Purpose-built Collet for CP860 Grinders

This Chicago Pneumatic C138727 collet is engineered for CP860, CP860E, CP860ES and CP860ESE pneumatic grinders. It serves as the split-sleeve gripping ring that secures tubing inside push-to-connect fittings. Technicians maintaining compatible Chicago Pneumatic tools will find it a direct replacement part.

Sealed Quick-Release Operation

Inward-facing teeth clamp the tubing while an internal O-ring maintains the pneumatic seal during normal grinder use. Depressing the collet releases the grip instantly for fast tubing changes. The design contains no moving parts beyond the split sleeve, so there is no additional noise, vibration or power draw introduced to the tool.

Drop-in Fit for Existing Fittings

The collet installs directly into the existing push-to-connect fitting on the grinder, requiring no adapters or re-plumbing. It frees up maintenance time by allowing tubing swaps without disconnecting the air supply or removing the tool from the work station. Compatibility is limited to the listed CP860-series models.

Questions about this item

How do I install the C138727 collet on my CP860ES grinder, and what step is often missed?

Slide the split-sleeve collet into the grinder's chuck until the inward-facing teeth engage the tubing; the step often missed is ensuring the internal O-ring seats fully to create the seal before locking the quick-release collar.

What maintenance or replacement will the C138727 collet need over time?

The internal O-ring and inward-facing teeth wear from repeated tubing changes; replace the collet when the O-ring no longer seals or the teeth fail to grip tubing securely on CP860, CP860E, CP860ES, or CP860ESE models.

What limit appears first when using the C138727 collet continuously on a CP860 grinder?

Heat buildup in the split-sleeve gripping ring reduces the O-ring's sealing ability and weakens the inward-facing teeth's grip on tubing during extended grinding sessions.
