O-rings direct from the manufacturer
KREMER - Your O-ring supplier especially for industry and trade
As a technical purchaser or decision-maker in industry, you know that the smooth operation of entire systems and processes can depend on a single seal - an O-ring, for example. Invisible but indispensable, O-rings keep your machines running, ensure quality and prevent things from getting stuck or coming to a standstill in production.
It is therefore clear that you expect more than just standard goods from your O-ring supplier. You want a partner at your side who understands your requirements, knows the technical context and has expertise in materials. Someone who speaks your language. This is exactly what you get from KREMER.
The ideal O-ring for every requirement
Depending on the medium, temperature and area of application, you need exactly the right material - otherwise the O-ring seal may fit, but its performance will not. This is exactly where KREMER's material expertise comes into play: We supply you with a wide selection of O-rings that hold what your specific application requires - chemically resistant, compliant with approvals, durable:
- EPDM-O-Rings - resistant to UV radiation, weather, hot water, vapour and glycol-based brake fluids
- O-Rings aus FFKM/Krevolast® - for extreme chemical loads in the chemical industry or refineries
- FPM/FKM O-Rings (Viton®) - for high-vacuum applications and the automotive industry as well as DVGW-approved O-rings (class E2) for gas appliance and gas system construction
- NBR-O-Rings - resistant to oil, grease and fuel; also available as HNBR O-rings for higher temperatures
- Silicone-O-Rings - heat and UV-resistant, FDA-compliant for food and pharmaceutical applications, wide temperature range
- Coated O-Rings - for low-friction assembly in automated processes
Advice and expertise - so that your O-ring application works optimally
O-rings only perform reliably when the operating conditions, installation situation and material behaviour interact perfectly. In many industries, there are also strict regulatory requirements - for example in the food, pharmaceutical and medical technology sectors.
But that's not all: is it about small or large diameters? O-rings in standardised sizes that we can supply directly from stock? Or special dimensions because the installation situation demands it? Do you need O-ring materials in standard shore hardnesses such as NBR70 or special approvals for use in the drinking water, food or pharmaceutical sectors, such as FDA-compliant O-rings or in accordance with DVGW, 3-A Sanitary Standard or USP Class VI?
We also consider issues such as friction and dynamics at an early stage: Coated O-rings, for example with environmentally friendly paints without solvents, reduce the static friction coefficient and minimise stick-slip behaviour. Ideal for automated processes and dynamic applications.
As you can see: There is no substitute for genuine consultation at eye level. Because the sooner we know your requirements when it comes to O-rings, the smoother your project will run - both technically and economically. At KREMER, you speak directly to experts who understand exactly what you need.
