## Questions & Answers

**Q: What size of the steel tube that goes into the connection??**
A: The plated tube is .548" outside diameter 
1.750" between the body and the nut.
In metric 14 mm outside Diameter
The plating may have added several thousands to the pre plating diameter.
I cannot see enough of the threading into the body to tell the thread size, but suspect it is metric probably made in China.
Hope that helps Richard

**Q: Instructions that came with the unit says to make sure the "sealing washer is in place on the yoke inlet."  no washer shipped - is it required?**
A: no washer needed it should be the brass nipple on the regulator connected to the brass cylinder valve

**Q: What size is the hose barb on this reg?**
A: It looks to be about a 3/16" Hose barb.

**Q: Does this fit the disposable o2 tanks sold in places like home depot?  thanks...**
A: It uses CGA540 Connector Type. Don't know if those are sold at HD. I bet not.

### ⭐⭐ Review
*by P***T on 3 May 2023*

There is indeed no gasket included with this regulator. I ordered two and both came without a gasket. I also contacted Medline and they said they come without a gasket. It’s unusable unless a gasket can be purchased elsewhere. So far I have not been able to find one that works. The air simply escapes from the threaded part. Other than that quality seems good but unusable in its present form.
