SPOOL (Yale YT1701855)

A damaged spool can disrupt the directional control of fluid flow within a valve assembly. This aftermarket replacement part references Yale as the OE maker and cross-references part number YT1701855. The spool's plain mechanical function is to slide within a bore to open or close fluid passages. A concrete generic failure consequence is that a stuck or worn spool may cause erratic actuator movement or complete loss of function. Keeping a spool in sound condition helps maintain consistent system response during operation. Verify the serial number or application, then call (562) 693-7748. No additional specifications or material qualifiers are listed for this part.
