Fitting joints series TSVNA (AFC-MF)PURPOSE AND SCOPE OF APPLICATION

Explosion-proof fittings with two threaded connections. Used for connection of components of electrotechnical equipment in hazardous areas - terminal boxes, control cabinets, pipes, cable glands and other elements that are rigidly fastened in electrical pipe systems.

DESIGN 
- Three elements with independent rotation - connection of pipes is made without their rotation.
- Two connecting holes with male and female thread.
- Variations of connecting thread - for connection of pipe ends with the same or different size, as well as for connection with flexible hoses.

Scope of application – outdoor and indoor hazardous areas as per explosion protection marking - category II for gas subgroup IIA, IIB, IIC, zones 1, 2; category I for firedamp and dust РВ, РП, 1, 2, zones non-hazardous with dust and gas.
