The Custom Rubber Gaskets and Seals Experts

Rubber Gaskets and Seals

Rubber gaskets and seals prevent seepage of moisture or air in a multitude of applications. Qualiform is the source for custom rubber molding and manufactured rubber gaskets and rubber seals. No matter what application, Qualiform has the experience to solve a variety of sealing problems. We provide a comprehensive line of commercial and specification grade elastomers to fabricate a variety of rubber parts including

  • Rubber Gaskets
  • Rubber Seals
  • Rubber Washers

Qualiform’s experienced team can assist you with your custom rubber gasket or seal project.  Our technical staff considers many factors in the design process, so they can recommend the best method to meet your quality and cost requirements.  Furthermore, they can develop a new design if needed.

There are two separate stages in the life of a gasket or seal:

  • The part’s primary fit and function.
  • How well the part can endure its environment.

As a result, Qualiform’s experts consider both factors in the design stage of rubber gaskets, so they will not be the weakest link in a product. Similarly, the consider environmental factors in gasket or seal application, such as

  • Flammability – UL specifications, heat resistance
  • Function – the motion acting upon it
  • Impermeability – exposure to gases
  • Organic materials needs – fungus resistance, odor, tastelessness
  • Temperature extremes – heat, cold
  • Weather exposure – water, ozone, sunlight

Whether you need large or small runs, our manufacturing capabilities mean a prompt response to your sealing needs.

Static Rubber Seals

Where there is little or no motion of assembly parts on the seal.

An initial compression or intervallic compression (open and close) characterizes this type of seal:

  • A liquid seal in a hose joint
  • A door seal on a home

With use of a Static Seal, compression pressure operates in a vertical direction relative to the face of an O-ring or face gasket and constricts two different surfaces to eliminate gaps.

Dynamic Rubber Seals

Where there is repetitive motion of assembly parts on the seal.

Repeated actions on the seal, recurrent or intermittent, characterizes this type of seal:

  • shock absorption device
  • piston ring seal

Dynamic Seals are more complex than static seals because of the varying stress levels. In addition to Static Seal considerations, Qualiform engineers assess abrasion resistance because it is affected by the companion surface finishes. Other considerations include: compression set, temperature changes, thermal cycling, distortion, recovery speed after compression, physical strength, tensile strength and tear resistance. Qualiform engineers asses all of these environmental forces and provide the most efficient and cost effective methods to meet our customers’ quality and cost requirements.

Our technical staff is ready to assist you with all your custom rubber gasket and seal molding needs.
