At Nufox Rubber, we don't just manufacture rubber extrusions; we help you solve your unique engineering, design, and performance challenges.
Based in Manchester, UK, we are an industry-leading manufacturer with over 30 years of experience supplying premium, custom rubber extrusions to a wide range of industries.
Our expertise covers everything from standard sealing strips to complex custom solutions. We work closely with your engineering team to design and manufacture rubber extrusions tailored to your precise application requirements.
We provide end-to-end custom extrusion die-cutting, creative problem-solving, and access to an extensive selection of rubber extrusion profiles, ensuring you find the right fit for your needs.
Your satisfaction and success are at the forefront of what we do.
Custom Rubber Extrusion Capabilities
The capabilities of our rubber extrusions are supported by an extensive range of advanced materials and state-of-the-art technologies designed to meet your requirements and optimise product performance.
- Vibration Dampening & Shock Absorption: Our solid and closed-cell sponge rubber components are engineered to absorb heavy impacts, dampen operational noise, and minimise industrial wear and tear.
- Advanced Weather & Environmental Sealing: We design custom weatherproof seals and specialised geometric rubber profiles (P, U, and L seals) that completely block out water, dust, and air.
- Dual-Durometer Co-Extrusion: Our advanced dual-durometer capabilities allow us to fuse materials of varying hardness into a single, cohesive rubber profile.
- Specialist Finishes: We enhance usability with high-performance add-ons, including low-friction self-lubricating silicone, conductive formulations for vital EMI shielding in electronics, chemical-resistant fluoroelastomers, and pressure-sensitive self-adhesive backings.
- Decorative Trim: We combine form and function with options like colour matching for aesthetic alignment.
We understand precision is paramount; our high-quality, advanced rubber mouldings perfectly complement our extrusions, providing you with a complete product solution.
Custom Rubber Extrusions for all Industries
We engineer high-performance rubber extrusions tailored to your industry's specific needs. Here are some examples.
- Rail & Coach: Window and door glazing seals, protective rubber profiles, weatherstripping, and interior decorative trim designed to comply with industry safety standards.
- Automotive: Body seals, chassis buffers, U-channel edge trims for body panels, glass run channels, and durable flexible tubing for fluid and gas transfer systems.
- Construction & Infrastructure: Heavy-duty structural glazing gaskets, door and window weather seals to prevent energy loss, weighbridge rubber, and rugged brick-grab profiles for materials handling.
- Marine & Defence: Complex, bespoke rubber profiles engineered from specialised compounds to withstand extreme environments, saltwater exposure, ozone degradation, and strict defence specifications.
- Industrial Engineering & Manufacturing: High-pressure O-rings, pneumatic/hydraulic gaskets, and impact-absorbing buffers that keep heavy machinery operating safely and smoothly.
- Cleanrooms & Laboratories: Specialised inflatable seals designed for autoclaves, airtight laboratory doors, and processing equipment requiring dynamic, high-integrity containment.
Seals & Weatherstripping
Components such as P-seals, L-extrusions, D-sections, and specialised tadpole rubber profiles are designed for peak environmental protection and provide impenetrable barriers against air, water, and dust in doors, windows, and enclosures. Our tadpole seals are engineered to handle high-temperature insulation for industrial ovens and furnace doors.
Edge Protection & Glazing
Our U-channels, square-U sections, T-profiles, and angle rubber extrusions provide reliable panel retention and hold glass, sheet metal, or acrylic panels securely in place while shielding operators from sharp edges.
Impact & Vibration Control
We help protect your equipment and machinery with our heavy-duty rubber buffers, solid cords, and custom shock blocks, which absorb high-impact shocks, dampen structural vibrations, reduce mechanical wear, and significantly improve operational safety.
Fluid & Gas Management
Our flexible rubber tubing and hollow sections are widely used for transfer systems and reliably moving liquids and gases through industrial, automotive, and mechanical machinery without risk of material degradation or pressure loss.
High-Pressure Sealing
We manufacture high-integrity O-rings, die-cut gaskets, and inflatable seals designed for absolute leak prevention. These products secure joints under pressure in hydraulic, pneumatic, and plumbing infrastructure, while our inflatable variants provide active, expandable sealing for dynamic closures.
Surface Protection & Matting
Our industrial rubber sheets, continuous strips, and wide matting provide durable, anti-slip surfaces and structural protection in high-traffic environments. These materials also offer excellent insulation and serve as a robust base stock for bespoke gaskets.
Popular Rubber Extrusions
Profiles: P, L, D-Sections
Versatile profiles for sealing, cushioning, and edge protection in applications such as doors, windows, and industrial equipment, with P-sections commonly used for tight seals, L-sections for corner edging, and D-sections for impact cushioning.
U-Channels
U-channels to provide edge protection and hold panels, glass, or metal securely in place in automotive, construction, and industrial applications.
Rubber Sheets & Matting
Rubber sheets and matting for flooring, anti-slip surfaces, and industrial gaskets, providing protection, insulation, and durability in high-traffic or heavy-duty environments.
Gaskets
Rubber gaskets for sealing joints between components, preventing leaks and contamination in industries like plumbing, automotive, and manufacturing.
Rubber Strips & Weatherstripping
Rubber strips and weatherstrips to insulate doors and windows, reducing energy loss, preventing drafts, and providing noise and weatherproofing.
Rubber Tubing
Rubber tubing widely used for fluid and gas transfer in medical, industrial, and automotive systems, offering flexibility and durability.
Rubber Buffers
Rubber buffers to absorb impact and reduce vibration in machinery, vehicles, and structural applications, protecting equipment and improving operational safety.
Rubber O-Rings
Circular seals used to prevent leaks in hydraulic, pneumatic, and industrial systems, offering reliable sealing under pressure.

Frequently Asked Questions
What is Rubber Extrusion?
Rubber extrusion is a manufacturing process used to create continuous shapes with consistent cross-sections. The shape of the nozzle on the extruder determines the shape of the extrusion that is produced.
Raw, uncured rubber is forced through a shaped metal plate called a die. The extrusion process produces many everyday items, such as:
- Door and window seals (weatherstripping)
- Hoses and tubing
- O-rings and gaskets
- Tyre treads
Extrusion is efficient; it allows for high-volume production of complex profiles that would be nearly impossible to mould individually.
How Does a Rubber Extruder Machine Work?
A rubber extruder is a mechanical system that uses heat and pressure to transform solid rubber into a specific shape. The extrusion process generally follows these steps:
- Feeding (The Hopper) We feed cold, firm chunks or strips of raw rubber into the machine’s hopper, which is the entry point at the start of the line. It is a large, funnel-shaped metal bin positioned above the extruder machine.
- Churning & Heating (The Screw & Barrel) A massive, rotating screw pushes the rubber through a heated barrel. The intense friction and mechanical pressure melt the rubber down, turning it into a soft, pliable, dough-like state.
- Shaping (The Die) The screw forces the softened rubber through a custom-engineered opening called a die. This is the stencil that gives the rubber its final profile, whether that's a simple hose, a complex "D" shape for a car door seal, or a custom window gasket.
- Baking (Vulcanisation) When the rubber exits the die, it's still too soft to hold its shape for long. To fix this, it immediately passes through a high-heat curing tunnel (using microwaves, hot air, or molten salt). This "bakes" the rubber, triggering a chemical reaction that makes it strong, bouncy, and durable.
- Cooling & Cutting Finally, the hot, cured profile is run through a water-cooling tank to lock in its final dimensions. From there, we either coil it onto large reels or chop it into precise lengths, ready for delivery.
