[TheForge] Ice rink

[Paul Sperbeck]

If this happens with more than one tank, you need to repair the 
regulator. A damaged surface on the nipple can cause this, Inlet nipples 
are available. If that is not leaking you may have an internal problem. 
DO NOT APPLY TEFLON TAPE OR ANY SEALANT TO THE NIPPLE SURFACE OR THE 
NUT. If you are at all uncomfortable with the pressures involved I 
cannot recommend that you rebuild the regulator yourself.

Repair parts typically will be around $50 wholesale to rebuild the 
regulator, expect to pay between $75 to $100 retail for the parts and 
possibly another $75 to do the rebuild.

It may be cheaper just to replace the regulator. You might be able to 
purchase the regulator and re-use your flow meter depending on 
configuration.

My favorite regulators are older Airco 2 stage units. They have been 
easy to obtain parts for, and have proved to be very reliable after the 
rebuild. I typically pay about $10 to $25 used at swap meets for 
regulators in need of a rebuild.

Resistance Is Not Futile!
It's voltage divided by current.

I have a recurring problem w my inert gas regulators leaking small amts of gas where reg connects to tank. Not a danger for me as leaks r small & shop is large @ drafty. But in a close/tight space would/could be dangerous. We all think abt fuel gas & O2 leaks as dangerous (& they r) but other gasses displace O2.  Just as hazardous 2 u r health.
