Browse our catalog of compression seal and fiber optic fittings that offer secure connections between cables. Compression seal fittings, also known as sealing glands, are used to seal elements that pass through either an environmental or pressure boundary. To create the seal, compression seal fittings use mechanical components and an axial force to compress a soft sealant that is within a body. This allows for ease of installation, adjustment, and replacement of the elements. For fiber optic fittings, connectors are spring-loaded, so the fiber faces are pressed together when connected. If you need any assistance in finding the right compression seal and fiber optic fittings for your needs, contact our team of experts at Electro-Meters today.
