5500 Flange Bolt Disc Springs
Chesterton 5500 Flange Bolt Disc Springs are engineered to sustain consistent gasket pressure in flange connections by compensating for relaxation and thermal cycling. These compact, high-strength disc springs stack in place of traditional washers to keep bolted joints tight and leak-free over time.
Designed for use in high-pressure, high-temperature, or vibration-prone environments, 5500 springs enhance sealing reliability and extend maintenance intervals, making them ideal for challenging industrial flange applications across industries such as oil and gas, chemical processing, power generation, and heavy manufacturing operations where performance and safety are critical and long-term durability is essential.
