O-Ring Cords, Profile Cords

As well as O-Rings, O-Ring Cords also have a circular cross-section. They are often used to seal containers and tubes of large diameter, when there is no suitable O-Ring available.

We supply Profile Cords in different cross-sections (rectangular or according to customer specifications).

Preferred materials are NBR, FPM, EPDM, MVQ. Upon request we also supply special materials such as AF (Aflas®), CR, CSM (Hypalon®), EPDM peroxide, H-NBR, IIR, NK, PU, PVC, SBR, TPE, sponge rubber and more.

From now on the materials EPDM, FPM, NBR and MVQ are also available in FDA compliant mixtures. Additionally, we supply custom-made O-Ring Cords as well as Profile Cords made of NBR that resists low temperatures as low as – 45 ° C, or made of TPE, which complies the test method “UL 94”.

Previously it was only possible to supply O-Ring Cords with significantly larger tolerances than usual O-Rings. The ususal O-Ring Cords show tolerances according to the Standard ISO 3302-1 E2, or the slightly more restricted Standard ISO 3302-1 E1.

As of now, we supply custom-made O-Ring Cords with special tolerances according to the Standard ISO 3601-1 in cord sizes between 2.62 mm and 40.00 mm and made of the elastomer materials NBR, H-NBR, EPDM, MVQ and FPM.

Depending on the respective elastomer material and the cord thickness, O-Ring Cords are available in shore hardness between 40 Shore and 90 Shore.

The respective minimum order quantity depends on the cord diameter.

Using the example of an O-Ring Cord with a diameter of 5.00 mm, we would like to show you the different tolerances:

ISO 3302-1	E2 tolerance	5,00 +/- 0,50 mm
ISO 3302-1	E1 tolerance	5,00 +/- 0,35 mm
ISO 3601-1	tolerance	5,00 +/- 0,13 mm
