The three-piece unions are designed to allow the connection between conduit equipment and enclosures thanks to the independent rotation of their ends, available with a male or female threads. The three-piece unions are available in the following configurations:

- male - male: BMM (IIB gas group) and RMM (IIC gas group)

The materials used to manufacture the cable glands have been studied to grant the maximum protection against the highly corrosive agents present in these industries.
They are available in:
• galvanized steel
• stainless steel AISI 316
The O-ring and internal gaskets are made of EPDM (-20°c / +80°C) and, for low and high temperature environment, of silicone (-45°C / +125°C).
The three-piece unions are available, as standard, with NPT or Metric threads. Other thread types can be available upon request.
