Typical Rubber Expansion Joint Applications
Industrial ApplicationsPiping installations are one of the most important locations for Unaflex® Expansion Joints as they compensate for the thermal expansion and contraction in the line, as well as reduce the transmission of noise and vibration. |

Heating/Air Conditioning and VentilatingUnaflex® Expansion Joints are used on the header connections to the condenser and to the cooler, as well as in the water circulating lines on both hot and chilled water lines. They will relieve stresses caused by changes in temperature as well as eliminate the transmission of noise and vibration. |

Marine ApplicationsUnaflex® Expansion Joints eliminate destructive electrolytic action, as well as insulate the transmission of noise and vibration. They are approved by U.S. Navy and U.S. Coast Guard and conform to ABS requirements. Special fire retardant expansion joints conforming to MIL E-15330D are also available. |

Central Power StationsDue to their compactness and ease with which they accommodate all types of movement, Unaflex® Expansion Joints are adaptable to a variety of uses in central power plants. Applications include condenser auxiliary exhaust lines, connections to air ejector, condensate pump, and low-pressure feed suction lines. Special joints available for temperatures up to 350°F and 400°F in flue duct applications. |
Sewage Treatment PlantsUnaflex® Rubber Expansion Joints are used on the aeration lines, grit pump line, raw sewage lines and sludge pumps. |
