Recent developments in air and gas compressors have allowed equipment to work at higher pressures and greater efficiencies, even as the overall device size has decreased to meet specific application requirements. All these developments have worked together to place unprecedented demands on equipment design, including sealing rings.

Grover product specialists are knowledgeable in the latest technologies, and can suggest the best solution for your OEM application. Manufacturers of Reciprocating Compressors, Climate Control Systems, Vacuum Pumps, Air Treatment, Gas Processing, Natural Gas Processing and Power Generation -- all have come to count on Grover products.

Although there are several types of rings used in air compressors and gas compressors, Grover's unique taper face Permaseal® design is particularly well-suited in compressor applications. It provides high unit loading against the cylinder wall which ensures quick ring sealing and superior oil control.

The combination of the Permaseal®joint design and a taper face OD feature significantly reduces oil bypass in reciprocating air compressors. Precision machining of the taper face Permaseal provides consistent performance. This design offers an overall cleaner and more efficient system.

Some of the specific benefits of Grover's taper face design are:

• Manufactured of piston ring grade cast iron and other materials for performance designed for your specific application.
• Reduces oil bypass down to 2 particles per million.
• Precision machined for consistent performance.
• Superior CNG sealing capabilities.

In addition to the Permaseal Taper Face, OEM manufacturers of air and gas compressors can call Grover for Step Seal, Angle Step Cut, Butt Taper Face and Angle Cut Sealing Rings. Rings can be supplied from 1/2 in (12.7mm) in diameter to 90 in (2286mm), in a variety of alloys and coatings.
