Adaptors | Flameproof & Increased Safety

Raxton Exd/Exe hazardous area reducers provide a means of electrical connection between different thread forms and sizes – reducers are ATEX Certified. They effectively reduce the threaded entry diameter of an enclosure to accept a smaller gland of alternative thread forms.

Standard Exe Exd reducers, manufactured by Raxton, have a hexagonal body, or for applications where space is a critical factor, reducers with a circular head can be offered having a diameter equal to the across flats dimension of the hexagonal head.

Raxton flameproof (Exd) and increased safety (Ex e) reducers are marked with the applicable approval number and size.

Certified reducers should be used following the basic rules in line with good engineering practice:- no more than one reducer should be used at one time.

reducer Thread selection

  • Isometric (ISO) to BS3643:1981 and ISO 965 Pts 1 & 3
  • Imperial (ET) to BS31:1940 (1979)
  • National Pipe Thread (NPT) to ANSI/ASME:1983
  • British Standard Pipe (BSP) to BS21:1985
  • Pg to DIN 40430:1971

These reducer selection tables identify the standard thread variations produced and are designed to assist the user in selecting the correct hazardous area Exe/Exd reducer suitable for use in Zone 1 or Zone 2 potentially explosive atmospheres according to the ATEX Directive.
