Information

Body: Aluminum, turned, with bright finish
Symbols laser engraved  
Seal: Viton rubber

Shipping

The seal is retained in a groove undercut in the mating face, which prevents it from dropping out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing.  
Maximum heat resistance: 200°C (390°F).
