I was running 1/2 copper tubing for an outdoor faucet and needed copper tape and nails. You can not mix steel and copper - galvanic reactions will occur, which will lead to corrosion and possible pipe leaks in the future. Both Lowe's and Home Depot were out of stock (COVID/supply chain issues/theft etc at work) so I ordered from Revane. Arrived quickly, copper clamps mounted - pipes don't knock. As copper prices go up, I can add the nails I didn't use to my estate. Hope that helps!
