what is a good type of gasket sealant for sealing up drive flanges and the like, i am using the thin paper gasket ,flange and hub have no burrs on them , I nip the bolts up first then tighten diagonally bolts are not too long for hole.but oil still comes out.I have to clean oil of rims about once a month thanks from leyland

Loctite Flange Sealant 515 .
I use on all flanges including hubs, swivel to axle anywhere where those silly paper gaskets are. No leaks anywhere.

Hi,
for any paper gasket just use a smear of grease. Its good for oil and water. also less messy and dosn't stick the gasket to the surfaces. Nothing worse than trying to remove a stuck on gasket!!!

I use the 515 instead of paper gaskets. Its the modern solution like in place sump gaskets. It doesn't make a mess at all, but remains pliable.
Regard sPhilip A

i use VOLVO truck goo sealant i buy big drums of the stuff for work the volvo reps give me a good deal..its the same as the stuff you get els where black gooy stuff... every gasket on me serries 3 has it no leaks yet...(yes i did say yet)..LOL

thanks philipA, I will try the loctite

I use a Aviation (Black & gooye) // Comes in a plastic bottle and is applied by brush
It stays plyable and never goes hard .... Messy stuff tho if you spill it .. available at most good motor shops .... Never have leaks again!!

Be aware that some gaskets only require what Kie4 said

This is what's required for things with oil feed holes, as it prevents, excess silicon/sealant coming adrift and plugging the holes......very common failure for LT95 intermediates shafts and the like

I use ^^^^^^, 3bond, and gasket maker, dependant on application, for swivel hubs, flanges etc, its just gasket maker

thanks mike, and kie4, re your grease, in this case we definatly don't want to lubricate the joint. you are quite right for many other joint sealing applications.

good stuff and exactly what i would use, however the paper gasket isn't as silly as it seems. fitted correctly without any sealant or lubricant will probably last very well as the joint faces we are talking about are very well machined surfaces. however i prefer to use the paper gasket and the locktite 515, 518 series of sealants.

with the axle to hub attachment, the last thing we want is a lubricated joint - movement in this situation is the enemy of this fixture.
if the axle flange is able to move, not only do you get leaks, but also the transmission of the driving force is transmitted to the bolts.
in the correctly assembled axle to hub situation the driving force is transmitted to the hub by the the clamping force of the bolts holding the axle flange to the hub. the bolts aren't designed to take the driving forces, and if the joint is allowed to become loose you will soon learn this in a very practical way - if left long enough you will experience broken bolts and maybe all, causing total loss of drive to that axle.
also ensure you torque the attach bolts correctly and apply loctite to the bolt threads.

Just to clarify, the 515 will set in the joint anaerobically.
For example with an axle, you have to give it a sharp tap ( or two) with a persuader for the joint to separate, but it is pliable enough to seal.

I guess the lubrication referred to grease in the joint.
