What happens to the joint if the fitting stretches?

When a fitting stretches, it can compromise the integrity of the joint, leading to potential leaks. As the material of the fitting expands or warps due to stress or excessive pressure, the originally snug fit may loosen. This loss of compression diminishes the effectiveness of the seal between the joint surfaces. Consequently, even a small gap can allow fluids or gases to escape, resulting in leaks.

Proper joint integrity requires adequate tension and sealing capability to maintain a barrier against leaks. Stretching undermines these principles, making leakage a significant risk. Understanding the impact of stretching on fittings is essential in water and fuel systems maintenance, as ensuring a proper seal is crucial for system efficiency and safety.
