Sentry 2420-10-BL PTFE Bellows Kit Pulsation Dampeners

The Sentry 2420-10-BL PTFE Bellows Kit is an internal PTFE bellows assembly for pulsation dampener systems, delivering sealing, pressure stabilization, and chemical-resistant containment in industrial fluid handling. Brand: Sentry; Part Number: 2420-10-BL; Product Type: PTFE Bellows Kit; Function: pulsation dampening and pressure stabilization; Material: PTFE (Polytetrafluoroethylene); Compatibility: Sentry dampeners – 1, 175, and 370 cubic inch models; Kit Contents: bellows, O-rings, and mounting hardware; Installation: Internal dampener assembly. This kit is used inside Sentry dampeners to absorb pressure fluctuations, reduce vibration, and protect downstream equipment when handling corrosive or aggressive media, thanks to PTFE's chemical resistance, and it supports applications in chemical processing, water treatment, and pump systems. Common replacements include the Sentry 3020-10-BL PTFE Bellows Kit, Blacoh PTFE Bellows Replacement Kit, and the Sentry Diaphragm Repair Kit (model-specific equivalent).
