Zoro Select GRUVLOK 390017440 Reducing Tee 4 x 4 x 3 In Ductile Iron Orange
Ductile iron reducing tee with grooved connections rated 750 PSI from -40 to 230 F for potable water use
- Operates down to -40 °F for cold-system reliability
- Withstands 750 PSI for high-pressure grooved piping
- Handles fluid up to 230 °F in hot-water service
- Ductile iron construction resists corrosion and mechanical stress
- Certified for potable water use in plumbing systems
Reducing Tee 4 x 4 x 3 In
The GRUVLOK reducing tee joins a 3-inch branch to a 4-inch grooved main in ductile iron. It suits mechanical piping installers who need a factory-finished fitting for water distribution systems. The orange coating identifies the component on site and resists handling damage during assembly.
Pressure 750 PSI temperature -40 to 230 F
The fitting is rated for 750 PSI working pressure and operates from -40 to 230 degrees Fahrenheit. These limits define the maximum conditions for potable water service; exceeding either value voids the certified performance. Designers must verify that system surge pressures and sustained temperatures remain within this envelope before specifying the tee.
Certified potable water upgrade
The ductile iron construction and potable water certification replace uncoated or non-listed fittings in municipal and commercial supply lines. The jump is worth it when code requires listed components for drinking water contact or when system pressure approaches the 750 PSI rating of this tee.

Questions about this item
Should I select the 4 x 4 x 3 inch reducing tee or a different size for my piping layout?
Choose this reducing tee when your main run uses 4 inch grooved pipe and you need a 3 inch branch; the nominal size is fixed at 4 x 4 x 3 inches.
What does the 750 PSI pressure rating mean once the tee is installed in a working system?
The 750 PSI rating is the maximum working pressure the ductile iron body can handle at temperatures between -40 and 230 F.
How does the grooved connection standard limit what pipe I can join with this tee?
The grooved ends accept standard roll-grooved or cut-grooved pipe of the matching nominal sizes, sealing with a compatible gasket and coupling.
