Ed Cockill gets to grips with the new gasket maker range from Wynn’s.
The “OG” black gasket maker
We’ve all got a few bottles of this lying around the workshop. This is brilliant. It does a broad range of all kind of gasket making, be it your sumps or your water pumps or anything like that. It comes in a lovely 200ml bottle. It’s easily applied. So as a kind of general gasket maker, this is still brilliant. This will still get you out of trouble with most stuff, but the good thing is about their new range is they’ve gone into real specific functions for each gasket maker. So let’s have a look at each one.
The New stuff
In Wynn’s new range, they’ve got three different types of gasket maker: Black, red, and grey. The black is similar to its predecessor, but it’s got some better qualities in this one. The temperature resistance is a lot better. The previous one was 232˚C. This one’s up to 260˚. Compared to its predecessor, the oil resistance is a lot better on this and also it’s safe to use around sensors, so you can be happy knowing that when it’s around any sort of sensor or anything like that, it’s not going to affect the readings.
Seeing red
So next up is the red gasket maker, so the same sort of formula, the same qualities as the black one, but the difference is with this is it takes really high temperatures, stuff like inlet manifolds, turbochargers, stuff that gets really, really hot. It’s guaranteed up to 300˚C, but it can also go up to 340˚C intermittently. So you can guarantee that this is going to work on really, really high temperature stuff and it still works fine with oil, fuel and coolants, so you can still be able to use it on other stuff.
It’s a grey area
The main qualities of the grey gasket maker is the fact that it’s torque and vibration resistant. So anything that’s rotating on an engine, there’s quite a lot rotating on an engine, but stuff like water pumps and bits and bobs like that, this stuff is brilliant for it. Also, the coolant resistance is a lot higher than the black and the red gasket maker, so it’s ideal if you just want to keep water in anywhere, because obviously water or coolant, the viscosity is a lot lower than most oils, so this will keep it sealed and tight in the places it’s meant to be. The main applications for the grey gasket maker is water pumps, thermostat housings, gearboxes, anything that involves coolants and thinner fluids and anything that’s got any rotating parts on it. This stuff is brilliant.
Just the cure
They come in a lovely 80ml tube, which is a lot easier to justify billing to a customer. If you’re trying to bill a 200ml gasket maker to a customer, it’s not really fair. Whereas with this, it’s a lot easier to bill. Lastly, a word on curing times. People just think you can put sealant on and send it out the door, but that’s not true with anything that’s submerged in oil, like oil sumps, timing chain covers, timing belt covers. The recommendations from the manufacturers and from Wynn’s is to leave them for twelve hours, so overnight, whilst the minimum cure time for anything that isn’t submerged in oil or fluids is around three hours.
