Merkel Unival 6323

Merkel Unival 6323 consists of graphite filled, oiled PTFE yarn. Due to a special braid structure the advantages that this material offers (low thermal expansion and excellent heat conduction) are optimally exploited.

Merkel Unival 6323 is a very flexible packing and seals reliably with a minimum of gland pressure, even against thin liquid media that have a tendency to creep. It can also withstand dry friction up to a certain limit. The material used are approved for use in food processing industry MPA.

• Ability to run at high speeds
• Longer service life
• Low leakage with a minimum of gland pressure.

Application
