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.

We hate it went a product has to be junked when a part can't be replaced. If spares aren't listed email us and we'll see if we can help.
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 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.

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