gasket
A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. It is a deformable material that is used to create a static seal and maintain that seal under various operating conditions in a mechanical assembly.Gaskets allow for "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials. Given the potential cost and safety implications of faulty or leaking gaskets, it is critical that the correct gasket material is selected to fit the needs of the application.Gaskets for specific applications, such as high pressure steam systems, may contain asbestos. However, due to health hazards associated with asbestos exposure, non-asbestos gasket materials are used when practical.It is usually desirable that the gasket be made from a material that is to some degree yielding such that it is able to deform and tightly fill the space it is designed for, including any slight irregularities. Some types of gaskets require a sealant be applied directly to the gasket surface to function properly.
Some (piping) gaskets are made entirely of metal and rely on a seating surface to accomplish the seal; the metal's own spring characteristics are utilized (up to but not passing σy, the material's yield strength). This is typical of some "ring joints" (RTJ) or some other metal gasket systems. These joints are known as R-con and E-con compressive type joints.
My parents have a leak from kitchen sink. My dad removed waste trap and since refitted it leaks, but there wasn’t any kind of seal on it, I got a rubber/plastic gasket that seems
To fit the trap but with it, I can’t get it to screw and lock back on (has lugs so locks after quarter turn. But...
Hello, I have 22 year old water tank boiler in a rented house. While the burner was lit yesterday I smelt a very faint smell of gas. It was confirmed it was leaking only when heating up, and yesterday the gas engineer found there was no gasket under the burner.
It could have been like this...
Hello, I've got a Main Eco Elite combi with a gap in the sump gasket (pretty sure that's what they call the part) so POCs are escaping, so needs to be replaced.
Has anyone got any idea how long this is likely to take? I can't work out if the hole heat exchanger needs to come out or whether the...
I managed to get the broken shower waste body out of the trap. I'm about to fit a new waste, a much more robust brass item.
The trap has a big rubber gasket designed to sit flush against the underside of the shower tray.
Is it a good idea for me to fit a rubber gasket between the flange on...
I get water coming through the ceiling under the upstairs bath whenever I run the taps for a long time (such as filling the bath). I also got the same leak when using the power shower (completely different incoming water supply pipe, but above the taps). I assumed water was getting under the tap...
hi guys. I’ve changed a heat ex gasket on a 24ri today and it was the 1st one I’ve done. For the life of me I couldn’t seem to get the whole thing flat. I put the analyser round it to check for anything passing and didn’t pick anything up. My colleagues reckoned it looked sound but I’m after...
Hello,

ECOMAX 828 I have replaced these before on the ecotec range and the new burner is a complete re-designed part but it looks like there is a replacement flange only for this older version ?? any advice from you lot
Hello.
Whilst replacing my immersion heater, I came across this washer.
Is it made of asbestos? Is there a way of telling?
The cylinder must be from the 60's or 70's, but I'm assuming the heating element has been changed since then. The existing one's been in place since 2006 at least...

Hi
I would appreciate some advice as my boiler has a small leak from cold water feed
at the back of boiler. The bit where the copper pipe feeds into the cold water inlet filter.
Is it possible to fix this easily myself, or how much would it cost for a plumber to fix.
Thanks

Hi all - first post here so please be gentle.
A rubber gasket/reducer has broken free from my soil stack, above the roof line and before the vent/terminal.
It looks like a reducer/gasket to keep the joint between the larger outer pipe and the smaller diameter inner pipe water tight.
Does...
Hi,
The boiler in our recently rented house needed some unrelated work. Upon completion, the gas fitter noticed the gasket on the burner had failed such that we could actually see an orange glow and the electrics above had burn damage from intermittent flashes. Of course he stuck "IMMEDIATELY...

I have an old toilet in a downstairs cloakroom and there is a bad smell when the room is left closed up. No smelly bottom jokes please.
It has a swan neck from the back of the pan straight into a soil pipe. I think the gasket that seals the two has perished and allows foul air to escape into the...
