How it works and how to install
Copper washers are used between the sealing surfaces of fittings, drain plugs, or couplings. Choose the appropriate size for the external thread diameter, position the washer on the clean surface, and tighten uniformly. Copper deforms slightly under pressure, creating a perfect seal that resists vibrations, high temperatures, and chemical agents. It is recommended to replace the washer with a new one from the set after each disassembly to maintain optimal sealing.
Frequently asked questions
Can I reuse copper washers after disassembling them?
Reusing copper washers after disassembly is not recommended. Copper permanently deforms during the first tightening, so a used washer no longer provides a complete seal. The set contains 100 pieces to cover multiple interventions.
What exactly do diameters like 6mm, 8mm, or 14mm mean?
The indicated diameter represents the inner diameter of the washer, corresponding to the nominal diameter of the bolt or fitting. For example, an 8mm washer fits on an M8 bolt or a fitting with an 8mm thread.
Can I use these washers for natural gas installations?
Yes, copper washers are compatible with natural gas, LPG, compressed air, and various fluids. However, ensure that you comply with local regulations and that the washer size exactly matches the fitting specifications for maximum safety.
