Northern Industrial Supply Co. (NISCO) can supply a complete range of elastomer expansion joints. These expansion joints can accommodate all types of movement in piping systems, including axial, lateral, torsion, and angular. They feature fully molded corners to eliminate the chance of corner failure, and are available in high temperature designs. Some of the elastomers available include EPDM, butyl, Viton, nitrile, neoprene, gum rubber, NDF-61 EPDM, and FDA-approved compounds. These expansion joints. In addition to elastomeric joints, we can offer a wide range of fabric and metallic expansion joints.

Elastomer expansion joints

Elastomeric expansion joints can absorb motion and displacement, dampen vibrations, and prevent pipe buckling or fracture. For instance, the series 300 features a multiple-arch design to handle extreme movements. It consists of an elastomeric tube with fabric or metal carcass, cover, and reinforcement. It is capable of managing a wide range of temperatures and pressures, and is well suited to sludge, slurry, and waste water applications.

Another example is the Series 320 EZ offers a low spring rate and is ideal for use with FRP piping. It also features light weight so it is easy to handle and only requires a light anchoring system. It is available in a nitrile version that is resistant to oils, fats, chemicals, hydraulic fluids, and more.

• Some of the other elastomer expansion joints available include:
• Series 320 M designed for full vacuum with several options for tube and cover materials.
• Series 200 & 300 are designed for high pressure applications.
• Series 980 has a floating flange design and is perfect for HVAC, marine, or water line applications.
• PTFE 800 series can handle the most extreme applications and are supplied with ductile iron flanges and control units
