ABSTRACT:
A valve for an inflatable body has the inside of a valve member within the body having opposed wall portions normally superposed on one another and movable upon forcible separation. The inside of the opposed wall portions are coated with a viscid, non-hardening material preferably a polyglycol which minimizes leakage of helium and a like gas through the valve when the body is inflated.
