Billet Aluminium Radiator Over Flow Tank - Black
Includes 5/16"" Barb Fittings & Mounts. 13" (325mm) Height x 2" (50mm) Diameter

When your radiator coolant gets too hot, it will blow through your overflow spout and all over your engine bay unless you have an overflow tank. Aeroflow's overflow tanks are available in polished billet aluminium or anodised black with 3/8" barb fittings for a simple installation. They will allow the coolant to expand and then recover as the temperature drops.

This tank features two -4AN male fittings end of the tank with two -4AN female to 5/16" (7.95mm) barb fittings. Constructed from 6061-T6 aluminium and includes two billet aluminium mounting brackets & hardware.

To plumb up this tank one fitting on the tank should go to the radiator neck spout. The other barb will be attached to long tube that is mounted inside the overflow tank. This is an extra barb that is designed if the tank gets too full it needs to empty so pressure is not built up inside. Ensure to plumb this barb away from moving components or extreme heat sources to avoid any damages or accidents.

Wonderful for dry feet
Material Type: Black - 3 Pairs, Size: X-Large
I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.

X-Large is about a size 12-13 shoe size foot USA.
Material Type: Black - 3 Pairs, Size: X-Large
I love them they work fantastic. I am a big guy with swollen feet. Wear size 12 to 13 USA Shoes. They fit me just fine not tight. My feet felt good after wearing them for two days. Some dry skin pulled off with them and it says to wash by hand. I dont know about the durability but I am hoping to get about 5 uses per pair. Before they become unusable.

Comfortable
Material Type: Black - 2 Pairs, Size: X-Large, Material Type: Black - 2 Pairs, Size: X-Large
I have very sensitive skin, so I usually need to wear socks at all times. These are especially comfortable because they don’t cover the toes, which helps with temperature control. The material is well-balanced—not too thick or too thin—and has just the right amount of stretch. I also appreciate the large traction area, which adds stability. Another plus is that they are completely fragrance-free.
