Honeywell 27518 Crankarm Swivel Ball Joint is an HVAC actuator linkage component designed for use with 5/16-inch diameter push rods.
Its swivel configuration helps maintain proper linkage alignment and smooth mechanical movement, while the 1/4"-28 UNF male thread provides a secure connection for damper and valve actuator assemblies.
The 27518 is compatible with multiple Honeywell MS and ML actuator series, including:
| MS3103 | MS3105 |
| MS4103 | MS4105 |
| MS7403 | MS7405 |
| MS7503 | MS7505 |
| MS8103 | MS8105 |
