RJT Unions (Ring Joint Type) are very popular in the UK and are often referred to as the standard union for hygienic fittings. They are manufactured to BS 4825 part 5 and consist of a hexagon nut, a male part and a pressed weld liner. The O-Ring style seal is available in a range of materials and leaves a small crevice where the liner and male part overlap. RJT unions are often preferred for use with frequently dismantled sections of pipework.
