What type of sleeve is recommended for PEX tubing in construction?

Metal sleeve
Elastomeric sleeve
Plastic sleeve
Flexible sleeve

The correct answer is: Elastomeric sleeve

An elastomeric sleeve is recommended for PEX tubing in construction due to its unique properties that enhance the performance and durability of the plumbing installation. Elastomeric materials are typically rubber-like, providing flexibility, thermal insulation, and resistance to various environmental conditions. These qualities help in effectively protecting the PEX tubing from physical damage and temperature fluctuations. Using an elastomeric sleeve also assists in noise reduction associated with water flow within the pipes, making it a preferred choice in situations where quiet operation is desired. Additionally, the elasticity of the material allows for ease of installation and can accommodate movement and expansion of the PEX tubing due to thermal changes. This particular type of sleeve ensures that the PEX system maintains its integrity over time, providing a reliable and long-lasting plumbing system for construction projects.
