GARFLEX® 8100
nnnnGARFLEX® expansion joints feature rugged yet flexible
nnnnnylon cord reinforcement in a molded, spherical bellows
nnnndesign that ensures an exceptional burst pressure rating.
nnnnThe streamlined flowing arch design reduces turbulence
nnnnand allows smooth, quiet flow—no need to fill the arch
nnnnand restrict its movement.
nnnnBenefits
nnnnFlowing arch design prevents sediment buildup and
nnnnreduces turbulence
nnnnFloating flanges can be rotated to accommodate
nnnntorsional misalignment
nnnnMolded spherical bellows accommodate up to one
nnnninch of axial movement and transverse deflection
nnnnNylon-reinforced nitrile tube earns high pressure rat-
nnnning without sacrificing flexibility; resists most hydro-
nnnncarbons, oils and gasoline
nnnnCan be installed against raised face pipe flanges
nnnnDesign
nnnn■ Tube
nnnn• Nitrile bellows with rugged nylon tire cord rein-
nnnnforcement ensure strength yet flexibility
nnnn• Incorporates a flowing arch design to eliminate
nnnnproduct buildup
nnnn■ Cover
nnnn• Homogeneous layer of neoprene coated with a
nnnnprotectant withstands weathering and ozone
nnnn■ Flanges
nnnn• Metal flanges with rust resistant coating
nnnnNote:
nnnnStyle 8100 expansion joints are supplied with rotating flanges drilled
nnnnto ANSI Class 150# specifications.
