JIS 10K DN80 Custom 250mm Marine Rubber Compensator - Double Sphere Flexible Joint with Rubber Encapsulated Flanges | Alternative to Trelleborg|Rubberflexjoint

This custom DN80 rubber expansion joint is designed as a direct 1:1 interchange for Trelleborg marine bellows in JIS 10K piping layouts. Featuring a specified 250mm face-to-face length, the twin-sphere EPDM body delivers twice the axial movement and angular deflection of standard single-sphere joints, minimizing pipeline stress under hull vibrations.

Unlike standard turn-up rubber faces, this unit utilizes a full-rubber encapsulation process. The EPDM compound completely covers the sealing face and the outer edges of the galvanized carbon steel flanges through high-pressure vulcanization. This continuous rubber shield ensures zero metal-to-fluid contact, eliminating galvanic corrosion in saltwater systems and preventing gasket bypass under constant engine harmonics. This interchangeable rubber flexible joint helps shipyards avoid long European lead times during urgent dry-dock overhauls. We specialize in custom-to-drawing manufacturing to deliver exact soft-connection solutions based on your CAD files.
