Compression Fitting

[Levaughn]

Could someone tell me the size of this compression fitting and where I can get another one? The micrometer says the hose size is -4.63mm. Thanks in advance.

4.63mm is probably 3/16" tubing. But zero your caliper properly and recheck the measurement.

 

[Levaughn]

Ok. Thanks.

I zeroed the micrometer and it still said the same thing. I did a computer search a found the replace hose which says the size is 4mm.

What's that off of?

Worst case just match the thread and replace the run with copper.

The tube is the line for the Argon hook up on a Bokrand gmbh pocket mig, 110v. I have two of them. One doesn't have the end to go to the tank like the one in the picture.

Please...that is not a micrometer, it is a caliper.

4mm compression fittings are available on ebay
what does it thread in to?

It threads into a larger fitting which goes to the Argon.

I cleaned up the fitting and it has the name "Sistem" on it. I have to get a 4mm fitting. Thanks again to all.

It's unusual for tubing to swell that much. Best to order new tubing because you'll have a heck of a time getting that old tubing into a new fitting.

 

[Levaughn]

Will do. Thanks.

Are there any markings on the hose? That is not a compression fitting either - that is a "push-to-connect" fitting.

All I see is "Sistem" stamped on the connector. Someone cut the connector off the end of that small white hose that goes to the tank. I took the trigger apart and the same fitting is on the end of the trigger.
