Diesel Pro Power provides front and rear shaft seals engineered specifically for the Twin Disc MG506—delivering performance and longevity you can trust.

Premium Aftermarket Quality for Long-Lasting Performance

Diesel Pro Power’s seals for the Twin Disc MG506 are premium aftermarket components designed to meet or exceed OEM quality standards.
