What is a primary concern when choosing fittings for use in concealed locations?

When selecting fittings for use in concealed locations, safety and code compliance are of utmost importance. This is because fittings in these areas are often difficult to access once installed, which means that any issues arising from improper fitting selection can lead to significant hazards, such as leaks or failures that might go unnoticed until they cause serious problems.

Additionally, compliance with safety regulations and building codes ensures that the fittings used are appropriate for the application and capable of withstanding the environmental conditions they will face. For instance, specific materials and designs may be mandated to prevent issues like corrosion, which is especially critical in hidden areas where moisture may be present.

In contrast, aspects like cost, structural integrity, and ease of installation are also important considerations, but they are secondary to ensuring that the installation meets necessary safety standards. A failure to prioritize safety could result in dangerous situations that might compromise the entire system and put individuals at risk. Therefore, prioritizing safety and adherence to code is essential in ensuring the reliability and longevity of gas systems installed in concealed locations.
