Explosion-proof fitting connections TSNNA

Product Description

The TSNNA is an explosion-proof fitting with two external threads, designed for securely joining housings, pipes, and cable glands in hazardous areas. Its three independently rotating elements ensure installation without twisting the pipes, making the connection more convenient and efficient.

Advantages

  • External threads of different standards (NPT, M, G) allow connection of a wide range of equipment and accessories.
  • Wide temperature range and climatic versions - operation from -60 °C to +250 °C (including special cold versions down to -75 °C)
