Vibration Dampening Gaskets

Custom vibration dampening gaskets absorb shock and reduce unwanted noise.

Custom vibration dampening gaskets attenuate noise, vibration and harshness.

Gasketing materials can do more than provide cushioning and seal gaps. Specialized materials also reduce noise, vibration and harshness (NVH). In vehicles, appliances and heavy equipment, vibration dampening gaskets can help protect sensitive electronics from physical shock. Vibration dampening gaskets are used in applications from smartphones to commercial HVAC systems, extending equipment service life and making devices more comfortable for users.

Features and Benefits of Vibration Dampening Gaskets

Helps isolate vibration efficiently to keep internal components safe from damage.
The proper design can provide long-term durability to withstand the life of the product.
Available in a variety of material types, formulations and thicknesses for a wide range of applications.
Reduces noise in environments where it can become a problem for the user or other personnel.
By reducing vibration, you increase the long-term stability to keep large machines from moving/shifting during operation.
Adhesives can be applied for applications where stick in place gaskets are required or can help ease in installation.

Materials for Vibration Dampening Gaskets

Applications for Vibration Dampening Gaskets

Anti-vibration pads for equipment
Flat elastic bearings for HVAC equipment and subsystems (fans, chillers, pumps)
Decoupling of vents, pipes and walls
Isolating foundations for pumps, presses, generators or highly sensitive equipment
Noise, vibration, harshness pads for automotive interior applications
Protecting internal components in phones, tablets and computers

Designing your Vibration Dampening Gasket

Gasket Function

Gasket Function

Do you need the gasket to do more than dampen vibration such as seal out moisture and particulates?
Gasket Size

Gasket Size

Are there limitations on gasket format (die cut vs. stripping)?
Gap Spacing

Gap Spacing

What is the thickness range of the gap?


What high and low temperatures will the material reach and for how long?
Chemical Resistance

Chemical Resistance

Will the material be in contact with chemicals or fluids?


Could material outgassing be detrimental to components?
UV/Ozone resistance

UV/Ozone resistance

Will the gasket be exposed to the external elements such as sun, wind, rain or snow?


Does the gasket require an adhesive so that it can easily be stuck in place?
