This seals gas and diesel and kerosine if surfaces are properly prepped.
This worked well while installing the on off reserve shut off on an aftermarket motorcycle tank. It dried to a firm gasket and no leaks showed up. It has a 24 hours drying time. It is the consistency of standard RTV. There is not a tapered applicator in this package.

GREAT PRODUCT TO HAVE
I use this product on all the engine rebuilds I do on my mopeds engine cases, works great and seals up all and any air leaks.

Works as it should, be mindful of the consistency.
I used this to reseal the rollover valves in a plastic fuel tank. This sealer in combination with a new oring worked flawlessly. This “RTV” is definitely thinner than your normal RTV, but not so thin it just runs all over.

Fuel specific sealant that holds up well
Great product, completely fuel proof once cured. To be very clear this product is very thin, just a tad thicker than dish soap. So prepare surfaces accordingly and be ready for drips. Great sealant and does cure to be soft and fairly flexible. I had cleared out a through hole a bit oversize when replacing the fuel line for a leaf blower. added some of this and was able to seal right up. If there is any gap, you want to block with something until it cures, washer, cardboard, clay, etc. Anything to stop it from flowing away from where you want it to be. I 3d printed something for my needs, but that is a bit overboard for normal use If using it on a gasket, would hold and seal well without issues, will not be thick enough to flow anywhere. Tacky enough to hold item in place while horizontal. If vertical would need to be clamped.

great for stihl chainsaw case halves
I rebuild chainsaws, this is a great product for case halves that are exposed to gasoline. i have been looking for a cost effective readily available alternative to dirko and yamabond, this has worked well. I do wish however that it came with the plastic nozzle. Sets up quickly, and has held up well.

ガスケットの使い方なんて特にないので問題ありません。 キャブレターのガソリン漏れの応急処置に使いました。 一ヶ月立ってガソリン漏れが再発しないのでけっこうガソリンには強いようです。

Over the years I have tried many brands, this isnt cheap but the best by far.

Shipping was really fast, and it worked for my engine case on my dirt bike after I split it to repair transmission

ガソリンホースの継ぎ手部分に使おうと購入しました。金属バンドでだいたい漏れないようにはなっていますが、安心料として使いました。今のところ漏れ無し。 しっかり働いてくれています。色が乾いても灰色っぽいので、(私の場合は)黒色なら目立たなくてよかったなぁと、わがままを感じています。
