The Stenner MCFC5AY Index Pin Assembly with Lifter delivers the precision dosing control that pool service and maintenance contractors depend on for accurate chemical injection systems. This complete assembly includes carbide-tipped pin, lifter, holder, and spring components essential for maintaining proper feed rate control in Stenner Classic Series pumps.

Professional Service Benefits

Designed for pool contractors who demand reliable chemical dosing accuracy, this assembly ensures consistent injection rates that protect your service reputation. The carbide tip provides extended wear resistance, reducing callback frequency and maintenance costs. When the index pin fails to engage properly, pumps stop injecting - making this a critical component for uninterrupted pool chemical management.
