SPEEDAIRE 3CRH4 air riveter 1/4 in FNPT aluminum
Air-powered riveter pulls blind rivets up to 3/16 in. aluminum with 940 lbf force at 90 psi
- Delivers 940 lbf pulling force for secure blind rivet joints
- Operates at 90 psi with a 70–100 psi range for flexible compressor pairing
- Consumes only .55 cfm to reduce air supply demand
- Accepts aluminium blind rivets from 3/32 in to 3/16 in for versatile fastening
- 1/4 in FNPT inlet connects directly to standard 3/8 in minimum hose
SPEEDAIRE 3CRH4 air riveter
The SPEEDAIRE 3CRH4 is a pneumatic riveter built for general-duty fastening with blind rivets. It accepts aluminum rivets in 3/32 in, 1/8 in, 5/32 in and 3/16 in diameters. The tool connects via a 1/4 in FNPT air inlet and requires a minimum 3/8 in hose. It is suited for assembly and repair tasks where portable air power is available.
Air consumption and operating range
The riveter draws 0.55 cfm at a working pressure of 90 psi. It operates between a minimum of 70 psi and a maximum of 100 psi. Exhaust exits from the side of the aluminum body. These figures describe normal use when the tool is supplied with clean, regulated compressed air.
Sustained-load behaviour
Under continuous operation the tool delivers a pulling force of 1,940 lbf within the stated pressure band. Performance remains consistent as long as supply pressure stays between 70 and 100 psi and the hose meets the 3/8 in minimum. The general-duty rating indicates the design is intended for intermittent rather than high-volume production cycles.

Questions about this item
How do I install the 1/4 in FNPT air inlet and what step do people often miss?
Connect a 3/8 in minimum hose to the 1/4 in NPT female inlet using thread sealant; the step many miss is verifying the compressor delivers 90 psi at the tool, not just at the tank.
What maintenance will this riveter need later?
Lubricate the air motor daily with pneumatic tool oil, drain the compressor tank regularly to keep moisture out, and inspect the jaw assembly for wear after extended use.
What limit appears first during sustained riveting?
The 0.55 cfm air consumption means a small compressor will drop below the 70 psi minimum pressure first, causing pulling force to fall under the 1,940 lbf rating.
