- IMPORTANT - this is an "open flow" air chuck for Presta valves. This chuck MUST be used as an attachment to an inline tire inflator tool (or) 12-volt portable air compressors. If your compressor has an air tank, you must first attach this chuck to an inline tire inflator gauge that accepts 1/4 inch NPT attachments.
- Patented Self-Locking - rapidly locks on to the Presta valve stem on your bike tire thanks to our patented "push-to-lock" technology, providing an airtight seal that won't leak or fail. No more fighting the valve stem for a proper seal.
- "No Loss" Quick-Release - quickly disconnect air chuck from the bike tire Presta valve with absolutely zero measurable air loss.
- Multi-Functional - the 1/4" F-NPT female threaded end of the tire chuck connects to hand-operated tire inflator tools for inline connection to your air compressor. The Presta head also features 1/8 inch M-NPT threads that can be directly attached to the air hose nozzles of 12-volt portable compressors (see product images).
