Set and maintain the pressure of your compressed air. These regulators connect to other Wilkerson units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. They’re relieving, so they will exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.

Joiner clamps (sold separately) create compact, airtight connections between components. All include a wall-mounting bracket, except for clamps in the R90 series.

Fit a nonrelieving diaphragm assembly (sold separately) to these regulators to stop them from exhausting excess downstream pressure. They’re helpful if you’re using a gas you don’t want automatically released into the air, such as an expensive noble gas.
