Visbella V363 Silicone Oven Glass Door Gasket Seal High Temperature Heat Resistant from -80ºF to 600ºF (Black)

This is a great heat resistant sealant. The cap enabled me to easily pierce the tube, the supplied nozzle is easily cut to size with a Stanley knife, possibly a strong sharp kitchen knife on a chopping board. I applied a line of sealant waited the prescribed time and joined my components.I was repairing a broken switch plate on a slow cooker, so this needed to secure plastic to stainless steel, and be able to cope with the high temperatures produced by our slow cooker.The result was great, good, clean, strong bond that once again allowed us to set the dial to on, off, medium etc without the switch backing plate moving.Good results at a great price, would recommend this product for people needing a sealant that operates in high temperatures, with no smells etc.

Purchased this to help seal my internal oven glass in place after the catches for it broke off.Easy to apply, reasonably priced, and held in place really well. Highly recommend.

It’s easy to cut to the size you need, and it contours nicely around corners and curves.Great Adhesion (if surface is prepped): I cleaned the door surface thoroughly before applying, and the seal has stuck well so far. Definitely prep the area for best results.Improved Oven Performance: After installing, my oven holds heat much better, and preheating time seems a little quicker.

Used this to seal the glass on the oven door as had come lose . So far it’s worked brilliantly

Oven door was hanging off but this sorted it good and proper

Quite messy to use, and difficult to get out the tube. The supplied applicator that is cut to size is extremely poor quality and doesn't cut away cleanly with scissors.

Excellent and effective

Great
