Volcano Silicon Sock for PT100

Standard Silicone Rubber boot for Volcano Hot end with PT100 thermistor cartridges.  

The PT100 style volcano as used on E3D volcano and our own Vulcan hotends is physically larger than the old style block as used on the Anycubic Vyper or Artillery Sidewinder hot ends. ( see second photo) 

Please check that you have the correct part.

Silicon socks are not suitable for very high print temperatures - you should consider a Brass or Plated copper block if you intend to print at over 300 Degrees Celsius
