PVC union

PVC unions are designed to assemble two pieces of pipe together and will leave the ability to disassemble the pipe with the union ends. Unions are used in systems that may need preventative maintenance or scheduled work within the piping system. Unions are manufactured with socket glue ends, female threaded ends and with one end socket one end threaded.

About size (OD is outside diameter, DN is inner diameter) for example, 1″ pipe mean pipe outside diameter is 32mm, but 1″ fittings means fittings inner size is 32mm, so correct pipeline is 1” pipe+1” fittings )

1/2″= OD20MM= DN15,       3/4″= OD25MM=DN20,      1″= OD32MM= DN25
1-1/2″= OD40MM= DN32,      2″= OD63MM= DN50,      2-1/2″=OD75MM= DN65
3″ =OD90MM= DN80,      4″ =OD110MM= DN100,      5″= OD140MM= DN125
6″= OD160MM= DN150,      8″= OD200MM= DN200.
