ensuring stable combustion performance across the full firing rate

making it a critical component for HVACR professionals seeking dependability in pressurized thermal systems and industrial boiler applications

Enhanced Durability: Constructed from high-impact

Field-made wiring often lacks the proper gauge and terminal crimp integrity required for UL-rated system performance

reducing the risk of premature high-limit trips

Armstrong Fluid Technology 871101-384 Ball Bearing 321142-301 ensuring stable combustion performance acrossThe Armstrong Fluid Technology 871101 384 Ball Bearing is a high performance inboard ball bearing engineered specifically for professional HVAC and fluid flow systems. Designed for use in Armstrong Series 4030 pumps with "M" style bearing assemblies, this component supports 213 215T frame sizes and pump models like the 2x1. 5x10 and 3x2. 5x8. This permanently lubricated bearing features a double shielded design (6209 2RS) to prevent contamination
