Norgren 60351 V-ring U-cup Piston Cup Seal

Product Description

The NORGREN 60351 is a V-ring and U-cup piston cup seal designed for use in pneumatic and hydraulic cylinder assemblies. This seal type creates a dynamic sealing interface between a piston and cylinder bore, preventing fluid or air bypass during actuator stroke cycles. Licensed industrial mechanics, fluid power technicians, and maintenance professionals install this style of seal during cylinder rebuilds or scheduled preventive maintenance. The 60351 is a replacement-grade component intended to restore cylinder function to original operating specs.

V-ring and U-cup piston cup seals are common in pneumatic cylinders, hydraulic actuators, and fluid power systems found in industrial automation, process equipment, and manufacturing environments. This seal fits into piston grooves and relies on system pressure to energize the sealing lip, making it effective across a range of operating pressures. The NORGREN 60351 is sold as a single-piece unit, appropriate for targeted seal replacement rather than full kit rebuilds.

Key Features

• V-ring and U-cup geometry provides pressure-energized dynamic sealing on piston assemblies
• Single-piece replacement unit for targeted cylinder service work
• Designed for pneumatic and hydraulic cylinder piston applications
• Compact form factor suitable for standard piston groove installations
• Sold individually with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement piston cup seal for pneumatic and hydraulic cylinder assemblies requiring V-ring or U-cup style dynamic seals.

Installation Notes

Installation of piston cup seals is performed by fluid power technicians or industrial maintenance mechanics. Depressurize and isolate the cylinder from all fluid or air supply before disassembly. Inspect the cylinder bore and piston groove for wear or scoring before installing the new seal. Lubricate the seal lip with a compatible fluid prior to assembly to prevent damage during initial stroke.
