Seal swell additives help to maintain the integrity of certain elastomeric materials used as seals, preventing elastomer shrinkage, brittleness and deterioration during service.

Seals are used within lubrication systems to isolate lubrication environments from harmful elements.  By protecting seals, Afton’s additives help maintain hydraulic pressure, allow simpler removal and replacement of malfunctioning parts, and help minimize lubricant contamination and loss.
