Model:34.142.116-iz▼NW/KF Aluminum Edge Seal
NW flange can be used for ultra-high vacuum (in the 10-⁹Pa range).
One-time use only, since the edge is crushed and sealed.
Use metal seal clamps.
High temperature 150°C
Low temperature -270°C
Suitable for radiation resistant and nuclear applications
Clean room applications
Outer type is for pressurized applications
※Not for use with glass or aluminum flanges.
