Whether it is air, steam, water or some other fluid that being moved, maintaining proper seals between and within parts of a system is important for function, efficiency, and safety. Pressure-bearing equipment of all kinds relies on good seals to function properly – which is why you find gaskets in all sorts of shapes, sizes, and materials.

Do you have questions about gaskets?

Some steam traps have replaceable gaskets that allow them to function properly under various working temperature and pressure loads. Valves have seals and packing that permit them to control flow under different conditions. Flanges have gaskets between them to ensure a tight seal between piping and equipment.  

Gaskets can be found in:

  • Repairing equipment such as steam traps, valves, heat exchangers, filters, etc.
  • Replacement after boiler and system inspections
  • Joining flanged sections of pipe

Leaks within equipment or between pipe connections make for energy, pressure and fluid losses which have to be made up for, driving up costs. Leaks can be dangerous to workers and to the public, whether as a slip and fall hazard or as exposure to fluids subject to any combination of temperature, pressure or toxicity.

Depending on the pressure and application, you will encounter steam service gaskets in black fiber, EPDM, PTFE (Teflon), synthetics like Durlon 8500, graphite, and many others.
