2" Grooved End x Weld Nipple Adapter

The AVN2000-200 combines a 2" grooved connection and a 2" weld end in one straight fitting. This allows a mechanically joined grooved section to transition directly into piping that continues as a welded assembly.

The grooved side should be matched with the correct clamp and gasket system, while the weld side should align with the mating pipe before fabrication begins. Both connection styles should be confirmed so the adapter fits the intended layout without unnecessary additional fittings.

Dixon manufactures AVN2000-200 from aluminum as the 2" aluminum option in its Grooved End x Weld Nipple family. The same family is also offered in carbon steel and 316 stainless steel for systems requiring different material choices.

Material compatibility should be reviewed against the surrounding piping, transferred product, and operating environment before installation. The welding procedure must also be suitable for aluminum so the finished joint maintains proper fit and integrity.

Dixon lists AVN2000-200 with a 2" end-to-end dimension, creating a compact straight transition between the grooved and weld connections. The short body can be useful where available piping space is limited and a direct change in connection method is required.

Verify the available installation space and surrounding pipe alignment before welding. Proper positioning helps keep the groove accessible for the mating clamp while preventing unnecessary stress on the welded joint or connected piping.

Dixon lists this grooved x weld nipple family for gasoline and diesel service, including E100 ethanol and B100 biodiesel compatibility. This supports use in compatible tanker, petroleum-transfer, and related fluid-handling piping systems.

System compatibility should still be reviewed as a complete assembly, including the clamp gasket, adjoining pipe materials, transferred media, and operating conditions. Inspect both the finished weld and grooved connection before the system is returned to service.
