O-Rings − Vulcanised Joined Rings

O-Rings − Vulcanised Joined Rings

Whatever your requirements, industrial rubber specialist J-Flex can help with vulcanised joined cord rings (o-rings), that are ideal for sealing exterior lighting, security equipment, control boxes and filtration equipment. In fact any items that need to withstand the elements, wind, rain, cold weather, hot weather and more.

• Viton™ joined rings
• Silicone cord joined rings
• Nitrile rings
• EPDM rings
• Neoprene joined rings


Sponge materials are also available to fill uneven gaps and misalignments.

Vulcanised rings have no upper restrictions on inside diameter.

On larger joints we can achieve tight dimensional tolerances.

The minimum inside diameter limit is 100mm and cross section diameters range from 3mm to 30mm.

Whatever the size of O-ring / vulcanised joined ring you require, we can usually help.
