EPDM Rubber Seal D1.5 is a small round-profile rubber seal with a nominal diameter of 1.5 mm. It can be considered for applications requiring a compact rubber profile for gap filling, cushioning, positioning, or sealing support.
For a small profile such as D1.5, the diameter alone does not define the complete product specification. Installation gap, required compression, length, retention method, and operating environment should also be reviewed.
REP Vietnam provides consultation and custom EPDM rubber profile manufacturing based on physical samples, technical drawings, dimensions, required lengths, quantities, and application requirements.
An EPDM Rubber Seal D1.5 is a small round-profile rubber seal with a nominal diameter of approximately 1.5mm.
It may be considered for applications where a compact rubber element is required for gap filling, cushioning, positioning or sealing support.
Because this is a very small rubber profile, the D1.5 designation should not be treated as the complete product specification.
The actual installation gap, compression condition, required length, retention method and operating environment should also be confirmed.
Key considerations for EPDM rubber seal D1.5
EPDM is widely used for rubber seals and technical rubber profiles.
However, product suitability depends on both material and geometry.
When selecting a D1.5 rubber seal, customers should consider:
Material.
Cross-section.
Installation gap.
Compression.
Required length.
Installation method.
Contact surfaces.
Operating environment.
Required quantity.
For custom industrial applications, a physical sample or technical drawing is recommended whenever available.
Applications of a D1.5 EPDM rubber seal
Small Gap Filling
A small round rubber profile may be used to occupy a narrow gap between mating surfaces.
The actual installation gap should be confirmed before selecting the profile.
Cushioning
The rubber profile may provide an elastic layer between components where direct contact needs to be reduced.
Sealing Support
Depending on the mechanical design, a small EPDM profile may contribute to limiting the passage of dust, moisture or other environmental elements.
Actual sealing performance depends on the complete assembly rather than the diameter alone.
Why Should D1.5 Be Confirmed Before Production?
For very small rubber profiles, even a minor dimensional difference may affect assembly.
The term “D1.5” does not specify:
Required length.
Tolerance.
Installation gap.
Compression.
Retention method.
Contact geometry.
Operating conditions.
Therefore, a physical sample or technical drawing is highly recommended for replacement and custom-manufacturing applications.
Customers should not assume width, height or thickness from the D1.5 designation without a verified drawing or sample.
Round EPDM seal vs. Other rubber profiles
A round D1.5 profile is suitable for designs requiring a circular cross-section.
However, other applications may require U-profiles, D-profiles, L-profiles, H-profiles, T-profiles, rectangular profiles or custom cross-sections.
For example, a U-profile may be more suitable where the rubber needs to grip the edge of a panel or sit inside a retaining channel.
Therefore, profile selection should be based on the actual installation structure rather than simply choosing the closest-looking dimension.
Custom EPDM rubber seal manufacturing
Custom manufacturing can be useful when the required rubber seal is not available as a standard product.
This may apply when:
The original seal has no part number.
The existing seal needs to be replaced.
A special cross-section is required.
Standard profiles do not fit the assembly.
Specific cut lengths are required.
OEM production is required.
Customers can provide:
Physical sample.
Technical drawing.
Cross-section dimensions.
Required length.
Quantity.
Installation photos.
Operating conditions.
Special requirements.
For a small profile such as D1.5, providing a sample or drawing is particularly helpful.
EPDM or another rubber material?
EPDM is not automatically suitable for every rubber sealing application.
Material selection should be based on the actual operating environment and technical requirements.
Depending on the application, customers may also need to evaluate other materials such as NBR or silicone.
The correct material should therefore be selected according to the actual application rather than based only on product name or purchasing price.
Information required for ordering
For a quotation or custom-manufacturing request, customers should provide:
Product: EPDM Rubber Seal D1.5
Diameter/profile: Based on drawing or sample.
Length: Meter, coil or cut length.
Quantity: Required meters or pieces.
Application: Installation location and intended function.
Environment: Indoor, outdoor, moisture, heat or other conditions.
Reference: Sample, drawing or installation photo.
The more complete the information, the easier it is to confirm the correct profile before production.
Ordering process
Step 1 – Submit the Requirement
Send the product name and available dimensions.
Step 2 – Provide a Sample or Drawing
A sample or drawing is recommended for small custom profiles.
Step 3 – Confirm the Application
Provide installation and environmental information.
Step 4 – Discuss the Manufacturing Solution
REP reviews the profile, material and manufacturing requirements.
Step 5 – Quotation and Production
After the specification and quantity are confirmed, quotation and production can proceed.
The EPDM Rubber Seal D1.5 is a small round rubber profile with a nominal diameter of approximately 1.5mm. It may be considered for gap filling, cushioning and sealing-support applications where a compact cross-section is required.
Because the profile is small, the D1.5 designation should be verified against the actual sample or technical drawing. Installation gap, compression, required length and operating conditions should also be considered.
