O-rings, washers, gaskets and sealing rings.
Precision sealing
Precision rubber seals built around tolerance, medium and service life.
PRESIS develops O-rings, turned seals, washers and custom rubber gaskets for industrial equipment, export projects and maintenance supply.
Buyer pain points
Rubber sealing projects fail when drawing fit, medium and hardness are not aligned.
- Small dimensional shifts can change assembly force and leakage behavior.
- Oil, fuel, heat or chemicals affect material life and compression set.
- Customers often need the same drawing to work in multiple regions or equipment lines.
- Batch control and material source are as important as the geometry.
PRESIS solution
Precision rubber route
We review the drawing, medium and service conditions first, then align the seal geometry and compound route to the actual use case.
The aim is a stable rubber part that can survive the working environment without forcing the customer to rework the interface.
Material and process
Choose the rubber family according to medium, temperature and cycle requirement.
| Project need | Recommended route | Buyer questions to prepare |
|---|---|---|
| Oil-resistant seals | NBR or HNBR-style performance route for oil and fuel exposure. | Oil type, temperature, hardness, swelling limit and service life. |
| Higher heat / chemical seals | FKM or FFKM for demanding environment and longer stability. | Chemical medium, continuous temperature and budget target. |
| Weather and outdoor parts | EPDM, CR, BIIR or ACM for weathering and system fit. | Ozone, weathering, pressure cycles and installation method. |
