Seal your hose properly — sized automatically to match the bore you selected. We’ve added 2 — one for each end of the hose. Adjust if you need more or fewer.
The Master-Clip SPARK is a special hose for welding fumes extraction, made from PVC-coated glass fabric. It is very flexible and light in weight, moderately pressure resistant, with a dark grey wall.
Constructed as a spiral hose with clamping profile with a glass fibre fabric wall, it operates from -20 °C to +90 °C (peaks to 110 °C). Available in bore sizes from 50–900 mm, in 10 m, 15 m, 20 m, 25 m lengths.
Wall material: flame retardant.
Note: ATEX / explosion-zone suitability must always be assessed for your specific installation by the operator.
