Custom Rubber Tadpole Seals

Manufactured to order from sponge and solid materials in a selection of sizes, colours and hardnesses.

Looking for an off-the-shelf product? View our extensive range of rubber tadpole seals available for next working day delivery. 

We can manufacture custom rubber tadpole seals in a selection of rubber and PVC compounds. The simplistic shape of this profile allows this section to be used for sealing hatches and doors, as well as beading between the wing and body on various older vehicles and classic cars. We normally manufacture these profiles with a hollow centre to aid compression but they can also be extruded as solid sections.

Depending on your projects requirements, we are able to manufacture a custom extrusion with any diameter bulb, flange length and wall thickness. This allows us to manufacture a bespoke seal with a bulb that will compress around 30% when the hatch or door is closed. The flange (otherwise known as the tail) can also be extruded in any length so that there is a sufficiently large area to bond or mechanically fix the tadpole section onto the required surface.

Our custom rubber profiles are made-to-order based on your projects requirements. Please contact us with your specifications.

Material and Dimensions  

Rubber tadpole seals are available from an extensive range of off-the-shelf products, but can also be manufactured to order to suit your projects requirements. To enable us to look at standard or custom profiles, we require the following information.

A: Wall Thickness
B: Flange Length
C: External Bulb Diameter
D: Internal Bulb Diameter
E: Material
F: Hardness or Density
G: Number of Metres

Our Custom Rubber Seal Manufacturing Process 

We work with a large range of rubber and plastic compounds including EPDM, Natural rubber, Neoprene, Nitrile, Silicone and PVC, many of which are available in either sponge or solid forms. This selection allows us to extrude a profile taking into account any environmental, chemical or temperature demands.

The manufacturing process starts with our specialist toolmakers who turn your sample or technical dimensioned drawing into a tool that can be used to extrude an exact replica of your rubber seal. This extrusion process uses temperature and pressure to push your chosen rubber compound through the tool to extrude the required shape. The extruded seal is then cured using heat to vulcanise and harden the extrusion.

Although the majority of rubber seals are manufactured using a very similar procedure, we understand that your sealing solution may require additional non-standard processes. This could include joining, applying self-adhesive backing, or cutting to desired lengths. Whilst it is possible to do this on-site after production, it is often preferable to do this at the time of manufacture to increase the speed and ease of installation of the final product.

Manufacturing a custom rubber seal can be completed at a relatively low cost with production runs requiring as little as 30 metres. For large production quantities, we have the option of manufacturing sample lengths before going to bulk production. This allows you to look at the finished product and test how it performs. The process of moving from concept to delivery can normally be fulfilled within two to three weeks, depending on the material and complexity of the profile.

Seal Design Service

Our CAD facilities allow us to work with you in designing the best sealing solution for your project. If your sealing requirements cannot be met by a standard section and you do not have a sample or technical dimensioned drawing, our Design Engineers can design a custom solution to your requirements.

Data Sheets

Standard Rubber Tadpole Seals

The majority of our standard products are sold by the metre and are normally available for dispatch on a next working day courier from our Hampshire based warehouse. Our off-the-shelf rubber and PVC tadpole sections are available in a range of sizes and materials.

Rubber Tadpole Sections

Our selection of off-the-shelf rubber tadpole seals are manufactured from EPDM and can be purchased in several different sizes. Depending on the size of the section, each profile has a different diameter bulb and flange length. 

Plastic Wing Piping

Plastic wing piping is manufactured from PVC and used between the wing and body on various older cars and other vehicles to create a neat sealed joint. This section is available in four different sizes to suit different vehicles.  

Other Custom Rubber Seals

Custom rubber seals can be extruded in virtually any shape in most rubber compounds. Different profiles are suitable for different applications and selecting the correct shape, material and hardness is essential to ensure a long term sealing solution. Visit our  Custom Rubber Seal directory to view our range of made-to-order extrusion shapes, gaskets and custom products.
