Stainless Steel Coolant Tubes Done Right

100% Made in the USA by Southpointe Radiator

They say if you want something done right, do it yourself. After exploring all the options in Coolant Tubes offered in the heavy-duty truck market, that’s exactly what Southpointe Radiator decided to do.

Southpointe Radiator is located in Taylor Michigan and has been family owned for more than 40 years and has three generations of heavy-duty specialists. The viewpoint in product offerings stemmed from a simple premise – if we wouldn’t want it in our own truck, we won’t sell it for theirs. When it came to Coolant Tubes what they found was a product consisting of a 400 series, or martensitic type, steel which is very hard but because of the makeup becomes brittle.

Stainless Steel The Right Choice

This leaves the tube susceptible to rust and compromises its overall strength and durability. Other considerations were the process of forming the bend as well as the methods used for cutting the tube and applying brackets. None were found to be within the high standards of Southpointe Radiator.

Southpointe Radiator begins with an austenitic, 304 surgical stainless steel consisting of 8-10% nickel and 18-20% chromium making them not only resistant to rust but keeps the overall integrity through road debris and the elements. A mandrel bend allows for an extremely tight radius while keeping the tube wrinkled free allowing a full flow throughout the tube.

Smooth bore dies are used for burr-free clamping and a water jet is utilized to cut flanges and brackets. The tubes are also completely tig welded with a 308 series rod in keeping in line with the rest of our high-quality standards. The entire process gives it a better fit, is safer to handle, has a better appearance, and keeps the overall function more consistent.

Being offered a lifetime warranty on any product is certainly a great selling feature; one that gives a customer peace of mind that they will not need to pay again for a part on their heavy-duty truck. However, with all the abuse the truck takes while running down the road, Southpointe Radiator believes that it’s better to offer a product that lasts a lifetime. Made in the USA right in their shop in Romulus Michigan, Southpointe Radiator proudly makes Stainless Steel Coolant Tubes – done right.
