Mega Blue Silicone is a single component, moisture curing RTV (room temperature vulcanizing) silicone gasketing material that cures into a strong, silicone rubber that maintains long term durability and flexibility to make formed in-place gaskets.

Mega Blue Silicone is a non-slumping, paste-like consistency which cures when exposed to moisture in the air. Forms a tough, flexible silicone rubber gasket that resists aging, weathering; will not harden, shrink or crack. Remains more flexible than conventional gaskets.

Mega Blue Silicone is non-corrosive to steel, iron, and aluminum.

WORKS BEST ON: Use to replace silicone, cork, felt and rubber gaskets. Use on rear end housings, water neck outlet, timing gear cover, value covers, oil pans, transmission housings and intake manifolds.

Excellent product — exactly as described.

Used this on a JCB 3CX turbo downpipe. Fits perfectly, holds up very well to heat cycles. Much better than the fibreglass wrap I used previously — no itching, easier to handle. Will definitely be ordering again.

Great value, fast delivery.

Good quality wrap for the price. Arrived next day which was great. The 50mm width covered my headers nicely with a bit of overlap. Holds up well after a few heat cycles.

Decent product, application tricky without soaking first.

Wrap itself is good quality but I'd strongly advise soaking in water for 10–15 mins before wrapping — it makes it much more pliable and easier to apply. Didn't do this first time and it was frustrating. Product is fine though, no complaints.
