Our RJT (Ring Joint Type) is the most widely used union in the UK and generally conforms to BS4825.
The RJT union is cost effective, easy to install and readily available. They are particularly popular in
applications where regular dismantling is required and can be forgiving in applications of tube misalignment.
The union comprises of a hexagonal nut, weld male, weld liner and nitrile joint ring supplied as standard,
all wetted parts are grade 316 stainless steel whilst the nut is 304. Joint rings are also available in EPDM,
viton, silicon and PTFE. Alongside our weld range of RJT we keep an extensive range of Expand Fittings from 1” – 4”.
