Easy to install
I saw a few reviews that the tube is hard to use, or its hard to apply. One, the hardest part of applying is seeing what idiot replaced the gasket on your stove last. It was probably you, sorry, but I bought a home where the previous owner I don't think ever replaced the gasket so it was a mess and/or missing. First thing you need to massage the tube to ensure any water/liquids that might have left the epoxy are mixed back in. Don't need to go crazy just rub it between your hands and squish it a lot for a while, I spent like five minutes or less. Next, chisel out all the old gasket, and wipe down the channels with a solvent if you can. If you don't have the right tools you can use a screwdriver or a cold chisel.. just be careful you're chipping off gasket and not beating a tool INTO the cast iron (it'll break). Measure the channels using the right size gasket for the spot (doors are biggest, griddle is next, windows are smallest diameter). The fiberglass stretches, don't pull it taught as you measure, let it lay loose in the channel to measure you can always trim again. Fiberglass is a PITA to trim when woven so I used big wire snips. If you have a bit of striping or painter's tape you can wrap the spot you're going to trim and cut it so the ends don't fray. Now, cut a small bit angled off the end of the epoxy tube (cut less, you can always cut a little bit more later). It will take pretty good strength to squeeze it out- this part sucks, basically either roll the top of the tube to help apply pressure or just mash the bottom of the tube towards the nozzle with your palm as you apply. Make a continuous 1/8" bead (that's the manual instructions) and lay the gasket on top. Easiest to do with the doors/griddle off (just lift them up). Put them back on the stove but don't close any of them- take parchment or wax paper and lay sheets inside the doors and under the griddle before closing just in case the epoxy leaks through and accidentally bonds anything closed. You can then close them with the parchment paper over the channels. Wait an hour before firing the stove up. It might be 24 hours but the instructions are in the package. Not hard, did it in like 20 minutes.

Everything needed
Bought this product about two years ago and just used part of it to replace the gasket under the griddle on my Vermont Castings Intrepid stove. Unfortunately, the Rutland cement was no longer fresh and wouldn’t squeeze out of the nozzle tip because I waited way too long to use it (no fault of the vendor) so I had to slice the tube open and finger paint a bead into the gasket channel. Installation of the cut gasket went perfect. Set came with excellent instructions for those who haven’t done this before, Good value for every gasket needed to service my stove.

Convenient and made my life easier!
Great to find all I need in one bag. Needed this for my Vermont Castings Stove of 40ish years.

Kit covers most gaskets for Intrepid II.
For a Vermont Castings Intrepid II there is a gasket behind the rear fireback wall. Would be nice if the kit included that. Otherwise the kit was complete - top griddle, front doors, door glass. The cement was in good shape, others have complained. I shook it hard and kneeled it a lot before opening. There was enough cement for the griddle and fireback gaskets. I might have needed more if I replaced the door gaskets too, so order an extra tube if you’re replacing all the gaskets.

Kit de cordes et joints pour poêles Intrepid II
Ce kit est un peu plus dispendieux mais après avoir acheté plusieurs et plusieurs cordes différences partout et rien faisait sur notre poêle Intrepid II, nous avons trouvé ce kit, complet. Il y avait toutes les cordes avec la colle. Il faisait très bien. La seule chose c'est la corde sur la porte sur le dessus que nous ne comprenons pas trop, elle semble toujours vouloir décoller. Sinon, le reste est one on one! Je recommande.

Exactly what I needed. Perfect
So happy I found this for a good price. Comes with more than you'll need of everything. Glue wasn't separated like in some reviews. Rolled the table in my hands and it was perfect. Be careful not to cut too much off the tip until you test some (more than enough in the tube for the job). I cut too much off and wish I would have cut less. Would have been way easier to apply as you don't need much
