Details

Specifically designed to work with tubeless systems.

76 Projects' HI FLOW valves have 4x the air throughput and a redesigned core that helps prevent sealant build-up.

Tubeless bike tyres and rims were introduced 20 years ago yet tubeless systems still use the Presta valve standard from the 1890's. The clearances in a Presta valve are smaller than the holes that sealant is supposed to be able to block so it's no surprise that the valves get clogged.

  • 'No Clog' internals - Greatly increased clearances prevent sealant build up*.
  • 4x greater air flow (compared to Presta) - Fill the tyre faster to help seat and seal the bead.
  • Works with lever lock Presta pump heads. An adapter may be required for other pump head types, see below for more details on compatibility.
  • Sealant can be directly injected through the valve centre, see below for more details.
  • High precision CNC machined aluminium.
  • Spare parts available here.
  • Sizes 0 & 1 Compatible with rim protection inserts.
  • Compatible with push-on CO2 inflators, adapter required for screw-on inflators.

      Some sealants with very large particles such as Silca Ultimate may still clog in some circumstances. For these sealants we recommend added directly to the tyre rather than through the valve and also not to remove air via the valve when the valve is at the 6 o'clock position.

      Due to the hi-flow, if the tyre are deflated with the valves at 6 o'clock the sealant may be siphoned out of the tyre. For that reason the valve should be at another position.

      Valve Rebuild

      ‘Hi Flow’ Tubeless Valves – the end of Presta?

      I fitted a pair and BAM! Well actually more a poof! I was able to seat a pair of Schwalbe X-One tyres to some Mavic Open Pro UST rims using just a track pump. It was easy, just a few strokes and up they went. So, so far the ‘Hi Flow’ valves have impressed. They stayed sealed, no leaking around the valve, I’m happy. Cytech Review

      Bike Rumour


      If you're constantly unclocking clogged Presta valves or running a tubeless setup, the 76 Projects HI FLOW 'No Clog' Tubeless Valves are an absolute must-have. Although it takes a little more to install them, they perform exactly as promised, making tyre inflation much quicker and easier at a price that's incredibly competitive to traditional tubeless valves. These valves may just spell the death of Presta.

      HI FLOW VALVE OVERVIEW

      Despite fitting in the same size valve hole and using the same pumps as presta Hi Flow valves have a unique precision CNC'd construction which enables 4x the airflow.

      HI FLOW 'NO CLOG'

      Hi Flow Valves valves feature a unique hollow precision CNC'd stainless steel valve core. In combination with the wider 'transfer chamber' section it means that 4x the air flow is achieved versus a presta valve.

      The greatly increased clearances also mean that clogging is far less likely. Whereas the clearances in a Presta valve are smaller than the holes that sealant is supposed to be able to block so it's no surprise that they get clogged.

      VALVE SIZES

      Size 0 - 09-20mm rim height* Compatible with rim inserts - MTB

      Size 1 - 15-35mm rim height* Compatible with rim inserts - MTB / GRAVEL / ROAD

      Size 2 - 30-50mm rim height* - GRAVEL / AERO ROAD

      Size 3 - 45-65mm rim height* - DEEP SECTION AERO

      Size 4 - 60-85mm rim height* - DEEP SECTION AERO

      *unlike normal valves our HI Flow valves are specified by the rim height rather than the valve length.

      ADDING SEALANT

      Sealant may be added directly through the hollow valve core via a tube with an internal diameter of 5mm. However, we always recommend unseating a section of tyre and putting sealant directly in. That way the sealant level can be observed. Because of the hi-flow nature the direct method is much easier than with presta valves.
      See video for tips on adding sealant.

      *Some sealants with very large particles such as Silca Ultimate may still clog in some circumstances. For these sealants we recommend added directly to the tyre rather than through the valve.

      PUMP COMPATIBILITY

      Our Hi Flow valves are not Presta but are designed to be work with Presta style lever lock style pump heads .
      The hi flow design means that some screw-on and push on pump heads do not fit well or at all.  We offer 2 adapter options for those pump head types:

      Adapters are available to fit Presta or Schrader style pump heads. Schrader version supplied if you select the adapter option on this page. The Schrader option is much smaller than Presta so we recommend that if your pump has Schrader head option. Separate adapters can be found on this page.

      *No adapter required for One Up EDC pump.
      **Topeak Smart Heads or others that use one opening for both Presta and Schrader will require an adapter.

      99% NO CLOG

      I have multiple bikes and all run 76 Hi Flows. Seriously, hands down better than Fillmore's. There is no valve out there that is 100% clob proof. These are pretty close to it. Every once in a great while, I have to remove the valve and unclog some of the Kevlar fibers that build at the bottom of the valve. Remove the screw top, drop the plunger out and clean. Good as NEW.

      My favorite high flow valves

      I’ve two sets of these now in use on a mtb and gravel bike. They work better than the other primary competitor, Reserve, on pumps and have similar flow and anti-clogging. I’ve never had them clog after a > 1yr now with one pair. I’ve had a few pumps that wouldn’t work that great due to the wider piece up top. robust design and set and forget…my favorite kind of parts.

      High flow valve, but should have better compatibility with pumps. I tested all of my floor and hand pumps, and none of them work without some form of an adapter. Thread-on pumps won’t work without an adapter. I had to go with regular Presta valve stems due to this. Also, I feel like the push-on caps will get lost, they just don’t feel all that secure, and due to the different thread, you can’t just use a Presta valve cap.

      These would be a lot more awesome if the threads matched Presta valves, and there was a little more length for a press-on Presta pump to hold on to.

      If they happen to actually clog, you can’t service them like a Presta valve stem, so expect a messy time as you’d have to remove the whole valve stem to service or swap out a clogged/stuck/broken valve.

      I can’t see putting these on a bike that’s going to be used for touring. The extra fussiness of carrying little adapters makes this less practical for a lightweight road setup.

      Hi, thanks for taking the time to review. The 4x greater flow cannot be achieved using the same thread a presta hence why the adapter are necessary for pumps that don't have lever lock heads. For some it's not ideal but we feel that 2x flow was not enough so made this choice.

      Cable ties

      These are very best cable ties I’ve ever used. I haven’t used the valves yet, but I’m excited to try them.
