O-Rings of large diameters
Attention:  MOLDED, NOT GLUED !

Today there are no limits to the compression molding of large diameters O-Rings,
in fact, thanks to an innovative system of equipments and molds, managed by
a specially designed software, can be achieved infinite measures starting
from a minimum of 200 mm. So there are no costs to build molds.
It ensured compliance with the O-Rings tolerances ISO 3601-1

The cords currently available are the following:

2,62 3,00 3,53 4,00 4,50 5,00 5,33
5,50 5,70 6,00 6,35 6,50 7,00 7,50
8,00 8,40 8,50 9,00 9,50 10,00 10,82
11,00 12,00 12,70 13,00 14,00 14,40 15,00
16,00 18,00 20,00 22,00 24,00 26,00 mm

There aren't minimum lots to buy, we can provide  just one piece.

The compounds currently available are:

ASTM

HNBR Black 60 90 Oil, gas, acids, alcohols, oxidation, usury, AED

However we are being tested other special compounds, 
and new ones can be made on your specification.

 

 MOLDED CORDS 

For all the cords above, we can provide the CORD MOLDED (not extruded)
in the various compounds and related hardnesses, in rolls of variable length from 12 to 60 meters, depending on the diameter cord.
Please note that we also have cords in compounds HNBR-FKM 90 AED (Anti-Explosive Decompression - valves sector)
Minimum order: 1 roll

Surface finish: the cord molded (compression), would have
the witness of "mold closing" but is "grinded" according
to the tolerances ISO 3601-1:2008
