The KB112E chevron packing set has been modified with radiused intermediate chevron rings to improve high-pressure sealing.

The design of this set provides automatic pre-load which means the engineer doesn’t have to make manual adjustments to the seal gland or crush the seal which is common when using older rubber & fabric packing sets.

The intermediate V-ring/s can be stacked on top of each other to provide redundant sealing capability which is useful when the primary seal fails. The choice of too many V-rings though can see the packing set ‘burnout’ through increased friction; we recommend 1 ring only for piston applications and a maximum of 2.

Common materials are PU and POM, but several different materials can be provided to suit most applications – Please talk to our technical department if you need assistance with your application.
