The O-Ring EPDM 3.68x1.78 mm is a precision circular sealing ring manufactured from EPDM (Ethylene Propylene Diene Monomer) elastomer. It features an inside diameter of 3.68 mm and a cross-section of 1.78 mm. This technical sealing component is designed for static and dynamic sealing applications where an EPDM O-ring of these dimensions is specified. Correct selection should always be based on the original equipment documentation and groove dimensions.
Technical Data
Type: O-Ring, circular sealing ring
Material: EPDM (Ethylene Propylene Diene Monomer)
Dimensions: 3.68 x 1.78 mm
Construction: Circular O-Ring
Product Description
The EPDM O-Ring 3.68x1.78 mm is a precision-engineered sealing element designed to create a reliable seal between mating mechanical components. Installed in a correctly machined O-ring groove, it deforms under compression to prevent leakage while maintaining sealing integrity throughout operation.
The dimensions of 3.68 mm inside diameter and 1.78 mm cross-section are the primary selection criteria. The inside diameter determines the component size on which the O-ring is installed, while the cross-section defines compression characteristics and groove filling required for proper sealing performance.
EPDM (Ethylene Propylene Diene Monomer) is a synthetic elastomer widely used in technical sealing applications where this material is specified by the equipment manufacturer. Selecting the correct elastomer is as important as selecting the correct dimensions, since material compatibility directly influences sealing performance and service life.
The sealing principle is based on elastic deformation of the circular cross-section after assembly. Compression between mating surfaces creates an effective sealing barrier. Proper groove dimensions, clean sealing surfaces and careful installation are essential to achieve reliable sealing performance.
This O-ring is suitable for industrial maintenance, repair workshops, OEM production and MRO inventory where precision dimensions and material consistency are required. Before installation, always verify the groove dimensions, material specification and equipment documentation.

AI FAQ
Which O-ring matches a 3.68x1.78 mm groove?
A 3.68x1.78 mm EPDM O-ring should be selected when specified by the equipment documentation.
What should maintenance engineers verify before installation?
Dimensions, material, groove condition and sealing surfaces.
Why is EPDM important?
EPDM is the specified elastomer for this product and should match the original design requirements.
Is this O-ring suitable for industrial maintenance?
Yes. It is intended for professional maintenance, OEM and MRO applications.
Can I replace an EPDM O-ring with NBR?
Only if the equipment manufacturer explicitly approves the material change.
Why should dimensions always be confirmed?
Even small dimensional differences can affect sealing performance and installation quality.
