Big Block water hose fittings

The two fittings on the water pump housing, anybody make those in stainless ?

Classic Industries carries some on their website. Not factory appearing if you care about that sort of thing.

Hoffman Winners Circle probably has the best fittings.

Wouldn't that create a problem with an aluminum pump housing (assuming it's not iron)?

what kind of a problem ?
a good coating of Loctite 567, which is my favorite sealant, will seal the fittings and prevent any galvanic corrosion if you are worried about that.

Do they make them in aluminum? I put s sealant on mine like was said. Was fine for years. Not sure how long it’d take to see a corrosion issue.

I think aluminum would be too soft.
Agree on using thread sealant.
Haven't needed any heater hose fittings for a long time, but they're available from vendors.
But if you use brass, it's invisible when the hoses are on.

Nice thing about brass, it doesn't 'grow attached' to either steel or aluminum. Miracle metal.

Loctite doesn't state it can prevent corrosion, just a low strength sealant for course and taper thread fittings.

I use solid brass ones from Grainger on

They're listed as "Beaded Hose Fitting"

I especially like that they can be insalled & removed with a deep socket.

just make sure you get the correct NPT size
