Game changer! The Quick Fill Plasma Valve connects directly with the sealant bottle tube for direct injection after mounting the tire, resulting in mess free installation. The Valve allows riders to add sealant without breaking the tire bead, and without the need for tools! Other Key Features: Resists build up and prevents sealant from clogging and congealing at the valve. No more sticky mess! Oversize stem allows for high volume flow, ease of inflation and pressure adjustment. Two-piece body and removable valve enables easy cleaning to maintain optimal performance. CNC machined. Aluminum construction.
