Frequently Asked Questions

AI
Generally, no. Compression rings, or ferrules, are designed to be crushed into the pipe to create a seal. Once they have been deformed to create that tight grip, they cannot be effectively reshaped to provide a reliable, leak-proof seal if removed and reused.
Brass is widely used for general plumbing and copper tubing due to its ease of machining and corrosion resistance. Stainless steel is typically reserved for higher-pressure systems or more corrosive environments where extreme durability is required.
You must match the ring size to the outer diameter (OD) of the pipe being used. Using a ring that is slightly too large or too large will result in a leak. Precision is key; always check the pipe specification before purchasing.
