Components

Female ring is assembled opposite to the pressure flow and therefore, besides supporting the V-Rings, it has to be highly resistant to extrusion. As the Female ring is particularly subject to wear, it is supplied with an anti-extrusion

 ring in special heavy-duty applications.   

Common Materials

Metallic: 

Stainless steels, Alloy steels, Cast iron, Bronze alloys   

Elastomers:

Fabric/Rubber

Plastics:

PEEK, PPS, UHMW, Nylon , PTFE  

Also Known As: 

Gland Ring -  Top Adapters  -  Support ring

V-Rings are the sealing elements in all V-sets. The profile enhances the sealing performance in low and high pressure applications and responds 

automatically to changes in system pressure.  Many different V-Ring profiles and materials are available.  

Common Materials 

Metallic:

NA

Elastomers:

Fabric/Rubber, NBR, HNBR, EPDM, FKM, FFKM, AFLAS   

Plastics: 

PEEK, PPS, UHMW, Nylon , PTFE     

Also Known As:

Intermediate Ring  -  Chevron Ring  -  Packing Ring  -  Vee Ring  - Pressure Ring

Male ring it has no sealing function, it helps to energized the V-Rings.  

Male ring can be supplied with 

groove and or axial notches 

ensure equal pressure 

to the sealing edges of the 

V-Ring.

Common Materials

Stainless steels, Alloy steels, Cast iron, Bronze alloys 

Elastomers:

Plastics:

PEEK, PPS, UHMW, Nylon . PTFE

Also Known As: 

Header Ring - Base Ring - Bottom Adapters   -  Energizing Ring   -  Thrust ring

Style V100 Vees conform to Army-Navy specification AN6225. These vees are used for pneumatic and low to medium duty hydraulic service. 

Style V400 heavier wall and cross section design will withstand  higher operating  pressures vs style V100

Style V600 higher-profile design minimizes the number of rings needed to fill the stuffing box. The rounded top of each ring forces the lips of the adjacent rings to flare radially.  The large void areas permit thermal expansion where binding may be an issue

Style 500 V-Packing is one of the most versatile V-packing designs used today.  The hinge design allows the sealing lips to remain in contact with the surface being sealed without putting undue stress on the sealing ring itself. 

 Benefits 

• The void between pressure rings acts as a lubrication reservoir 
• -Build in interference
• land adjustments not required 
• Low- and high-pressure range  

Commonly used for control valves, the thin legs allow for sealing with less compression vs other V-Ring designs.    

Common material is Unfilled PTFE, other materials available.   

*Wiper rings available 

Anti extrusion rings (Back-ups)  used to  help prevent extrusion.

Dual pressure set example 

Spring energized headed ring helps to prevent low pressure linkage and also helps to energized V-rings as pressure increases 

SPRING ENERGIZED SEALS

MORE INFORMATION

Elastomer Energized Headed Rings 

 DP header rings are primarily used in plunger packing sets. The header ring provides a dual purpose of wiper and helps to energize the pressure rings.

Material: NBR, HNBR, FKM  

Style PR PR header ring is the primary seal made of fabric and rubber. Seals both low and high pressures and helps to energize the pressure rings.  

Material  Fabric & NBR

(Duck and Rubber)

Style 500-T is same as style 500 except about twice as long.

Benefits

• Withstand higher pressures and loads than style 500
• Resists rollover
• Resists distortion
