Important - These hoses have small American torch connections type "A"
the inlet end is suitable for UK  FBA / regulator outlet connections being G3/8.   
European or French inlet connections also available - G1/4 / G3/8 / M12 / M16 on request.

High quality micro bore hose suitable for all oxy / fuel applications that require a small or micro flow.
These micro bore "welding hoses" have been manufactured in the UK and produced with due regard for BS EN 3821 even though these hoses fall outside the scope of the standard due to their small size.

These hoses have been manufactured in blue for use with oxygen and orange for use with fuel gases.  Generally red acetylene hose cannot be used with LP gases whereas orange LP gas hose may be used safely with acetylene and this was the reason why Noz-Alls decided to manufacture in Blue & Orange.

The micro bore hoses are super flexible which makes them ideal for use with the traditional light "aircraft style" miniature blowpipes / torches from America typically from companies like Harris, Smith and Uniweld. 

These hoses are supplied with American "A" torch fittings (3/8 x 24 tpi nuts) with G3/8 regulator connections, left hand for fuel gas and right hand for oxygen. For clarity - standard industrial regulators mostly fitted with 3/8 BSP but the small portable / DIY kits may be different. (G1/4).  See options when selcting your choice.  Please contact
Noz-Alls if you require an alternative option not listed.

Micro Bore Hose Length -  Micro bore hoses are typically used with the smallest of nozzle sizes on small torches, therefore please note the following which is very important for your safety and that of your equipment.
Lack of purging or incorrect purging is the major cause of flashbacks in gas equipment this is compounded by the use of small nozzles which makes purging more difficult to achieve.
Therefore the use of long lengths of micro bore hose is not recommended for everyday use.
From a safety point of view, where access is required to reach a job and the lifting and positioning of cylinders would present a greater safety risk, then it is best practice to fit long hoses but only on a temporary basis, as the overall risk to safety would be reduced.  The extension hoses should be removed after use and the standard hoses refitted.
When long hoses are fitted remember that the hoses will require purging correctly,  an artisan lead "burning" using the Model "O" blowpipe / torch or the Smith type Little Torch, the nozzle should always be removed from the torch to purge the gases. 
The fuel gas & the oxygen must be purged from each hose prior to lighting up.  Due to the small orifice size in the Model "O" nozzles (even smaller in the Smith Little Torch nozzles) if the nozzle remains in the torch the purging time would be very extended as an example the Model "O" #1 oxy / acetylene nozzle would take 5 minutes of purging per hose to clear 5metres of micro bore hose based on moving 2x volume of hose If you were using standard 6.3mm bore x 5m hose set this would require 18 minutes of purging per hose!
Therefore you may see how important it is to remove the nozzle to purge correctly - with the nozzle removed the hoses may be purged in a matter of a few seconds.

Using an ex-medical / refurbished oxygen generator to supply your oxygen for your micro torch then you may need an alternative connection for the FBA / outlet of the generator.  Alternatives adn mixed hose inlet connections are possible.  Please ask.
