Gaskets for portholes
Gimatech’s porthole gaskets are ideal for ensuring a secure seal between glass and sheet metal in various industrial applications. They offer versatile solutions with “H”, “Z”, and “U” designs, adapting to different mounting and protection needs against leaks.
These seals are designed for easy installation, with self-sealing models or additional sealing for enhanced protection. They are perfect for applications requiring reliable sealing in environments exposed to vibration or movement.
All products are manufactured according to European environmental regulations, ensuring compliance with REACH and RoHS standards. Contact us for more information or to request custom samples.
For porthole gasket, we mean all those profiles with load-bearing capacity, able to be positioned between glass and sheet metal.
They can be essentially of three types:
- self-sealing “H”, with a flap of the seal itself to be positioned in its seat after installation
- “H” with seal, to be positioned in its dedicated seat after installation
- “Z” without seal
- “U” seals see “U” seals section
