Product Description
The Rubber Company supplies high-quality rubber Omega profile seals designed to provide reliable compression sealing for doors, windows, enclosures and flat-panel applications. Featuring a distinctive Omega-shaped cross-section, these flexible rubber seals combine the secure positioning of a T-shaped profile with the compression characteristics of a hollow bulb seal.
The unique design enables the hollow bulb to compress evenly under pressure, creating a tight, consistent seal against water, dust, draughts and other environmental contaminants. Unlike some conventional D-shaped rubber seals, Omega profiles are designed to compress with reduced lateral deflection, helping maintain effective sealing contact across the joint.
Our Omega rubber seals are suitable for a wide variety of industrial, commercial and architectural applications, including electrical enclosures, industrial doors, glazing systems and weatherproof panels. The flexible profile accommodates movement and variations in joint dimensions while maintaining sealing performance.
We offer Omega sealing profiles in a range of standard sizes and configurations, with material options including EPDM and silicone rubber to suit different operating environments. We can also manufacture bespoke rubber Omega profiles to your exact dimensions, subject to tooling costs and minimum order quantities.
Rubber Omega Seal Materials
EPDM Rubber Omega Seals
EPDM rubber offers excellent resistance to weathering, UV exposure, ozone and moisture, making it particularly suitable for outdoor sealing applications. EPDM Omega profiles are commonly used for industrial doors, architectural glazing, electrical enclosures and general weatherproofing.
Silicone Rubber Omega Seals
Silicone Omega profiles provide excellent flexibility and resistance to high and low temperatures. They are particularly suitable for applications involving thermal cycling, industrial ovens, specialist equipment and environments where consistent compression performance is essential.
Certain silicone grades may also be suitable for food-contact or hygienic applications, subject to the relevant material certification.
Bespoke Rubber Omega Profiles
At The Rubber Company, we understand that standard sealing profiles may not always meet the requirements of specialist applications.
We can manufacture custom Omega rubber extrusions to suit specific dimensions, compression requirements and installation methods. Our team can assist with material selection, profile design and manufacturing considerations to help identify an effective sealing solution.
Whether you require an existing Omega seal to be matched or a completely new profile developed, we can work from technical drawings, dimensions or physical samples.

FAQs
An Omega profile seal is an extruded rubber sealing component with a cross-section resembling the Greek letter Omega (Ω). Its flexible bulb compresses against a mating surface to create an effective seal.
Both profiles provide compression sealing. However, Omega seals feature a distinctive bulb and base configuration designed to promote controlled compression and help reduce sideways deflection in suitable installations.
EPDM is generally preferred for outdoor weatherproofing, while silicone is often selected for applications involving extreme temperatures. The most suitable material depends on operating conditions, chemical exposure and compression requirements.
Yes. We can supply bespoke Omega profiles manufactured to your dimensions and application requirements, subject to tooling costs and minimum order quantities.
Yes. Rubber Omega profiles can provide environmental sealing around electrical cabinets and enclosures. Where a specific ingress protection rating is required, the complete enclosure assembly must be appropriately designed and tested.
