The breaker ring is used to reduce and control the pressure that the sealing rings see in higher pressure applications. Reduced pressure leads to longer life and more efficient sealing of the active packing rings. The breaker ring has clearance designed into it to accomplish this function. It also throttles the pressure on the suction stroke.

The Type 211 pair of packing rings consist of two tangent to the step rings pinned together to overlap at the step. This design has traditionally been used to seal low pressure or vacuum applications. The pair of tangent rings allows the 211 style to seal in both directions. Because of the large sealing surface, more frictional heat is generated and therefore greater wear to the piston rod and the seal itself. The 211 design does not allow gas to pass back through the packing case when pressure drops from discharge to suction in the cylinder, therefore its application should be limited to low pressures such as after the vent connection, vacuum service or in partition packings.

The AAVOLYN Type 254 is designed to be installed in the first sealing groove toward the cylinder. It's internal grooving arrangement is used to trap solids in the gas, preventing them from filling the packing groove and restricting the performance of the packing rings. This design has been used in many applications where packing rings have not been able to function effectively due to the build up of solids in the groove from the cylinder. By minimizing the amount of solids allowed to enter the sealing ring area, the life of the packing assembly is increased.
Single acting radial-tangent pairs consist of a radial load ring and a tangent sealing ring. The pair act together as a seal in one direction. The Type 210 are installed in combinations depending on the discharge pressure. They keep the gas from leaking from the cylinder to atmosphere. The radial ring is pinned to the tangent or sealing ring to prevent gas from leaking at the tangent joint. The pair of rings seal at the bore and against the back side. To obtain an effective seal the finish and parallelism of the faces are critical. Proper side clearance is required for the packing to function at operating temperatures and not be restricted in the packing case groove.

Where discharge temperatures are a problem over 500 PSI, in non-lube and 2500 PSI, in lubricated service, the AAVOLYN Type 260/230 PBU pressure balanced design with back up ring is recommended to optimize ring life.

This AAVOLYN Type 313 oil wiper ring is used in reciprocating compressors to prevent oil
from the crankcase traveling along the piston rod and into the pressure packing. It consists
of an individual oil seal manufactured tangent to the rod with no clearance at the bore. Each
ring is an independent seal with a deep wiping edge and wide oil groove at the I.D. The oil
groove acts as a second wiping edge and uses drilled holes to allow the wiped oil to drain
away from the rod. AAVOLYN uses a tapered wiping edge on the face of the ring to more
effectively strip the oil coating from the piston rod.

The Type 320 radial oil scraper ring is designed to be used pinned in sets as a wiper

provide maximum oil removal.
The AAVOLYN 320 design includes the unique tapered wiping edge, deep oil grove in the
bore and large oil ports to allow rapid removal of oil wiped from the rod. It is utilized in many
gas and process compressors depending on the design of the compressor manufacturer.

The pressure breaker is used to stabilize the packing in the compressor. It is bored slightly
over the rod diameter to allow a controlled leakage at the bore of the ring. This breaking down
of the pressure in the first packing cup allows a slow buildup and drop off of pressure on each
stroke.

The AVA-PBU pressure balanced unitized design is the latest concept in shaft seals. The
AVA-PBU was developed to extend packing life in conventional applications. However, it has
found use in all services from non-lube air to 50,000 PSI compressors handling polyethylene.
Each ring operates on the principle of balancing the pressures around the seal to minimize
the downward force of the piston rod. Frictional forces are reduced considerably. In
applications where filled PTFE materials are utilized, there is less chance that the PV
limit (temperature/pressure limit) of the PTFE will be exceeded because of reduced
frictional heat.

This design consists of one PTFE radial ring pinned to one PTFE tangent ring along with
an iron or bronze backup ring. The PTFE radial ring faces the pressure and is installed
as shown.
This style of packing ring is used in higher pressure applications where the seal ring is made
from a thermoplastic material, including filled PTFE. At these pressure ranges a backup
ring is required to support the sealing ring at the bore to prevent extrusion. The packing
groove is not wide enough to utilize the Type 210 pair of rings with a backup. Therefore one
ring replaces the normal pair and serves as a radial and tangent combined.

This design, used in a wiper packing assembly, consists of a three ring set; a male radial
ring, female radial ring and tangent cut ring as shown above. The wedge packing set is
installed facing the cylinder with the female radial ring facing the pressure. The purpose of the
wedge packing is to prevent the gas from getting into the crankcase.
It can also be utilized in very low pressure applications where the radial tangent pair does not
exert sufficient force on the piston rod to create a seal. The male/female combination load
ring creates sufficient force on the rod with the expansion of the PTFE material due to a
temperature increase at operating pressure. This pressure allows the ring to seal where the
normal ...

The Type 495 wiper assembly consists of two (2) AAVOLYN Type 314 wiper rings and (1) AAVOLYN Type 313 wiper ring. The AAVOLYN standard wiper Type 313 utilizes a true tapered stripping edge as part of the normal wiper ring configuration. This tapered edge, comparable to that used in oil rings for power cylinders, strips the oil effectively off the rod surface. This feature combined with the additional wiping problems in the field for gas gathering applications. The rings fit in a standard wiper groove and do not require modification of the wiper gland.
