Clear PVC Wire Reinforced Vacuum Hose.
Hoses are helium leak tested and guaranteed leak tight to less than 10^-8 atm-cc/sec and rated for full vacuum. Recommended for any vacuum service lines down to 10^-3 torr. NW Flanges are held in place by fixed crimped clamps on hoses rather than screw type clamps.
Custom lengths can be quoted upon request.
