We are sure you are aware of other companies that market hydrocarbons that contain the “rotten egg or sulfur odor”. This smell comes from the sulfur in a blend that is unrefined or from an additive called ‘mercaptin’ which some companies add for the odor itself. Mercaptin is made from sulfur. When sulfur is introduced to moisture, it becomes an sulfuric acid.

Enviro-Safe™ R134a Replacement Refrigerant is highly refined! Enviro-Safe does not contain the “rotten egg, sulfur, propane” odor.

The products we market have been perfected over the years, and are pharmaceutical
 grade, highly refined and computer blended to within 1/4 of 1% by a major American petrochemical supplier. This means our products are consistent each and every time our customers use them!
