Can bushings be used on gas piping?

Bushings are fittings used to reduce the size of a pipe or connect different sizes of pipes. In the context of gas piping, the use of bushings is restricted because they can potentially create weak points in the system, leading to leaks or failures. This is particularly critical in gas systems where safety is paramount, as the consequences of leaks can be dangerous.

Gas piping systems must be designed and installed to minimize the risk of leaks and ensure the integrity of the system under varying pressure conditions. Using bushings can introduce a risk that is typically avoided by using more robust and reliable methods of transitioning between pipe sizes or securing connections, such as using properly sized straight fittings instead.

Therefore, stating that bushings can never be used emphasizes the importance of maintaining a high standard of safety and reliability in gas piping installations, aligning with best practices and guidelines in the field.
