Threaded x threaded fittings connect to ABS (acrylonitrile butadiene styrene) pipe and are threaded on all connection ends. Female threads are on the inside of a fitting. Male threads are on the outside of a fitting and screw into the female threads. Threaded connections use PTFE tape to secure seal.

Threaded x spigot fittings connect with ABS (acrylonitrile butadiene styrene) pipe. These fittings include at least one threaded end and one spigot (or street) end. Female threads are on the inside of a fitting. Male threads are on the outside of a fitting and screw into the female threads. Threaded connections use PTFE tape to secure seal. Spigot fittings connect to another fitting (not directly to a pipe), and require glue or adhesive to secure the connection.

Socket x threaded fittings connect with ABS (acrylonitrile butadiene styrene) pipe and have at least one threaded end and one socket (hub or slip) fitting end. Female threads are on the inside of a fitting. Male threads are on the outside of a fitting and screw into the female threads. Threaded connections use PTFE tape to secure seal.

Socket x socket fittings, also called slip or hub fittings, include socket ends on all fitting connection ends. The socket ends fit over the end of an ABS (acrylonitrile butadiene styrene) pipe and require glue or adhesive to secure the connection.

Socket x spigot fittings connect with ABS (acrylonitrile butadiene styrene) pipe. These fittings include a socket (hub or slip) end that fits over a pipe and a spigot (also known as street) end that fits inside a socket. The spigot end is needed when a fitting connects to another fitting (not directly to a pipe). These fittings require glue or adhesive to seal the connection.
