National Hose & Accessory’s rubber expansion joints carry safety ratings exceeding product specifications in such areas as pressure and movement.

Expansion joints absorb movement, improve thermal stability, reduce mechanical noise and compensate for misalignment. This will improve factory performance, reliability and service life. These are engineered products designed to be inserted into piping that is rigid. Increase your equipment mechanical integrity and relieve system strain due to thermal change, wear, settling, pumping surges or stress from loads. Rubber expansion joints have various applications for the following industries:

  • Power Generation
  • Pulp and Paper
  • Chemical Processing
  • Water/Waste Water, Marine
  • Mining
  • Heating, Ventilating, and Air Conditioning

No matter what gasket or sealing material you need, National Hose & Accessory speaks your language. The language of sealing science.
