  • Model NLC bellows expansion joints provide the perfect balance between value and performance. There are two standard lengths, and pressure ratings of 50, 150, and 250 psi. Available in 2" to any larger size needed.

  • Model N high corrugation bellows expansion joints allow for versatile use in movements and lengths. Available in 50 and 150psi versions from 3" to 36" diameters.

  • Model C ring controlled expansion joints provide control, safety, and long possible travels by utilizing equalizing rings. From 3" to 24" diameters.

  • The Bellows Connector is kept stocked with 150# C/S flanges and tie rods. Although it only comes in one configuration, it is an economical choice that is appropriate for many applications. 2" to 12" diameters.

  • Model EP externally pressurized expansion joints have long axial compressions of 4" and 8". Available in stocked 150psi, or 300psi versions. Diameters range from 2" to 36".

  • Flexicraft Compensators are used on pipe diameters from 3/4" to 4" when compression is required from thermal expansion. They are stocked in weld, thread, flanged ends.

  • Flexicraft 2S & 3S Compensators are used on pipe diameters from 3/4" to 4" when compression is required from thermal expansion on copper pipe. They come with sweat ends.

  • The R-Packed Expansion Joints are designed for thermal expansion applications with axial movements. These "slip type" packed joints can accommodate 4", 8", or 12" of compression for single designs, and double that for dual designs. There is never a concern that an unscheduled outage will occur due to the expansion joint. Available in 150 and 300 psi, and 2" to 24" diameters.

  • The Model NLC Sanitary Metal Bellows utilizes an integral silicone liner for food and similar service. Has a unique Clean-in-Place (CIP) smooth bore design. Available in 1-1/2" to 12" diameters.

  • 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.

  • Flexicraft provides a full range of metal bellows expansion joints designed for engine exhaust, including blowers, fans, diesel engine generators, marine exhaust, train locomotive, earthmoving equipment, and many other hot low pressure applications.

  • Metal bellows duct expansion joints are used in low pressure, higher temperature gas systems to compensate for thermal growth and vibration. Round or rectangular joints available in any size.

  • Model WD welded diaphragm expansion joints provide a high pressure alternative, being rated at 1000 psi. Avaialble in 1/2" to 12" diameters.
