Crown Engineering H24-36 Spiralink Coupler 321142-301 installing a high-efficiency coalescing filterThe Crown Engineering H24 36 Spiralink Coupler is a heavy duty, single spring replacement solution engineered for HVACR circulator pumps. Designed to replace the traditional failure prone OEM multi spring "fly away" couplings, this 5 8" x 5 8" CCW coupler features a robust one piece construction that significantly reduces friction and mechanical noise. The counter clockwise (CCW) rotation and dual 5 8 inch bore diameters ensure precise alignment
