The Blue-White 72000-550 Retrofit Kit is a genuine OEM upgrade solution for A-100N series peristaltic pumps shipped before September 1, 2015. This kit enables you to retrofit older pump heads so they can accept the newer style A-100N tube assemblies — restoring your pump to full functionality without replacing the entire unit.

With the included clear pump head cover and adhesive spacer pad, the retrofit ensures that new tubes are securely seated and correctly aligned. This rebuild kit is ideal for pool, spa, and industrial chemical feed systems, allowing you to extend the lifespan of your existing pump with modern, reliable tubing.
