RFX Sport Rubber Valve Seals (Red) — Pack of 2
Pack of two rubber valve seals from RFX, part of the Sport series. Designed to ensure a tight seal around the valve stem, these seals minimize air loss at the valve/rim junction and facilitate inflation and pressure checks. Their red color allows for quick identification during pre-ride inspections.
Ideal for off-road riders and mechanics looking for a simple and visible replacement part, these seals are suitable for standard valve configurations. Before installation, check compatibility with the diameter and profile of your valve stem and rim. Examples of use on recent motocross bikes: STARK FUTURE VARG EX (2026), BETA RR 250 2T (2024), STARK FUTURE VARG (2026) — to be verified against original equipment.
Installation and maintenance: quick replacement during a tire change or valve service. Regularly check the condition of the seals to maintain good sealing and reliable inflation during your rides.
