Products I ISC O-Rings and Static Seals
Cord
The endless, extruded cord with O-ring profile serves as
base material for cord rings, among others. These are
used, for example, for the sealing of larger flanges or
tank lids.
Range
By the metre:
From 1 to 40 mm cord diameter available
Cord sections:
Produced from cord supplied by the metre
From 1 to 40 mm cord diameter
Up to 2000 mm length without integral bend
possible.
Cord rings
Cord rings are extruded cords, which are cut to the ap-
propriate diameter and bonded or vulcanised to butt.
Range
Cord rings are produced from cord supplied by the me-
tre. They are available with a cord diameter from 1 to
40 mm. A two-part adhesive can be used for bonding
to butt. NBR and FKM product versions are available
ex works with vulcanisation to butt.
Tolerances
The range of tolerances tends towards the negative
side as a certain amount of elongation of rings with a
large diameter is possible at any time during installation
without causing an appreciable tapering of the cross
section.
Hose rings
Hose rings are rings punched from the hose and pro-
duced as hose by the metre. Hose rings made from
precision hoses have absolute sharp inside and outside
edges. The inside diameter is smooth and absolutely
cylindrical. If necessary, a chamber and/or coloured
marking is also possible.
Due to the special manufacturing pro cess, a particularly
good compression set is achieved.
Range
Hose rings are available always in agreement/on
enquiry with a wall strength from 1 mm and up to an
inside diameter of 200 mm.
