Rubber Blocks
Solid blocks of rubber manufactured to your dimensions in Worthing, West Sussex — anti-vibration mounts, buffers, machine feet, packing and spacer blocks in silicone, EPDM, nitrile, neoprene, FKM and natural rubber. From a single block to production quantities.
One Simple Shape, Dozens of Jobs
A solid rubber block is engineering's quiet workhorse — absorbing shock, isolating vibration, spreading load and protecting whatever it sits between.
Solid Rubber Blocks, Made to Your Dimensions
Viking Extrusions manufactures custom rubber blocks at our factory in Worthing, West Sussex — established 1991. Send a drawing, a sketch with dimensions, or even a worn sample, and we will produce blocks of rubber in the right material and hardness for the job, from a one-off replacement to scheduled production quantities.
Most blocks are made by compression moulding — solid sections cure uniformly in a heated tool, and tooling for simple block geometry is the most economical in moulding. Thin blocks and pads can instead be cut from cured silicone rubber sheet, and we quote whichever route is cheaper for your size and quantity.
Every batch is manufactured to ISO 9001 disciplines with full material traceability. Dimensions follow ISO 3302-1 Class M3 as standard, with tighter classes available on a case-by-case basis after engineering review.

Rubber Block Materials Compared
Typical working ranges — exact figures depend on the specific compound and grade.
| Material | Typical Hardness | Typical Temp Range | Best For |
|---|---|---|---|
| Natural Rubber (NR) | Shore A 40–80 | -50°C to +80°C | Anti-vibration mounts, impact pads, fenders |
| EPDM | Shore A 40–85 | -40°C to +130°C | Outdoor blocks, weather-exposed pads |
| Nitrile (NBR) | Shore A 40–90 | -30°C to +100°C | Blocks near oils, fuels and greases |
| Neoprene (CR) | Shore A 40–85 | -35°C to +110°C | General engineering, marine, moderate oil |
| Silicone (VMQ) | Shore A 30–80 | -50°C to +200°C | Temperature extremes, food contact, hygiene |
| FKM / Viton® | Shore A 60–90 | -20°C to +200°C | Aggressive chemicals, fuels at temperature |
Rule of thumb on hardness: choose the softest block that carries your load without excessive deflection — softer isolates vibration better, harder carries more weight.
