4" Aluminum Grooved End x Weld End Adapter Nipple

The AVN4000-200 combines two different connection styles in a single fitting. One end connects into a compatible grooved piping system while the opposite end provides a weldable transition point.

This arrangement can simplify installations where grooved components need to transition into welded piping. Confirm both connection requirements before selecting the fitting.

Dixon identifies AVN4000-200 as the aluminum version of the 4" grooved end x weld nipple. The same product family is also offered in carbon steel and 316 stainless steel configurations.

Material compatibility should be confirmed with the connected piping, transferred media, and welding procedure. Use appropriate practices for welding aluminum components.

Dixon lists AVN4000-200 with a 4" nominal size. Both the grooved-system connection and the weld-side installation should be checked against the surrounding piping dimensions before fabrication.

Do not select the fitting by appearance alone. Verify the exact AVN4000-200 part number and nominal size before ordering or welding the component into the system.

The grooved end should be installed with compatible grooved-system components while the weld end requires a suitable welding procedure for the aluminum fitting and mating pipe.

Confirm alignment before welding so the finished assembly does not place unnecessary stress on the grooved connection. Inspect both the welded joint and grooved connection before service.
