Value Brand Pressure Regulator Brass 300 psi 30PT99

SKU CH-ABBY-VN986

Brass pressure regulator handles 300 psi maximum inlet pressure and adjusts outlet flow from 30 to 50 psi for non-potable water systems

  • Regulates pressure down to 30–50 psi for consistent flow
  • Brass body withstands 300 psi maximum inlet pressure
  • Operates up to 140 °F for hot non-potable water
  • EPDM and Buna-N seals resist wear and leakage
  • Compact 2 1/8 in length fits tight installations

Pressure Regulator for Non-Potable Water

This brass pressure regulator controls flow in non-potable water systems. It accepts a maximum inlet pressure of 300 psi and reduces it to an adjustable range between 3 and 50 psi. The unit is designed for cold water use up to 140 degrees Fahrenheit.

Suitable for Low-Pressure Brass Installations

This part fits plumbing lines with 3/8 inch inlets and outlets using EPDM and Buna-N seals. It is not suitable for drinking water supply lines. Buyers needing potable water certification or different connection sizes should look at alternative components.

Maximum Inlet Pressure 300 psi

The 300 psi maximum inlet rating is the critical limit for system compatibility. Exceeding this pressure risks damage to the regulator body and seals. Verify your supply pressure stays at or below this figure before installation.

What pipe size and thread type are needed to install this 3/8 in regulator?

It connects to 3/8 in pipe with matching threads; the inlet and outlet are both 3/8 in.

How do you set the pressure on this 30PT99 without a gauge port?

Adjust the setting screw while measuring pressure downstream with a separate gauge; the body has no built-in gauge port.
