Piston Ring

We manufacture and keep sufficient stock of different varieties of Piston and Rider Rings upto 56” diameter of special POLYMER Alloys, commonly used for Sealing and support of Pistons and Rod Packings of Non-Lubricated Compressors upto 5000 lb/sq.inch.

Piston Rings and Rider Rings can be supplied on the basis of Part Numbers of World renowned Brands Compressors or according to dimensional and service requirements. Piston Rings and Rider Rings manufactured by us are perfect circles, which exert unit outward pressure .

In the Cylinder Wall that ensures perfect sealing. They also fit perfectly in the grooves of Piston. These rings have natural lubricity and low frictional characteristics and provide protection during start-up, high pressure and wear and tear resistance when oil film develop in the walls of the Cylinder. These retain the same characteristics even if oil films do not develop in the walls of the Cylinder. The mention below two functions of Piston Sealing Rings.

(a) To prevent escape of Gas from the Piston.
(b) To prevent Heat Transfer from Piston to outside through the Cylinder wall.

CAST IRON: We manufacture Piston Rings and Oil Rings from Graded Cast Iron. These are duly Heat Tensioned so that they can work properly in different temperatures.

Packing Ring

BRONZE: We manufacture Bronze Piston Rings of various Grades according to specifications. The common specifications are Chilled Castings of Cu:Sn:Pb=80:10:10. Bronze Rings manufactured by us work properly in high temperatures, pressure and low lubrication and have resistance to wear and tear.

Whatever the corrosive Gases handled by your Compressors, we have the right combinations of properly utilized PTFE materials that have packing, sealing and bearing properties in different operational characteristics of Reciprocating Compressors. To obtain Filled PTFE materials Virgin PTFE materials are homogenous blended with selected proportions of Carbon, Graphite, Glass Fibre, Bronze and Moly, PEEK, Micarta and Phenol are also used to manufacture these Rings. We manufacture Piston Rings, Bearing Rings etc of any design, including One Piece, Segmental, Composite and Twin Ring as per customers’ specific requirements.
