Short answer
A size 3.0 nozzle flows 3.0 GPM at 4,000 PSI, and Cat Pumps gives it a 0.043 in orifice. By the formula Cat Pumps and General Pump publish, it flows about 2.60 GPM at 3,000 PSI and 2.12 GPM at 2,000 PSI (calculated). DEWALT sells size 3.0 tips (DXPA34ST) and a turbo nozzle (DXPA34TN), both on a 1/4 in quick-connect and rated to 3,400 PSI. MTM Hydro labels the 1.1 mm orifice in its PF22.2 foam cannon kit as size 3.0.

Key facts
- Orifice diameter
- Cat Pumps gives 0.043 in for a size 3.0 nozzle. MTM Hydro labels the 1.1 mm orifice in its PF22.2 foam cannon kit as size 3.0[1][2]MTM's figure is its own labeling of a foam cannon orifice.
- Flow at common pressures
- 3.0 GPM at 4,000 PSI (Cat Pumps). Calculated with the formula Cat Pumps and General Pump publish: about 1.84 GPM at 1,500 PSI, 2.12 at 2,000 PSI, 2.60 at 3,000 PSI and 2.77 at 3,400 PSI[1][3][4]Calculated values are reference math, not the measured output of any machine.
- Parts made in this size
- DEWALT DXPA34ST five-tip set (0, 15, 25, 40 degrees and soap) and DXPA34TN turbo nozzle, both 1/4 in quick-connect and rated to 3,400 PSI; MTM Hydro's 1.1 mm foam cannon orifice in the PF22.2 kit[5][6][2]DEWALT's DXPA34TN is for cold water only.
- Machines makers pair it with
- Not confirmedNo maker in the sources read pairs size 3.0 with a named machine.
- Spray angle
- Separate from size: Cat Pumps says spray angle does not affect nozzle flow; DEWALT's size 3.0 set comes in 0, 15, 25 and 40 degrees and soap[3][5]
- Wear
- Cat Pumps says worn nozzles are the most frequent cause of low pressure; replace a worn nozzle with the proper size, and never adjust the pressure regulating valve to make up for it[7]
- Not confirmed
- Not confirmedA General Pump chart diameter for size 3.0 was not recorded; no maker pairs the size with a named machine; DEWALT gives no GPM range or hot-water limit for its tips.
Watch out for
- DEWALT rates its size 3.0 tips and turbo nozzle to 3,400 PSI and its size 4.0 parts to 4,500 PSI; check the part's rating against your machine, not just the size.
- MTM's 1.1 mm (size 3.0) foam cannon orifice is below the 1.25 mm minimum Active gives for its Active 2.0.
- A size 3.0 tip and a 1/4 in quick-connect are different things: the size sets the flow, the quick-connect only the fit on the wand.

Questions
Is a 1.1 mm foam cannon orifice the same as size 3.0?
MTM Hydro labels the 1.1 mm orifice in its PF22.2 kit as size 3.0, and the 1.25 mm one installed as size 3.5. That is MTM's labeling for its own orifices. See foam cannon orifices.[2]
