GUARDIAN® 306 EZ-FLO®
Garlock GUARDIAN® 306 EZ-FLO® spool-type
expansion joints feature an FEP lining that is fused to
the body of the expansion joint.
The GUARDIAN® 306 EZ-FLO® is designed for
the chemical processing and pulp & paper industries,
where its ability to resist corrosive attack at normal or
elevated temperatures and pressures is unequaled.
Benefts
¦ FEP liner is non-contaminating and suits a wide
range of applications
¦Flowing arch design prevents media buildup and
reduces turbulence and vibration
¦250 psig (17 bar) pressure rating ensures longer
service life and consolidates inventory
¦Liner extends to outer diameter of fange to prevent
chemical attack on expansion joint fanges
¦Mechanically bonded liner resists delamination
Design
¦ Tube
• Seamless FEP lining extends to the outer edge
of the fange; completely fused to the expansion
joint body
