Cut from sheet
Solid or sponge silicone and rubber sheet, cut to profile.
Gaskets and seals · Flat gaskets
Flat gaskets.
Enclosure lids, flanges, pump covers, lighting housings. Flat gaskets do a lot of quiet work, and the right way to make one depends mostly on how many you need.
The detail
Moulded or cut?
At low volumes, cutting from sheet — by knife, die or water jet — needs little or no tooling and handles design changes easily. At higher volumes, a moulded gasket usually wins: less waste, moulded-in features like beads and locating pegs, and consistent thickness.
We make both, and we'll show you where the crossover sits for your part. Many programmes start cut and move to moulded once the design is settled.

Questions
What people usually ask.
Can a cut gasket seal as well as a moulded one?
For many enclosures, yes. Moulded gaskets add features that improve sealing on less stiff housings.
Do you do sponge gaskets?
Yes, for low closing force applications. Sponge is usually cut from sheet or extruded.
