• Piston & Rider Rings

Application-engineered Piston & Rider rings are available for all operating conditions. They provide excellent sealing capabilities & piston support, preventing piston-to-cylinder contact.

 

 

 

 

We fabricate these rings in a variety of styles ranging from a conventional segmental straight, angle cut, step cut design, to more complex configurations like two & three piece segmental, grooved outer face and beveled edges & including the twin ring design.

 

 

 

Piston & Rider rings are manufactured from various composites of PTFE - Glass fiber, Glass graphite, Glass molybdenum-disulphide, Carbon, Graphite, Ceramic, Bronze & Bronze molybdenum-disulphide for applications in low to high pressure & continuous duty air and gas compressors. These rings are available for cylinder sizes 2" to 32".

 

 

 

• Piston Rod Packing

Over two decades of experience & expertise gives us the ability to manufacture compressor-packing components that satisfies specific reciprocating compressor requirements. Demanding quality standards are what makes our conventional radial-tangent packing rings so reliable — and long lasting. These precision, light-tight seals compensate for wear, movement of the rod, and changes in pressure, service or temperatures.

 

 

 

Piston Rod Packing are offered in an almost unlimited variety of materials - and designs for unidirectional & bi-directional sealing; low-pressure vent sealing & gas purge sealing combined with exacting manufacturing & quality standards. Also available are high pressure rings with metallic backup. Additional types of ring configurations for specific applications can also be recommended.

Piston rod packing is available for rod sizes 1" to 12".

 

 

 

• Oil Wiper Rings

Oil Wiper rings are manufactured to effectively provide positive containment of lubricants within the crankcase. In addition to wiping rings, which essentially scrape liquid from the rod, most wiper packing also contain sealing rings to block gas pulsations or flow through the packing.






Oil Wiper Rings are manufactured in several designs, including tangent cut unidirectional, tangent cut bi-directional and triple circle design. They are manufactured from Cast Iron, Bronze, Aluminum Alloy, Carbon, Stainless Steel & PTFE ®. Oil Wiper Rings are available for rod sizes 1 1/2" to 8"

• Expander Rings

An expander when added to a plastic ring will provide it with more initial tension and improve its sealing characteristics. Ring tension is most often obtained from the ring itself. However, in some instances - if the cross section is light, or the ring material is soft, or if the ring is segmental - a separate spring may be needed to supply radial force to the ring. The basic ring plus the expander is particularly suitable for low pressure and applications where expander-to-piston contact is to be avoided. The same ring concept can be furnished in two segments version or three segments version.

• Valve Components

With the wide variety of valve designs in use today, it is essential that quality components be utilized to provide maximum service life.
