This cast iron reducer features the highest quality, tandem HBNR
lip seals with a purgable grease cavity that gives all the protection of a conventional tacononite seal without the maintenance concerns.
Consequently, most commercially available HBNR
grades have relatively high viscosity; with the low end of the polymer Mooney viscosity in the range of about 60-65 (ML 1+4 at 100[degrees]C).
In some of these applications, only certain areas of the rubber article are exposed to these stringent conditions and part costs could be minimized by using a multilayered construction of HBNR
with other elastomers.
