Materials & quality
The right compound, verified before it ships
Material choice decides whether a seal lasts a season or a decade. We select compounds against your media, temperature and load — then verify every batch.

Indicative service ranges. Final selection depends on media concentration, pressure and duty cycle.
| Material | Service temperature | Hardness | Typical use |
|---|---|---|---|
| NBR / Nitrile | -30 to 100 °C | 40 – 90 Shore A | Oil, fuel and hydraulic media |
| EPDM | -40 to 130 °C | 45 – 80 Shore A | Water, steam, weathering and ozone |
| Silicone | -55 to 200 °C | 30 – 80 Shore A | High-temperature and food-safe duty |
| Neoprene / CR | -30 to 110 °C | 40 – 80 Shore A | Flame-retardant sealing, gaskets |
| Natural Rubber | -40 to 80 °C | 35 – 75 Shore A | High resilience and abrasion |
| Viton / FKM | -20 to 210 °C | 60 – 90 Shore A | Aggressive chemicals and heat |
Quality assurance
Checks built into the line
Inspection is not a final gate only — it runs alongside production.
- Incoming compound verification against specification
- Preform weight control for consistent cavity fill
- Cure time and temperature logged per batch
- Dimensional checks with calipers and gauges
- Hardness verification using calibrated durometers
- Bond adhesion checks on rubber-to-metal parts
- Visual inspection for flash, porosity and finish
- Batch traceability from compound lot to dispatch
