Ritchie 2 Foot Thermal Tube Extension #16416

Ensure your vertical water supply line stays protected from freezing with Ritchie Thermal Tubes. Featuring two inches of insulation with an impressive R-Factor of 7 per inch, these tubes have a 12-inch outside diameter and an 8-inch inside diameter. Designed using research from Iowa State University, they provide optimal size and performance for maximum water line protection.

The Two-Foot Extension allows you to customize your thermal tube setup by combining extensions and tops to achieve the necessary depth, ensuring protection at least one foot below your frost line.

TIP: Install flush with the top of your concrete pad.

• Offers premium protection to your waterline
• Two inches of insulation with a total r-Factor of 14
• Prevents frost from traveling to your waterline
• Use the 2 foot extension to combine with other thermal tubes to reach desired depth
• TIP: Do not cut or modify Thermal Tube. This will expose the insulation to the elements and deplete the insulation properties.
