• Relative light weight
• Non-conductive
• Abrasion and corrosion resistant
• High fatigue resistance
• Wide material selection
• Movement achieved with relatively low force

Available in round or rectangular configurations, the DF-60 is designed for use in duct systems where pressure, abrasion and mechanical movement preclude the use of conventional ducting connectors. The external metal reinforcement and high strength synthetic reinforcing fabrics allow working pressures in excess of 25 PSIG. The wide arch design and rounded corners of the rectangular style allow for high movement capabilities while reducing fatigue due to flexing. Abrasion resistant rubbers allow the use of this expansion joint in applications such as discharge chutes, pneumatic conveyors and vibratory feeders. EVR DF-60 Expansion Joints are available in a wide range of elastomers and fabrics to suit most corrosive and temperature environments up to 400°F. To receive a design proposal, contact EVR to get a DF-60 Expansion Joint for your specific application requirements.
Unit of Measure

Available Elastomers

N/A Neoprene (CR)
Generally resistant to oil and grease, moderate chemicals, fats, many hydrocarbons and ozone. Resistant to barnacle growth.

Butyl (CIIR)
Good resistance to animal and vegetable fats, strong and oxidising chemicals, oils, heat and greases.

Ethylene Propylene Rubber (EPDM)
Most effective for applications involving water, steam or diluted acids.

Viton™ (FKM)
Resists solvents, halogenated hydrocarbons, oxygen, weather, ozone, oils and chemicals.

Teflon™ (AFMU)
TFE sheet or Teflon™ coated fibreglass used as a vapour barrier where condensation of corrosive gases may occur.

A high quality elastomer, recommended for all environments except those with sulphur gas (SO2 or SO3). Usable in -70 to 500° F applications.

Mineral Fibre
Used as insulation pillow and composite layer for service conditions up to 2500° F.
