Tite seal
Fixed my leaking intake. Worked perfectly.

Tite Seal Kit Intake Manifold Kit
The kit is high quality and well worth the price. Lowbrow is fantastic!

CURE FOR INTAKE LEAKS
EASY INSTALL, VERY HAPPY WITH PURCHASE. NO LEAKS

Seal kit manifold kit
Very good. Always a bit of a struggle to fit manifold and seals in place, but the seals are firm and fit well. Dual band clamps work well too.

Excellent
Good nice product very easy to install it was a great idea to seal up your manifold

tite seal
after 8 months of trying to cure an intake leak thought i would give these a try, anyway i ordered a set of these, within a few days it arrived, took the o rings off and put these on, went on really easy, used the supplied clamps , tightened everything up and started the bike expecting to still have a leak, lo and behold no leaks !, bike runs perfect now, done over 300 miles with these seals and still no leaks. excellent product wish i had bought these sooner. cant recommend these enough, will be ordering another set soon,bike is a cone shovel

Great product
Replaced old leaky rubberband gasket and clamp. Easy install and bike runs amazing, no leaks.

Good for leaky o-ring
I have a 74" knucklehead with o-ring conversion (done wrong), they ******* in the inserts too far and there was a huge gap between the intake spigots and the manifold. This will HOPEFULLY cure the intake leaks I've been having. Fits real nice and doesn't look too bad.

Tite seal kit

Tite Seal for sure
I got these to address vacuum leaks, the two little clamps per seal work great, they’re just kinda annoying to get on.
Tire Seal kit
So far, so good. Unfortunately it’s December 9th in northern Illinois which means I haven’t given the seals a good test, I’ll get back to you in the spring.
Wow
Looks good, but have not installed them yet. Fast service as always.
Bulletproof
I put these on all my motors. Way superior to the stock seals and will conform when the heads and intake manifold refuse to line up properly. Never have to worry again.
