If you're buying O-rings online, you sometimes know the exact part number and quantity you need. At other times, you may just know certain attributes of the O-ring you need. For example, the dimensions must be 1.78 x 1.02 mm, or it should be made of silicone.

Or it could be that you need an O-ring suitable for use with drinking water processes or one that can tolerate contact with petroleum products.

At Freudenberg Sealing Technologies, we have an easy process for finding O-rings and ordering them online. Here's how you can find the right O-ring on our website and place your order with ease.

Finding the right O-rings

To buy O-rings online, you need a trade account, which you can apply for through our Trade Account Access page.

To find your O-ring, select from the ‘O-ring Kits’ dropdown menu found on each web page, or choose the ‘Seal Products’ dropdown menu and look in the O-ring category. O-rings are listed by material type, e.g. EPDM, silicone, nitrile.

Once you’ve found the O-ring, click on it, choose the quantity and proceed to the checkout.

If you’re not sure about the materials but have the dimensions of the seal you need, you can use the Seal Filter & Finder on the top right of the page. Once you have entered the dimensions, any matching products are displayed and you can make your choice.
 

Detailed O-ring information

If you need to know more about any O-ring, the Freudenberg E-Catalogue describes each one in great detail. The catalogue is searchable by O-ring type, dimensions, materials and/or Shore hardness.

Each O-ring has a material data sheet showing its physical properties (density, hardness, modulus) and its conformity to standards such as DIN, EC, AS/NZS, NSF and FDA. The data sheet also indicates the application for which the O-ring is suitable – food production, fuel lines or hydraulics, for example.
