S-S-Lok twin ferrule fittings are a type of compression fitting used in piping systems to connect tubing and provide a leak-free seal. They are designed to provide a secure, tight connection that is resistant to vibration and thermal cycling.
S-S-Lok fittings consist of two ferrules (compression rings), a fitting body, and a nut. The two ferrules are placed over the tubing and compressed onto the fitting body as the nut is tightened. The front ferrule is typically made of softer material than the back ferrule, allowing it to create a seal against the tubing while the back ferrule provides support and prevents the tubing from pulling out of the fitting.
