Daiwa magnetic seal service

Any updates on Mag Oil or its substitute?
Thinking about buying a mag-sealed Certate and its really annoying that Daiwa does not sell this oil

What was the solution?

Wolli · January 26, 2016, 06:26:36 PM

guess this the stuff they use.

https://ferrofluid.ferrotec.com/products/ferrofluid/vfFerrofluid

I ordered one small 10ml bottle (EUR 9.50) from a German company and waiting for first inquiry to service one of the new reels....

Let you know if it works.

Thanks to Reel Speed I ordered the oil from Southwest Speakers. It's used in high end speakers and it does work with the spinning reels.

Hi,
Does the ferrofluid from Southwest Speakers comes with MSDS? Any info on the "recipe" will be very useful.
Thanks!

Look on the Ferrotec site,
APG L series high colloidal synthetic ester base oil.
900uL (ie <1mL) of oil will do a bunch of reels.
Anything you buy off ebuy or other places may be hydrocarbon or even water based; be very careful if it is cheap! Someone from Asia was selling a 10ml or so bottle for about 10bux but was a bit cagey as to what the base oil was.

Thanks Steve. Precious info!

I found a few more sellers on ebay. I'm inquiring regarding base oil of this one.
Also found a few from Australian dealer, APG L11 and APG WO5, same base oil but different magnetization and viscosity. May be more viscous WO5 will be preferable?

hello boys and girls my first post here! are hydrocarbon based ferro fluids good for magseal service ?

IMHO, no.
Hydrocarbon oils may evaporate faster over time, usually don't handle moisture well.
The oil I have recommended is synthetic base, high colloidal (ie sticks to itself, therefore holds in the gap better, less fling out on rotation), and has moderate moisture resistance. I don't believe you should go too high on viscosity as the seal may well "tear apart" rather than hold in the gap (hence high colloidal). However, I am not a fluid dynamics engineer! I would not use it unless the supplier can supply a tech data sheet and MSDS so I know what is in it. Remember also that the active component is ferric oxide (basically RUST!) that is only kept in check by a coating on the particles to stop them clumping together and forming a large rusty mass!

Perfectly makes sense, thanks Steve.
BTW base oil of ferrofluid from ebay seller I posted before is unknown, unfortunately.

Thanks for all this info guys. Any news on how this substitute is holding up to the test of time compared to the original stuff?

swoffer · April 25, 2016, 02:38:27 PM

Hi guys , I know its a much asked question , but with a little time having passed , any updates ?

Im keen to get the "good oil" so to speak because as time goes by im having to say no to more and more customers when it comes to Daiwa .

Cheers Al

All I can tell you is the reels with the pinion mag seal does not work. I've had too many in the shop replacing roller clutches and pinion bearings because of rust.

The ones serviced that aren't rusted get oiled agin. The ones repaired get oiled again. They haven't been back yet. The owners may have sold them.
