should I use?
The working pressures listed for this series are O₂: 20 bar / C₂H₂: 10 bar. Use the value for the selected model and grade, not the highest value across the series. Working pressure and burst pressure are separate limits; a burst-test value is not an operating pressure. Where BP is listed, use its pairing with WP in the same row; do not assume one burst ratio for every model.
What is the temperature range, including short-term peaks?
The published range for the standard construction is -10°C – +60°C. Confirm continuous operation with the actual fluid, pressure and duty cycle. No separate short-term peak rating is documented for this series; higher-temperature operation requires a separately confirmed specification.
Is this bulk hose or a finished assembly?
The model table lists coil lengths of 30, 50 m. Check the length against the chosen model. The hose ratings describe the hose itself. Cut lengths, connectors and finished assemblies must be agreed in the quotation, including end fittings and any assembly testing. A coil length does not specify a finished assembly length or rating.
Are other materials, sizes or certified versions standard?
The listed model and material define the standard specification shown here. Treat requests for other compounds, colors, reinforcement, sizes or compliance documents as separate options, subject to written confirmation. A generic material name or standard reference is not a certificate for every model.
What information is needed for a quotation and minimum order?
MOQ: Confirm by model (m). Bulk hose: m; Finished assemblies: pieces — Confirm by model. Send the model, size, material, intended medium, operating conditions and quantity. Specify bulk hose in metres and assemblies or fittings in pieces. Confirm minimum quantity, packaging and lead time in the quotation for the chosen configuration; optional versions may have different order requirements.
