Crown Ring Packing

Why Crown Ring Packing Is Important

Crown packing allows sealing on polish rod and ID of the box without extensive tightening. For years, these crown polishing rings have been used for long stroke pumping unit applications with a high degree of success.

In addition, in highly pressurized oilfield environments, our crown rings tend to last longer and perform better than many of our competitors’ lesser made products. Add to that our great prices and quick turnaround times on all orders, and you can see why choosing Global Elastomeric Products, Inc. for your crown ring packing needs is such a prudent choice.
