Hosexpress is readily available to help answer any of your expansion joint questions for your particular industry types.

Industrial Applications:

UNAFLEX® expansion joints help to compensate for the thermal expansion and contraction in the lines. These expansion joints also reduce the transmission of vibration and noise. Piping installations are important locations for the UNAFLEX® expansion joints in the Industrial industries.

Heating/Air Conditioning and Ventilating:

UNAFLEX® expansion joints are the ideal expansion joints used on the header connections to the condenser. They also are used on the cooler as well as the water circulating lines for both hot and cold water lines. When using UNAFLEX® expansion joints, you will notice how they help release stresses caused by changes in temperature, and how these expansion joint eliminate the transmission of vibrations and noise.

Marine Applications:
