Mill-Duty Static Seal
Series 161: Mill-Duty Static Seal
The 161 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.
Installation
Benefits
No twisting or rolling during installation
Direct retrofit to O-Ring and backup ring designs
Extrusion resistant
Abrasion resistant polyurethane
Long life due to robust design
Applications
The 161 Series is used as the primary static seal in heavy duty steel and aluminum applications in severe conditions.
Typical applications include:
- Steel and Aluminum Processing
- Mobile Hydraulics
- Hydraulic Cylinder Repair
- Agricultural Hydraulics
- Construction Equipment
The 161 Series Static Seal features high-grade polyurethane. Standard materials are MP03 machined H-PU, available up to 2100 mm in diameter.
