What devices are utilized to protect corrugated stainless-steel tubing (CSST) from punctures in various structures?

Protective sleeves are designed specifically to safeguard corrugated stainless-steel tubing (CSST) from potential punctures or physical damage that could occur in various structures. These sleeves are typically made from materials that provide a strong barrier against sharp objects, impacts, and abrasion, ensuring the integrity of the CSST is maintained over time.

The function of protective sleeves is crucial, especially given the flexibility and installation environments of CSST. Environments that may have sharp edges or possible impacts from nearby objects make the use of protective sleeves not just advisable, but often necessary to prevent leaks, which can lead to hazardous conditions.

Hangers and clamps, while they assist in securing tubing in place, do not provide the protective layer needed to guard against punctures. Steel braces may offer some structural support but lack the protective quality required to shield against direct contact damage. Specific fittings are important for the proper connection of CSST to other piping or fixtures, but they do not serve the primary role of protecting the tubing itself from external harm. Thus, the most appropriate device for this purpose is the protective sleeve.
