Chesterton’s 5500 Flange Bolt Disc Springs are manufactured from a specialized stainless steel alloy. This material was selected for its best characteristics against stress corrosion cracking.

Bolted, gasketed joints are subjected to mechanical shock, pressure surges or thermal expansion and contraction and are prone to leakage. Disc springs are an elastic mechanical element which compensate for these factors by maintaining bolt force under these conditions.

• Automatically maintains uniform clamping force
• Compensates for thermal expansion and contraction
• Absorbs vibrational shock, dampens effects of common pressure surges, prevents gasketing blowouts
