4 Port Style
[Click More Info for psi choices]

• Just match up the on/off pressure from yours to the ones below. Example 030/40 psi  means 30 psi on and 40 psi off.
• All work for 110 or 220V.
  
• 4  1/4" FPT ports on bottom/side for safety valve, gauge, et al unless otherwise noted.
• Most have on/off switch unless otherwise noted.
• If your pressure switch is leaking out of the small bleeder valve on the side or if located underneath, order a tank check valve instead, your pressure switch is ok.
