Seal gasket for 1" fire hose coupling GEKO CG70001A, replacement gasket

Replacement seal gasket designed for 1" fire hose coupling by GEKO. This gasket fits 1-inch couplings and provides a resilient sealing element intended to restore or maintain a water-tight connection between hose sections and coupling components used in firefighting, training exercises, and industrial water-transfer tasks. The component is intended as a direct replacement part compatible with standard 1" coupling geometries.

Advantages

The gasket is made from a flexible, durable elastomer that resists compression set and provides reliable sealing under pressure. Its simple shape and standard dimensions enable quick replacement during routine maintenance or emergency repairs. The part is lightweight and compact, allowing easy storage as a spare on fire apparatus or in maintenance kits.

Suitable for

• Repair and maintenance of 1" fire hose couplings
• Field replacement during firefighting operations and training
• Industrial water-transfer hose connections requiring leak-free joints
• Equipment servicing where standard 1" coupling seals are worn or damaged

Key specifications

• Intended coupling size: 1 inch (nominal)
• Material: resilient elastomer suitable for water use
• Shape: circular gasket designed for axial sealing in coupling housings
• Operating medium: potable and non-potable water used in firefighting and transfer applications
• Function: provides pressure-assisted sealing to prevent leaks at coupling joint

How to use

Ensure the coupling faces and grooves are clean and free of debris before installation. Remove the old or damaged gasket and inspect the coupling for wear or damage that could affect sealing. Fit the replacement gasket into the coupling groove with even seating around the circumference. Reassemble the coupling halves and hand-tighten; perform a pressure test or visual inspection to confirm a leak-free connection. Replace the gasket if any cuts, deformation, or hardening are observed.

Usage recommendations

Store spare gaskets in a cool, dry place away from direct sunlight and chemicals that can degrade elastomers. Periodically inspect seals during routine equipment checks and replace them as part of preventative maintenance to ensure reliable hose connections in operational and training environments.
