How to Choose the Right Rubber Strips for Your Project
Rubber strips are used across countless UK industries — construction, automotive, marine, HVAC, manufacturing, electronics, and even home DIY. Yet despite being such a simple component, choosing the wrong type of rubber can lead to early degradation, poor sealing, leaks, or chemical failure. Picking the right rubber strip ensures durability, safety, and long-term performance.
This comprehensive guide walks you through the different types of rubber strips available, how each performs under UK conditions, what to look for in terms of hardness and thickness, and how to match each product to your exact application. Whether you need something UV-resistant for outdoor use, sponge-soft for cushioning, or chemical-proof for industrial environments, this guide will help you make the right choice.
What Are Rubber Strips Used For?
Rubber strips are extremely versatile and can be used for:
-
Weather sealing around windows, doors, sheds, caravans, and marine hatches
-
Gasket creation for plumbing, HVAC, machinery, and electrical enclosures
-
Noise and vibration damping
-
Thermal and draught insulation
-
Edge protection on sheet metal, panels, and furniture
-
Impact reduction
-
Food-safe sealing (silicone products)
-
Fuel and chemical exposure (Viton products)
Each application demands a specific rubber type, so understanding the properties of each material is essential.
Types of Rubber Strips (By Material & Purpose)
Below you’ll find a full explanation of each rubber strip available in the range — rewritten, expanded, and optimised around your products.
Solid Neoprene Rubber Strip 5m Long (General Purpose Solid Rubber)
Specification:
Solid Neoprene Rubber Strip, 5m Long × 50mm Wide (various thicknesses available)
Hardness: 65 Shore A
Temperature Range: –20°C to +90°C
This neoprene strip is an excellent all-rounder for weather sealing and general sealing applications where durability matters. Resistant to water, oil, grease, UV light, and fuel, it’s perfect for environments that need a reliable, commercial-quality seal. Its medium-firm hardness (65 Shore A) delivers long-lasting structure while still providing enough flexibility to adapt to uneven surfaces.
Best for:
General sealing, oil-resistant gaskets, outdoor weatherproofing, workshop use, vehicle seals.

EPDM/CR blend, DA320 closed-cell sponge
Hardness: 43 Shore A
Temperature Range: –40°C to +70°C
Adhesive: Yes (one side, with yellow removable backing)
This compressible sponge strip provides a soft, cushioned seal ideal for vibration damping, sound reduction, and irregular surfaces. Its closed-cell structure ensures waterproof performance, while the self-adhesive backing allows quick, clean installation.
It’s commonly used in:
-
Caravan and boat sealing
-
Vehicle doors and boots
-
Vacuum press systems
-
Smoke sealing

Expanded Neoprene Sponge Strip (Non-Adhesive)
Specification:
10m Long × 25mm Wide (various thicknesses available)
Temperature Range: –40°C to +70°C
Hardness: Soft, closed-cell
This sponge strip offers the same soft compression feel as the adhesive version but is delivered without adhesive, making it suitable for bespoke installations, mechanical fixing, or uses where adhesive cannot withstand the environment.
Waterproof, UV-resistant, and acid-resistant, it’s perfect for external sealing and acoustic damping.
Solid Neoprene Rubber Strip – Self Adhesive (Pack of 2)
Specification:
2 × 2.5m Strips, 1.5mm Thick (choice of widths)
Hardness: 65 Shore A

Automotive, catering (food containers/seals), construction, lighting, HVAC, marine, energy systems, electronics.
Premium Rubber Strip 75 Hardness (Viton®)
Specification:
Genuine Black Viton® (FKM), 70–75° Shore A
Chemical Resistance: Outstanding
Temperature Tolerance: Extremely high
Viton® rubber is the top choice for harsh industrial environments where exposure to acids, oils, fuels, steam, and high temperatures is unavoidable. Its resistance to atmospheric ageing and chemical attack makes it unmatched for premium sealing applications.
Best for:
Aerospace, chemical plants, fuel systems, high-heat machinery.
Self Adhesive Backed HT800 Expanded Grey Silicone Rubber Strip
Specification:
3m × 10mm
Type: Medium-firm foam silicone

Home sealing, window and door draught-proofing, outdoor applications.
EPDM Rubber Strip Black
Specification:
Solid EPDM, 60 Duro (medium grade)
Length: 5m
Hardness: 65/70 Shore A
Chemical/UV Resistance: Exceptional
EPDM is one of the most weather-resistant rubber materials available. It resists sunlight, ozone, temperature cycling, and moisture better than most other elastomers, making it ideal for glazing, roofing, pipe seals, gaskets, and outdoor sealing.
How to Choose the Right Rubber Strip for Your Application
Selecting the correct rubber strip depends on several factors. Below are the most important things to consider.
Environmental Exposure
Different environments demand different materials:
| Environment / Exposure | Best Strip Types |
|---|---|
| Constant sunlight / outdoor UV | EPDM, White Silicone, SIL16 |
| Exposure to oils/grease | Solid Neoprene (both types) |
| Extreme weather + hygiene | White Silicone Weathering Strip |
| Harsh chemicals / fuels | Viton® Premium Strip |
| Vibration damping | Expanded Neoprene Sponge |
| High-temperature sealing | Silicone, Viton® |
| Acoustic dampening | Neoprene Sponge (Self-adhesive or Non-adhesive) |
Softness and Hardness (Shore Rating)
Understanding hardness is essential:
-
43 Shore A → Soft, compressible (sponge neoprene)
-
60–70 Shore A → Medium firmness (EPDM)
-
65 Shore A → Standard solid neoprene hardness
-
70–75 Shore A → Very firm, industrial-grade (Viton®)
Soft sponge is best for vibration/noise damping and irregular surfaces; solid grades provide structural strength for seals and edging.
