Graphite Packings
Graphite Packings are intended to offer high temperature capability, good chemical resistance and markedly reduced spindle wear. By selecting or combining the many versions of Graphite Packings available – we are able to offer a versatile range of Graphite Packings with varied handling and performance characteristics. These include high conformability, resistance to extrusion, chemical purity, temperature and oxidation resistance amongst others.

K35 die-formed rings are unaffected by fluctuations during application, such as thermal cycling.
Hybrid Packings
HYBRID packings are suitable for those applications where an unusual combination of service demands are faced so a specially constructed HYBRID packing may be required.
This is achieved by combining two or more yarns by special braiding methods, and adding selected lubricants. These Hybrid packings are primarily designed for use in specialised duties, but can be equally effective in many more standard applications. KLINGER recommends HYBRID packings in difficult applications where high stresses are involved and the packing is required to offer a tight seal under high pressure, eg reciprocating pumps.

PTFE Packings
Packings made from PTFE (polytetrafluoroethylene) are a mainstay of the mechanical compression packing industry. PTFE is well known for its outstanding resistance to chemical attack, low coefficient of friction and wide temperature tolerance including cryogenic service. This wide flexibility makes PTFE packings a popular choice for those difficult applications where strong solvents, corrosive chemicals and oxidising media require to be sealed. KLINGER have harnessed these properties in our range of PTFE based gland packings to give an enormously wide sealing capability in both valve and pumping applications.

Synthetic Fibre Packings
An increasing variety of SYNTHETIC fibres are employed in the production of mechanical compression packings.
This is in response from industry for improvements in overall sealing capability. The demand by users for less leakage, downtime and wear combined with reasonable payback time remains the primary criteria for the use of SYNTHETIC packing. SYNTHETIC packings are increasingly finding favour because of the effective techniques employed by KLINGER in respect of the materials used, and in braiding and lubrication methods.
