What is the difference between a short rod nut and forged in regards to flared tubing?

A short rod nut is a type of nut that is specifically designed for use with flared tubing. It is similar in design to a regular hex nut, but it has a shorter body and a larger diameter. The short body allows the nut to be securely fastened to the flared tubing without interfering with the flare. The larger diameter provides more surface area for contact between the nut and the tubing, which helps to prevent leaks.

Forged nuts, on the other hand, are made by hammering hot metal into a mold. This process creates a strong and durable nut, but it is also more expensive than a short rod nut. Forged nuts are typically used in applications where strength is critical, such as in automotive and construction.

In general, short rod nuts are a better choice for flared tubing applications because they are less expensive and provide a more secure connection. However, forged nuts may be a better choice in applications where strength is critical.
