Why TrueSeal™ valves and fittings with Kynar®?

Your choice over stainless steel – Aside from the obvious benefits of lighter system weight and faster assembly, water systems built with TrueSeal™ fittings and valves made from Kynar® PVDF offer significant advantages over the use of stainless steel. TrueSeal™ potable water fittings advantages include:

  • Better performance in corrosive environments, requiring no passivation
  • Smooth surface enables products using Kynar® PVDF to more easily transport fluid and reduce the likelihood of biomass growth
  • Kynar® systems become cleaner over time because of its low leachables and extractables versus stainless steel
  • Resistant to a wide range of sterilization chemicals, making products using Kynar® ideal for applications requiring high purity water.


Robust push-to-connect fittings ideal for water treatment and harsh chemical environments. Available in several materials. Parker TrueSeal are widely accepted in water conditioning, filtration, and reverse osmosis applications, and on water, soft drink, beer, wine, and condiment dispensing systems.
