The whole valve comes apart with an allen key and a spanner for easy cleaning if it ever does clog up on you (if you look closely at the poppet, you’ll see how to disassemble).

I've been on the Fillmore valves with silca sealant long enough to be about due for my second top off. It has been flawless. Compared to mucoff or Stan's valves who's cores I would have to change out about once a month, it's a welcome improvement.
For the silca sealant, it's been perfect as well. Stans, mucoff, orange sealants would seal small thorn punctures but would always weep and leave constant wet spots. Same tires, same holes, cleaned up and filled with silca are bone dry.

It took about a year, but eventually I got some build-up in my Filmore valves using Silca sealant. They were still working fine, but I could feel the valve didn't have as much travel as before. Thankfully, you can disassemble the valve and clean it out. Getting all the gunk out was a pain, but I was being extra particular about removing everything. If I only have to do this once a year, I'm happy with the expense. I was cleaning or replacing the standard valves every month or two. The standard ones are cheap, but a constant hassle - to the point I was considering going back to tubes.

Thank you for this, I'm considering a switch to Silca and my current sealant (which is quite good... Muc Off has been a bit better than Orange Seal) is already sealing my valve stems.

Yesterday i used a drink straw brush to clean inside the valve body with sopy water...it works!
Also completely loosen and clean around the seal on the vittoria

I have given up getting sealant through a valve and now just fill the tyre with it nearly fitted, then just push the tyre rim over the wheel rim. I change/clean valves every so often.

I've had my Fillmore's for about 8 months. They are not clogging so much I cannot add air but I am unable to add sealant thru the valve. I took them apart and there is some minor sealant build up. For the price and the eventual clogging I would rather just deal with replacing cores on normal presta setup.

I have a pair of these valves on my mountain bike, which actually have stans valor, carbon wheels. Of course they’re very narrow and I have no problem seating a bead on this wheel set however, I have some hookless wheels on my gravel bike, and mounting tires is a real bear and monster of an ordeal. very time-consuming there must be some dimensions that are off or not the standard. at any rate I’m gonna try to add sealant through the tire and see if I can Seat the bead back on without making a mess or adding to my frustration I would prefer to just do it through the valves, but that might not be possible time will tell.

I can confirm that they are worth the price. No more clogged valves after 2 years on 3 wheelsets

This video and the disassembly short might’ve sold me on both the valves and sealant. I had my first case of a gunked up core with Muc-Off valves and Bontrager TLR sealant (came stock), and I‘m interested in not having that experience any more than I have to, ha.

WRT the spray.... dont let the air out with the valve at the top where the sealant puddled in the body ., put it at the bottom so the sealant drains out.

Using the same setup, curious too on the long term effects and with the silca top up fluid. Have 3 bikes on the filmore valves, never tried adding sealant thru the valve.

Great video! Is the Fillmore valve ideal for use with all tyres? Or does it depend if the rim cut out for the valve is square or round?

[youling]

Particles in my mucoff sealant can’t get thru and clogged my Fillmore. 😢. I have to take it apart and clean it up. Which is a pain in the ass since my fat bike tubeless setup is not easy.

worth the 50 bucks. never going back to reg valves again

[williamforbes]

this biggest turn off for me, just seeing this now, i can afford a 19.99 bag of valve cores on amazon so those aren't a big deal but when i used silca the internal of my tubeless would junk up and the reserve don't appear to be as user friendly. i've also swapped from silca from stans and now trying orange as it comes highly recommended from my local rei (was on hand) i've seen some latex on amazon for decent bulk prices in a blue jug as well as american classic tyres for thrifting the cost savings.

[rayFrio]

Was this test with the tire insert in? Could the reduced volume in the tire be increasing the Silca foaming action from the valve depression? Would love to know if the sealant acts the same without the tire insert.

Use Flat-Out quickstrike off-road formula

I'm a mechanic at a high end race shop and we used to offer the Silca sealant in our service course as we are a pretty big Silca dealer. This was last year. This year, we've done away with offering Silca sealant at all. Why? Because a. You can't install it with a syringe (not a huge deal for the most part.. but with some tire/rim combos this can be an absolutely shit-show) and, b. It clogs every valve known to man. It has clogged my own valves so badly that I have had to replace them every month or two. This is just my experience with this stuff. While, yes, it will clog a puncture, just watch out for it clogging your valves as well.

[Fear.of.the.Dark.]

if you keep your wheels at rest with valve at 4 or 8 o clock position, you will have less of these issues.
