RE: 2004 SE

I'm changing all my hoses and don't want to pay the stealership tax for the hose clamps.

Can anybody identify the correct spring hose clamps from an aftermarket supplier?

It looks like the constant tension spring type clamps have a narrow operating range and I'm not confident of guessing the size.

I'll even consider the Gates polymeric bands, although they are a completely new technology to me and I don't know if they easily available.

Mazda parts numbers are 9WNC-B3-400 (large), 9928-62-200P (medium) & 9928-71-600P (small).

Just take them to a nut and bolt supplier and ask for some, most of them stock assorted other fittings (like clamps)

They can match them to their stock.
It will likely be cheaper than Mazda/Bunnings as well.



If it were me though, I'd just throw out the factory ones and use some good quality worm clamps. I think there are some now available that provide constant tension.
Next time you need to replace a hose you'll thank yourself.

get some screw type ones and bugger off those stupid cheap spring ones.

Try and get this style with the squared end



NOT these



The squared end ones makes it much easier to grab in tight confines
