Spiralink Flexible Spring Circulator Coupling

Spiralink is a permanent replacement for the failure-prone 4-spring, "fly away" coupling used as original equipment in B & G circulators and clones by Armstrong, White-Rogers, Taco, and others.

Spiralink's single spring acts as a universal joint with 3-dimensional flexibility that compensates for any degree of shaft misalignment. The one-piece design has no connecting parts to produce the friction that causes noise, wear and early failure of old-style couplings.

Spiralink protects bearing assemblies from damage by broken couplings, and its flex reduces the torque load on bearings and seals. On top of that, it's far easier to install, especially in awkward locations.
