Oil wiper packing is designed to seal the oil from the crankcase. By scraping away the excess oil generated along the piston rod by its back and forwards movements, the oil wiper rings prevent any accidental leakage outside the crankcase of Air and Gas compressor (CNG Compressor).

• Oil Scrapper Rings are available in different MOC, i.e. Individual graded cast iron, Bronze, glass filled PTFE, with perfect roundness, inner grooved & drilled to wipe oil from piston rod & with S.S. garter spring with proper tension.

Basic Wiper Ring Designs:

• tangent cut unidirectional
• tangent cut bidirectional
• radial cut wiper rings

Highly reliable oil scraper rings :

• These components are essential to compressor efficiency, especially in the case of oil-free compressors where there should be absolutely no trace of oil.
• The oil wiper rings prevent any oil contaminating the cylinder.
• Reliable control of crankcase oil leaks is economically vital in view of the increasing price of oil. Care for the environment is also an important consideration.

Basic Packing Ring Designs:

• Single acting seal rings/pairs
• Double acting seal rings/pairs
• Backup rings
• Pressure breakers
• Pressure breaker with relief slots

Packing and Wiper Ring Materials:

• Carbon Filled PTFE
• PTFE
• Thermoplastics
• Bronze
• Cast iron

From last many years, we are engaged in the industry as one manufacturers and suppliers of Hastings Piston Rings. Our exceptional array is precisely engineered in synchronization with the predefined international standards and norms. Considered as the individual cast and close material control, the range of rings is used in different industrial applications. We offer our Hastings Piston Rings at highly economical prices with prompt deliveries.

• Resistant to wear
• Precise dimensions
• Low maintenance cost

The function ofPISTON RINGS, mounted on the pistons of lubricated or non-lube (oil free) compressors, are designed to ensure that the gas is compressed and to provide a seal between the piston and the cylinder.The function ofRIDER RINGS, used mainly in oil free or mini-lube compressors, is to support or guide the piston and rod assembly and prevent contact between the piston and the cylinder (risk of seizure).

• One-piece or segmental straight
• Angle cut
• Step cut
• Twin Ring
• Double Twin Ring
• Two Segment
• Pressure balanced

AEW also custom designs rings and has developed specific combinations for particularly problematic and demanding applications. This has also included numerous successful conversions from lubricated to non-lubricated operation. Pressure balanced rings are available, when deemed appropriate for high pressure applications and piston/rider ring combinations are also available for more specific applications.
