Quality hoses from Noz-Alls. This particular hose comes in the following setup;
10m Acetylene Hose with a 10mm Bore. 
3/8 BSP Nut for connection to a regulator or outlet. 
3/8 BSP HCV for connection to a torch.

Acetylene hose for cutting & heating applications,
10mm bore hose is generally a little too heavy for welding applications due to the hose weight.  

These are "standard" quality hose for everyday use - please don't be tempted to purchase cheap hoses as we have tested many and they don't meet the standards (even though they are marked that they do). 
we also supply thicker and heavier hoses - also made to the same standards - but which have superior characteristics and last longer in arduous environments.

The oxy / fuel hoses Noz-Alls supply do of course meet all the necessary standards, the hose is manufactured to BS EN ISO 3821, all the hose fittings are produced to our own engineering drawings, the connection nuts are manufactured to BS EN ISO 560 with the nipples being produced to BS EN ISO 1256 and finally the HCV (hose check valves) are manufactured to BS EN ISO 730-2 and we know the HCV function correctly because we 100% test them in house before they are sent to the hose manufacturer for assembly.

You may be confident of good quality and fact that they are safe to use.
