Sealing Solution:
Now, Parker’s material portfolio includes three generations of coolant resistant FKM materials to resist extreme performance requirements as temperatures increase and we see increased service life. 1st generation coolant resistant materials VB253 and VB271 provided the performance required up tp 135°C in coolant in trucking. 2nd generation materials VG292 and VG323 have satisfied customers with performance up to 150°C in commercial trucks, light duty trucks, and automobiles – including many electric and hybrid vehicles. 3rd generation, VG310 was developed for higher temperatures up to 175°C and prolonged use in challenging longer duty cycles. For extreme performance requirements, cost effective FF156 is another option for even longer service life.
O-Rings, D-rings and other shapes can be molded with coolant resistant FKM for the most extreme engine applications.
Materials have been tested in the following coolant technologies:
- OAT (Organic Acid Technology)
- IAT (inorganic Acid Technology)
- NOAT (Nitrited Organic Acid Technology)
- Glycol (mix of glycol or propylene glycol and water, the most basic coolant)
- HOAT (hybrids that combine IAT and OAT)
The O-Ring & Engineered Seals (OES) Division continues to innovate and provide high performance materials for the next generation of Mobile Industrial and Automotive challenges.
