Frequently Asked Questions
What are copper ring kits used for on ships?
Copper ring kits are used to create leak-tight seals between flanged pipe connections, valve bonnets, heat exchanger covers, and similar jointing applications where a soft metallic gasket is required.
Are copper rings suitable for seawater systems?
Yes, copper offers good resistance to seawater corrosion, making these rings a common choice in marine cooling, ballast, and general-service piping systems.
What sizes are included in the kit?
The kit contains an assortment of popular imperial and metric sizes, typically ranging from 1/4" to 2" (6 mm to 51 mm) inside diameter. Exact contents can be confirmed by the package label.
Can copper rings be reused?
Copper is a soft, deformable material, so rings are intended as single-use jointing items. For reliable sealing, always install a new ring after breaking the joint.
