The 261 Series is a great replacement for standard large-diameter O-rings. This heavy duty static seal has a defined sealing lip manufactured from high-performance polyurethane. The square body profile prevents rolling in the groove, which is common with O-rings. The robust qualities of polyurethane allow the seal to be used without a backup ring. It is a substantial upgrade to the traditional O-ring and backup ring combination, which has been prone to rolling installation problems.
No twisting or rolling during installation
Direct retrofit to O-Ring and backup ring designs
The 261 Series Mill-Duty Static Seal is used as the primary static seal in heavy duty steel and aluminum applications and severe conditions.
The 261 Series Mill-Duty Static Seal features high-grade polyurethane. Standard materials are MP03 machined H-PU available up to 2100 mm in diameter.
