  Compression Packing
High Performance Packing manufactured from Novoloid synthetic fibres. For use in all rotary applications requiring a resilient, conformable packing grade.
K4330 is only one of the extensive products in the KLINGER pump and valve sealing range. The range includes compression packings, moulded sets, low emission sets and specialised products.
This is an optimised range introduced to provide users with gland sealing products that meet today’s demanding services, offering effective and trouble-free sealing during application. To achieve this goal we have selected the best materials and the best production methods.
The result is the KLINGER pump and valve sealing range.
Ongoing Test& Development in line with KLINGER’s service and quality philosophy will ensure improved performance in your pump and valve applications.
K4330, is a soft, fibrous packing manufactured from synthetic Novoloid filaments with many of the attributes of other non-asbestos pump packings, but with the key benefits of improved lubricity and service life.
Golden in colour, K4330 is manufactured by our Klingerlock process, during which we add a controlled amount of PTFE. This produces a dense, deformable packing that is easy to handle.
K4330 has excellent chemical resistance and is employed as a replacement to PTFE grades due to the improved resistance to abrasive media it offers. Additionally K4330 will not extrude or harden, requiring minimum gland adjustment when installed. K4330 is thermally stable and will not expand or shrink during fluctuations in process conditions.
Unlike Aramid grades, which may be detrimental to shafts/sleeves its low oefficient of friction, offers significant improvements in rotary applications minimising equipment wear.
