Is brass resistant to coolant?

All the metals in a cooling system will corrode under certain conditions. The metal most prone to corrosion in a cooling system environment is aluminum (see photo). Cast iron, solder, steel, copper, and brass will also corrode.

Can you use an fittings for coolant?

The most common uses of AN hoses on race cars: -6 AN fuel or coolant hoses. -8 AN a very common size for coolant and oil. -10, -12 AN fittings are used on either coolant or vent hoses.

Can I use brass fittings on aluminum radiator?

Brass and aluminum are chemically a no-no. They don’t really go together and have the possibility of forming corrosion between.

Is brass OK with Aluminium?

With a thick enough coating, even a very reactive metal like brass can be used on an aluminum structure without corrosion. Since stainless steel remains one of the least reactive metals without coating, it’s smarter to use it as the base material.

Does glycol corrode brass?

The main job of glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating temperature. Inhibited glycols will also prevent formation of scale and corrosion while protecting metals such as brass, copper, steel, cast iron and aluminum.

Does antifreeze react with copper?

Modern antifreeze contains corrosion inhibitors such as silicate/phosphate mixtures that form an insulating film on metal and should help prevent any issue with the copper parts.

Why are an fittings red and blue?

It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN. The Army-Navy involvement is also the origin of the red/blue color combination that was traditionally used in the anodized finishing process.

Can you use rubber hose with an fittings?

Rubber line hose ends may be swagged or crimped onto the rubber line. Finally, rubber hoses are more resistant to vibration when you use the appropriate fittings. However, rubber lines cannot stand as much external force as braided lines.

How do you remove brass from aluminum?

Start by applying pressure clockwise briefly and then twist ccw. Sometimes a stuck fitting will twist the wrong way a bit which can help to free it up. Brass is soft so use the tightest socket you have or fitting wrench. Use your head and keep an extinguisher handy.

Does copper react with aluminium?

Aluminium appears less reactive than copper. The aluminium foil appears unable to displace copper from copper(II) sulfate solution. This allows a simple exchange reaction with the copper(II) sulfate. The protective oxide layer forms instantly the aluminium is exposed to the air.

Can brass fittings be used with stainless steel?

Using brass fittings on stainless steel tubing is not recommended. Brass is softer than steel and may not seal onto the tubing as well, risking leaks. You might also see galvanic corrosion, which is a process where the corrosion is accelerated by 2 dissimilar metals contacting one another.

Can you mix steel and brass fittings?

Stainless steel pipes and brass pipes and fittings work together better than stainless steel and copper. The reason is because only certain types of stainless steel and brass can be used together. If the wrong types are used together, the system will experience galvanic corrosion.

Can you use brass fittings for a gauge pod?

Brass is just a mix of copper and tin or something like that so Im assuming it has similar properties. installed the gauge today see how it goes. need to finish off making a bracket to support the brass fittings as they are a bit heavy and may damage the heater hoses after a while. also in desperate need for a gauge pod on the dash.

Is there a rust inhibitor in the coolant?

It won’t touch the radiator but those 2 parts will eventualy corrode together. Yes, the factory coolent contains a rust inhibitor. looks like either way the cooling system has a bit of electrolosis already.

Can the factory coolant touch the radiator?

Im assuming the factory coolant Is a corrosion inhibitor as well as anti freez anti boil, Im a bit hesitant and dont want to distroy my radiator but on the other hand I think the coolant temp sensor and welsh plugs may be brass or copper, so it might not be too bad. It won’t touch the radiator but those 2 parts will eventualy corrode together.
