What are natural rubber gaskets

Natural rubber gaskets are sealing components manufactured from NR (natural rubber), known for its high elasticity, resilience and mechanical strength. These gaskets provide an effective seal in applications where flexibility and surface conformity are required.

Natural rubber gaskets are commonly used for general-purpose sealing tasks where exposure to oils, fuels or aggressive chemicals is limited.

When do you need NR gaskets

NR gaskets are used when a soft, elastic sealing solution is required for low to moderate pressure applications. They perform well in installations involving water, air or neutral media, where good compression recovery is important.

These gaskets are particularly suitable for applications where vibration damping or repeated compression plays a role.

Applications of natural rubber gaskets

Natural rubber gaskets are applied in pipe connections, mechanical assemblies, water systems and general industrial equipment. They are widely used in maintenance environments and installations where flexibility and wear resistance are key requirements.

Depending on the application, NR gaskets can be supplied in standard shapes or produced in custom formats to match specific sealing surfaces.

Natural rubber rubber gaskets (NR) specifications

Hardness: 35–70 Shore A
Density: 0.93–1.00 g/cm³
Tensile Strength: 15–25 MPa
Elongation at Break: 450–750 %
Temperature Range: −50 °C to +80 °C
Resistance: abrasion, water

 

Natural rubber provides excellent elasticity and abrasion resistance, but has poor resistance to oil, UV radiation and ozone.

Custom production

In addition to standard Natural rubber rubber gaskets (NR), we can CNC cut custom shapes and dimensions to your drawing. Suitable for prototypes, small series and repeat production.
