What is the maximum number of turns a hand finger tight nut on a compression fitting may be turned?

• A. 1/2 turns
• B. 1 1/4 turns
• C. 2 turns
• D. 2 1/4 turns

Answer: (B)

In the context of compression fittings, the maximum number of turns that a hand finger tight nut may be turned is crucial to ensuring a proper seal without over-tightening, which can damage the fitting or the piping material. The accepted practice for many compression fittings is to tighten the nut to the point that it is comfortably secure without excessive force. Turning the nut 1 1/4 turns is sufficient to achieve a proper seal for most applications, as this allows the rubber washer or seal to compress and create a tight fit against the fittings. This amount of rotation provides an optimal balance between securing the fittings and preventing any potential damage that can result from overtightening. Ensuring that compression fittings are tightened appropriately is critical in maintaining the integrity of the system, preventing leaks, and ensuring safety in applications involving fluids or gases.
