Over 65 years ago, Hasco Manufacturing Company ("Hasco") began manufacturing a select line of specialized oil field equipment.
Hasco's goal was not to make everything they could, but to specialize in a few products and concentrate on making them better than anyone else.
Hasco's underlying theme simply put is "Treat our customers as we would like to be treated". Some have called this the Golden Rule of Marketing, Hasco calls this just good business.
Hasco was the first company to make most of the standard sizes of Polished Rod Liners in use today. Hasco was the first to implement a color code system, which distinguishes the different sizes and types of Polished Rods and Polished Rod Liners.
Hasco has had the only innovation in Polished Rods and Polished Rod Liners in the last 50 years. These innovations are now patented as the "Twin Pin"?Polished Rod and the "Hasco Environmental Safety Seal Liner"?
Hasco does more than offer just a product. We offer the customer a solution.
