Fitting a 5.6 mm hose to a regulator

[gronat]

Hi all,

A complete newby here. This is probably a very stupid question to ask in this high-powered discussion forum, but DIY hasn't been my thing. Your help is greatly appreciated. [This will involve data in metric system.]

I am trying to fit a hose that has an internal diameter of 5.6 mm to my regulator. It turned out that my regulator out of the box has a hose barb too wide to fit the hose, and I am wondering what I should do. I probably need one of those Barbed Hose Connectors. The threaded side of the hose barb is specified as M12 with a pitch of 1.0 (the length of the thread is not given). I think the type labelled 1/4"x12 is the closest to my requirements, but I need someone to double check.

The spec is supposed to be read; Thread size x outside diameter of the wide side. The "Thread size" part really baffles me. It's the wide side that's threaded, but 1/4 inch is very close to 5.6 mm. Am I reading the spec right?

I am open to other ways if you think they are better solutions. Originally, I thought of buying a hose-to-hose coupler, but decided it may leaky; at least if I implement it.



Thank you in advance.

Stick the end of the hose in some hot water to make it soft then ram it on.

Gas hose is normally about 5mm ID. What is the barb diameter? It would be unusual if anything other than (as suggested) a but of brute force is needed. Don't forget to put the clamp on the hose first.

The spec is supposed to be read; Thread size x outside diameter of the wide side.

It's thread size x outside diameter of the barb (= ID of the hose).

A picture saves a thousand words. Id agree onthe hot water!

What is the barb diameter?

8.5mm. I think it's too big.

You can buy different size barbed hose tails with the same thread.

Or warm it up, as hotponyshoes suggests, then expand it using a cone, until it is large enough to get over the barb. If you don't have a suitable cone, a pair of needle-nosed pliers are often suitable.

Being a regulator I would guess the 1/4 refers to quarter bsp.

What type of hose are you using pvc?
If so you want a quick connect push fit thing. "pneumatic fitting"

Is it for a welder?

 

[gronat]

The device I am trying to connect is an air blow gun. No, it's not for a welder, but I am going to use argon for food packing. The shop where I bought it says the blower's 5.6 mm ID hose goes with 1/4" barbed fitting. Now, what I needed all along is a part that "brokers" the metric thread on the regulator and the BSP of the hose.

Thank you.

On all my reducers for argon and co2, the fitting is unscrewed and in its place a quick coupling for pneumatic hoses with a diameter of 8 mm fits perfectly.

If it's for food packaging you might want to use food safe silicone hose.
That should stretch over the barb easily as well.
