150 & 250 General Purpose Cartridge Seals
Cost-Effective Option for General Purpose Applications
The Chesterton 150 & 250 seals are a value leader in its class. It is the ideal mechanical seal to reduce high maintenance costs and prevent wasteful leakage, shaft fretting damage, and inefficient downtime.
The 150L/250L features a single screw lock ring that uniformly claps the seal to the shaft and simplifies removal in fluids that tend to set or clog around the seal.
