Fleck 1.5" SS Meter Union, M x F

The Fleck 1.5" Stainless Steel Meter Union (FL15M-SS-UNION, also referenced as FL44024) is a genuine Pentair connection fitting with a male-by-female (M x F) configuration. This 1-1/2" union joins the metering section of a large Fleck control valve to the system plumbing, allowing the meter to be connected and later disconnected for service without cutting pipe. The union design is a key convenience on larger systems where serviceability matters.

Stainless steel construction makes this union especially well suited to demanding, high-flow installations and environments where corrosion is a concern. The MxF threading lets it mate one threaded end into the valve or meter while the union nut connects to the opposing plumbing, creating a serviceable joint that breaks apart cleanly when maintenance is required.

• Genuine Fleck 1-1/2" stainless steel meter union
• Male x female (MxF) threaded configuration
• Connects large-valve metering to system plumbing
• Stainless build for corrosion resistance and strength
• Serviceable union for easy meter removal
• Also cross-referenced as part FL44024

On larger residential and light-commercial Fleck systems, a robust, leak-free meter connection is essential to both accurate flow sensing and trouble-free maintenance. Because these systems move significant volumes of water, the connection must hold up under higher pressures and flow rates without weeping or working loose. Stainless steel provides the strength and corrosion resistance to do exactly that over a long service life.

The union design is a major practical benefit: it lets a technician disconnect the meter for cleaning, inspection, or replacement without disturbing the rest of the plumbing or cutting and resoldering pipe. That saves time on every service visit and reduces the risk of collateral damage to surrounding connections. Installing this genuine stainless union ensures a strong, corrosion-resistant joint that seals reliably and stands up to high-flow service, keeping a large Fleck-equipped system dependable and easy to maintain.

For installers handling larger Fleck systems, a stainless meter union is the kind of fitting that pays for itself in time saved on future service, since the meter can be removed and reinstalled without touching the surrounding plumbing. Its corrosion resistance also means the joint stays sound and easy to break apart even after years in a humid mechanical room, making routine cleaning and inspection of the meter far simpler than a soldered connection would allow.
