Description
The Chicago Pneumatic CP 4160 is the short-stroke entry in CP's pneumatic rivet-buster family, sized below the longer-stroke CP 4608 (8 in.) and CP 4611 (11 in.) for tight-access, overhead, and one-handed work. The CPS Control Power System distinguishes the CP 4160 with three integrated engineering features: teasing throttle, Boyer valve, and durometer-rubber buffer ring.
- CPS Control Power System pairs a teasing throttle, Boyer valve for extended cylinder stroke, and durometer-rubber buffer ring for cylinder and piston life.
- Wear-indicating groove on the lower sleeve signals when the buffer ring needs replacement for shop-maintained tools.
- Delivers 1,100 BPM at 44 CFM consumption at 90 PSI through a 1/2 in. NPT inlet.
- D-handle (CP 4160 D): 25 lb, 20-1/2 in. overall, inside trigger for general demolition with adequate overhead clearance.
- Open grip (CP 4160 P): 24 lb, 20-1/2 in. overall, outside trigger for tight-overhead, underdeck, and finger-sleeve protection work.
- Stepped hardened-steel piston prevents accidental ejection; forged-steel handle construction across both variants.
- Built for bridge-deck and parking-garage concrete demolition, structural-steel rivet removal, tank cutting, and drift-pin driving.
- Both variants accept the Jumbo 11X (.866 in.) shank; Crowder Supply stocks the full rivet-buster steel range plus CPS-system service parts.
