4 in NPT Male ABS Adapter

This ZORO SELECT male adapter connects 4 in NPT threaded pipe to a 4 in female socket end in Schedule 40 ABS. The fitting measures 3 63/64 in overall length and suits 4 1/2 in outside diameter pipe. It is rated for gravity flow maximum operating pressure between -20 and 140 degrees Fahrenheit.

Installers needing a straight NPT to socket

Plumbers joining threaded and solvent-weld ABS systems in drainage or vent lines will find this adapter matches Schedule 40 dimensions. It is not intended for pressurised applications beyond gravity flow, nor for use with pipe schedules or materials other than ABS Schedule 40.

Schedule 40 ABS gravity-flow rating

The single specification that determines suitability is the gravity flow maximum operating pressure rating across a temperature range of -20 to 140 degrees Fahrenheit. Systems requiring higher pressure capacity or different temperature limits must use a different fitting class.

Questions about this item

Will the 4 in NPT male threads mate with my existing Schedule 40 ABS pipe?

Yes, the adapter is built for Schedule 40 ABS and has 4 in NPT male threads on one end and a 4 in female socket on the other.

How can I confirm the joint is leak-free after solvent-welding the socket end?

Pressurise the system slowly up to the gravity-flow rating and inspect the solvent-welded socket and threaded connection for any seepage.

Does the package include a thread sealant or gasket for the NPT side?

The adapter ships without a seal; you must supply thread tape or pipe dope for the NPT connection.
