Oven Door Seals
High-temperature silicone oven door seals and gaskets manufactured in Worthing, West Sussex. Tadpole, P, e and D section profiles plus fully custom cross-sections — supplied in continuous lengths, cut to length, or vulcanised into joined rings made to your exact door size. For appliance OEMs, catering equipment builders, industrial oven manufacturers and replacement buyers alike.
Why Silicone Is the Material for Oven Door Seals
An oven door seal has one of the hardest jobs of any gasket. Every time the door opens, the seal goes from oven temperature to room temperature and back — often dozens of times a day in a commercial kitchen. Organic rubbers such as EPDM or Neoprene harden, crack and lose their spring above about 130°C. Silicone rubber (VMQ) shrugs off this thermal cycling: it stays flexible from -50°C right up to +200°C as standard, and up to +300°C in our high-temperature grade — enough for pyrolytic self-cleaning cycles and industrial process ovens.
Just as important is compression set resistance — a seal's ability to spring back after being squashed. Silicone's compression set is excellent even at elevated temperatures, so an extruded silicone oven door gasket keeps sealing tightly door-close after door-close, year after year. That means stable cooking temperatures, lower energy consumption, and no heat leaking onto control panels, hinges or worktops.
For catering and food-processing equipment, silicone is also available in food-safe grades compliant with FDA 21 CFR 177.2600 and EC 1935/2004 — something most organic rubbers cannot offer.
Viking Extrusions manufactures the complete oven door seal, in-house, in the UK: we extrude the profile from our own compound, cut it to length, and can vulcanise it into a continuous joined ring made precisely to your door dimensions — no corners to bodge, no joints to fail.
Oven Door Seal Profiles We Manufacture
Most oven doors use one of a handful of proven seal profiles. We extrude all of them from stock tooling — and if your door needs something different, we tool custom profiles from 5 working days. Click any profile to view specifications.
Not sure which profile your oven uses? Post us a short sample of the old seal — even a hardened, brittle one — and our engineers will identify the cross-section, match the material grade and quote a like-for-like replacement. All profiles are extruded to BS 3734-1 / ISO 3302-1 tolerance Class E3 as standard.
Silicone Grades for Oven Door Seals
We compound our own silicone in-house, so every oven door seal is extruded in the right grade for its duty — from domestic appliances to +300°C industrial process ovens.
- Continuous service to +300°C
- Excellent heat-ageing resistance
- Retains flexibility at extremes
- First choice for industrial oven seals
- FDA 21 CFR 177.2600
- EC 1935/2004 compliant
- Odourless and tasteless
- Steam and autoclave resistant
- Temperature: -50°C to +200°C
- Shore A 20 to 80
- Excellent compression set
- Any colour — RAL matched
For direct food contact and the most demanding hygiene requirements, our food-grade compounds are also available platinum-cured — offering lower volatiles and higher purity than standard peroxide-cured silicone. Read our guide to platinum vs peroxide cured silicone to see which is right for your equipment.
How to Measure and Replace an Oven Door Seal
A hardened, cracked or sagging door seal lets heat escape, lengthens cooking times and wastes energy. Replacing it is straightforward — here's how to get the measurements right first time.

Where Our Oven Door Seals Are Used
From a single replacement gasket to scheduled OEM production, the same UK-made extrusions seal ovens across every sector.

OEM Supply or One-Off Replacement — We Do Both
Whether you build ovens or maintain them, the same in-house extrusion, cutting and joining capability works for you.
For OEMs & Equipment Builders
If you manufacture domestic appliances, catering equipment or industrial ovens, we supply production quantities on schedule — continuous coils for your assembly line, pieces cut to length ready to fit, or fully joined door-seal rings delivered as a finished component. Our engineers will review your door design, recommend the right profile geometry, hardness and grade for the closure force and temperature involved, and produce bespoke tooling from 5 working days. Because we compound, extrude, cut and join everything in-house at our Worthing factory, you get one accountable UK supplier, full batch traceability to ISO 9001, and the ability to iterate a profile design quickly during prototyping — starting from just 10 metres.
For Replacement & Maintenance Buyers
Oven out of production, or the OEM spare discontinued? You don't need a part number — you need the profile matched. Post us a short section of your old seal (even hardened or cracked) and we'll identify the cross-section, match the silicone grade and quote a like-for-like replacement, supplied as a cut length or a joined ring vulcanised to your door dimensions. This is how facilities teams keep older commercial catering ovens, laboratory ovens, autoclaves and process ovens in service for years after spares disappear. Typical replacement orders are small — our 10-metre minimum keeps a single-oven repair affordable, and multiple doors can share one order.
A UK Manufacturer, Not a Reseller
Every oven door seal we sell is extruded, cured, cut and joined at our own factory in Worthing — which is why we can match obsolete profiles and hold tight tolerances.
