The Chicago Pneumatic CP42 Series rivet squeezers set solid rivets with smooth compression instead of hammer blows, giving aerospace and sheet-metal shops uniform shop heads without hammer marks. Six models cover squeeze forces from 1,790 to 5,990 lbf, setting aluminum rivets up to 3/16 in. and steel up to 5/32 in., with alligator or C-style jaws that make it possible to work any rivet within 76 mm of an edge.
Compression riveting is quiet and nearly vibration-free the CP42 series measures 7277 dB(A) sound pressure with vibration below 2.5 m/s which keeps operators productive through full shifts of metal-structure repair and aerospace MRO. All six models connect through a 1/4 in. NPT inlet at 90 psi, and an in-line lubricator upstream keeps the air motor healthy. For blind rivets and rivet nuts, the companion CP988 series pneumatic riveters cover mandrel work, while demolition-class rivet cutting on structural steel belongs to our pneumatic rivet busters.

CP42 Rivet Squeezer FAQ
Which CP42 model do I need?
Pick by squeeze force and rivet size: forces run from 1,790 lbf on the CP4210AL up to 5,990 lbf on the CP4220AS and CP4220CS, with capacities from 3/32 in. aluminum at the light end to 3/16 in. aluminum and 5/32 in. steel on the strongest models.
Alligator or C-style jaws which should I choose?
Both jaw families make it possible to work any rivet within 76 mm of an edge; choose the style that gives the best access on your assembly, with alligator long, alligator short and C-short options across the six models.
How loud is a pneumatic rivet squeezer?
The CP42 series measures 7277 dB(A) sound pressure with vibration below 2.5 m/s, because compression riveting replaces hammer blows with a smooth squeeze.
What is the difference between a rivet squeezer and a rivet buster?
A rivet squeezer sets solid rivets by compression for aerospace and sheet-metal assembly; a rivet buster is a demolition-class tool that cuts old rivets out of structural steel the rivet buster buyers guide covers that side of the family.
