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

We can manufacture custom bubble seals to suit your projects requirements. These sections are commonly used for sealing applications on doors, cabinets and windows. They are usually manufactured as a co-extrusion comprising of a solid foot and sponge sealing bulb but can also be extruded wholly from solid materials for applications that have large closing forces. We normally manufacture these profiles with a hollow centre to aid compression and create a reliable watertight seal.
Depending on your projects requirements, we are able to manufacture bubble seals with any size sealing bulb and foot. The bulb can be extruded as an O or D shape with a varying wall thickness depending on how soft and compressible it needs to be. We have the option to manufacture the holding foot as a T shape or arrow profile in any size to ensure it can be easily installed in the existing channel.
Our custom rubber profiles are made-to-order based on your projects requirements. Please contact us with your specification.
Material and Dimensions
Bubble 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: Gap
B: Internal Diameter
C: External Diameter
D: Neck Thickness
E: Foot Thickness
F: Foot Width
G: Material
H: Hardness or Density
I: 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.
Standard Bubble Seals
With an extensive range of standard profiles, our selection of bubble seals are available in a range of materials and sizes. The majority of these profiles are manufactured as a co-extrusion that comprises of a solid rubber foot with a sponge sealing bulb. They are all sold by the metre and are normally immediately available for dispatch on next working day couriers.
Sponge Seals
Although
our sponge sections differ in shape to traditional bubble seals, they can be
used for similar applications where you require a section with a solid rubber
foot and sponge sealing bulb.
Window and Door Seals
These profiles fit into a channel that securely holds the seal in place. They are all manufactured with a solid rubber foot but can be purchased with either a sponge or solid sealing bulb.
Window Gaskets
Our off the shelf glazing seals are commonly used for uPVC glazing systems and feature an arrow foot that pushes into the window channel to hold the seal firmly in place. We are also able to manufacture Custom Window Gaskets to replicate existing profiles.
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
