Industrial Pressure Regulator for Plumbing Systems

The SharkBite 22999-0045 is a Series EB-75 pressure regulator built with an iron body for industrial plumbing applications. It features 1/2 inch NPT inlet and outlet connections and manages supply pressures up to 300 psi. The unit adjusts downstream pressure between 10 and 70 psi and operates at temperatures up to 180 degrees Fahrenheit.

Suited for Installers Needing Code-Compliant

This regulator meets ANSI, ASSE 1003, CAN 372, CAN 61, CSA B356, and NSF standards for potable water and industrial systems. It is not intended for applications requiring pressure settings outside the 10 to 70 psi range or for piping sizes other than 1/2 inch NPT. Buyers needing different connection types or higher temperature ratings should evaluate alternative models.

Standards-Certified Body Simplifies Approval

The included certifications cover health effects, lead-free compliance, and performance standards for water pressure reducing valves. This allows the unit to be specified in projects requiring ASSE 1003 or NSF 61 listing without additional documentation. The iron construction and fixed NPT threads mean no extra adapters or transition fittings are required for standard 1/2 inch pipe.

Questions about this item

Does this 1/2 in NPT pressure regulator connect directly to existing 1/2 in NPT plumbing without extra fittings?

Yes, the regulator has 1/2 in NPT inlet and outlet connections that match standard 1/2 in NPT pipe threads.

Will the 10 to 70 psi adjustment range cover the same outlet pressures my current regulator provides?

The adjustable range is 10 to 70 psi, so it can be set to any outlet pressure within that span.

After installation, how do I verify the regulator is holding the chosen outlet pressure?

Install a downstream pressure gauge, open a fixture, and confirm the gauge reads the set pressure within the 10 to 70 psi range.
