nnnnGarlock GUARDIAN® 306 EZ-FLO® spool-type expansion
nnnnjoints feature an FEP lining that is fused to the body of
nnnnthe expansion joint.
nnnnThis product is designed for the chemical processing and
nnnnpulp & paper industries, where its ability to resist corrosive
nnnnattack at normal or elevated temperatures and pressures
nnnnis unequaled.
nnnnBenefits
nnnn■ FEP liner is non-contaminating and suits a wide range
nnnnof applications
nnnn■ Flowing arch design prevents media buildup and re-
nnnnduces turbulence and vibration
nnnn■ 250 psig (17 bar) pressure rating ensures longer ser-
nnnnvice life and consolidates inventory
nnnn■ Liner extends to outer diameter of flange to prevent
nnnnchemical attack on expansion joint flanges
nnnn■ Mechanically bonded liner resists delamination
nnnnDesign
nnnn■ Tube
nnnn• Seamless FEP lining extends to the outer edge of
nnnnthe flange; completely fused to the expansion joint
nnnnbody
