Joined gaskets and spliced seals

Exonel cuts extruded profile to length and vulcanises the joints into endless gaskets, frames and rings. For large enclosures, panels and housings this is the practical alternative to a moulded seal.

FAQ

Common questions

What is a joined or spliced gasket?
An extruded rubber profile cut to length and joined end to end, usually by vulcanising, to make a continuous frame or ring.
When would I choose joined over moulded?
For large or unusual perimeters and lower volumes. Joining extruded profile avoids the cost of a large mould.
Which material suits an outdoor enclosure?
EPDM for weather, ozone and UV. Silicone where the temperature range is wider.

Need an endless gasket or frame?
