PTFE & PVC Expansion Joints
OVERVIEW: Flexicraft PTFE and PTFE lined expansion joints are used for corrosive applications when other materials are inappropriate. Review the PTFE bellows expansion joint choices below to choose the model appropriate for your application.
METAL | RUBBER | PTFE & PVC | FLEXIBLE | BRAIDED | INDUSTRIAL HOSES
The Teflex joints are unreinforced PTFE. The 2-convolution joint is sometimes referred to as a "coupling". 1" to 12" diameters.
TEFSPOOL RUBBER EXPANSION JOINT
The Tefspool expansion joint is a rubber spool with an integral PTFE liner, giving it the strength and pressure rating of a rubber expansion joint, and the chemical resistance of PTFE. 1.5" to 24" diameters.
The PVC Ultrasphere Twin exapansion joints for PVC piping systems. They help eliminate vibration and noise from pumps, as well as allow for movement in the offset lateral direction, and in compression. Socket and NPT thread ends, with a rubber bellows. 3/4" to 3" diameters.
The Teflex joints are unreinforced PTFE. The 3-convolution joint is sometimes referred to as an "expansion joint". 1" to 12" diameters.
TEFBELLOWS PTFE LINED METAL EXPANSION JOINT
The Tefbellows is an expansion joint that combines the properties of metal and PTFE into the most advanced expansion joint available for highly corrosive piping systems. Normal design temperatures are from -300F to +400F, and they will retain their pressure carrying capacity up to 1,200F in an upset condition, sufficient time for system shut-down and replacement.
The Teflex joints are unreinforced PTFE. The 5-convolution joint is sometimes referred to as a "bellows". 1" to 12" diameters.
MODEL P & CP EXPANSION JOINTS
The Model P and CP are PVC/CPVC expansion joints for thermal expansion movement. Uses telescoping sections, sealed by O-rings. Available for 6" an 12" travels, in 1/2" to 14" diameters.
