For Clear & SS Vacuum Hoses, LACO offers both clear PVC wire reinforced vacuum hose with NW flanges and Thin Wall SS Metal Hoses and Medium Wall SS Metal hoses upon request.
Hoses are helium leak tested and guaranteed leak tight to less than 10-8 atm-cc/sec and rated for full vacuum
Clear hoses recommended for any vacuum service line down to 10-3 Torr
NW flanges on Clear hoses are held in place by fixed crimped clamps on hoses rather than screw type clamps
