O-rings for marine engines

Usage summary

Coolant inside large diesel engines contains anti-corrosive additives and some of these can damage FKM. Because of this, the higher cost product, FFKM, is sometimes used. However it is known that leakage problems can occur due to its poor elasticity.
AFLAS® has similar chemical resistance to FFKM and better elasticity than FFKM. AFLAS® not only has a cost advantage but also a longer service life.
