The gases that we package and distribute include oxygen, nitrogen, hydrogen, argon, helium, acetylene, carbon dioxide, nitrous oxide, specialty gases and propane. Specialty gases include rare gases, high-purity gases and blended, multi-component gas mixtures. While primarily a packager and distributor of gases, we also manufacture a portion of our acetylene requirements at our facilities in West Mifflin, Pennsylvania and Eddystone, Pennsylvania. In fiscal 2006, acetylene accounted for approximately 3% of net sales. Most packaged gas customers also rent cylinders from us which revenue is included in packaged gases.
Complimentary to the distribution of gases, we sell hard goods or welding equipment and supplies which includes welding machines, wire, fluxes and electrodes and a wide variety of supporting equipment.
We sell propane to the residential, commercial and industrial markets. Typical residential and commercial uses include conventional space heating, water heating and cooking. Typical industrial uses include engine fuel for forklifts and other vehicles, metal cutting, brazing and heat treating. The distribution of propane is seasonal in nature and sensitive to variations in weather, with consumption as a heating fuel peaking sharply in winter months.
The following table sets forth the percentage of our net sales for the fiscal years ended June 30, 2004, 2005 and 2006 for each of the following products and services:
