What is a common use for compression fittings?

• A. For high pressure gas lines.
• B. For joining rigid pipes.
• C. For quick alterations without cutting pipes.
• D. For electrical conduit applications.

Answer: (C)

Compression fittings are widely used for quick alterations without cutting pipes, making them especially valuable in scenarios where you may need to make adjustments or repairs quickly. These fittings consist of a nut that compresses a ring (or ferrule) against the pipe, creating a secure and leak-proof seal. This feature is particularly beneficial in plumbing and HVAC applications where convenience and ease of installation are vital.

This approach allows for non-destructive joining and alteration of pipe systems, which can save time and minimize labor costs, as well as reducing the need for extensive tools. While other options focus on specific applications, the versatility and adaptability of compression fittings for modifications without requiring pipe cutting is a defining characteristic of their use.
