High Speed Needle O-Ring (Red) (2) by REDS Racing
This product was added to our catalog on March 15, 2013.
This is a pack of two replacement REDS Engines High Speed Needle O-Rings. These are compatible with the REDS R5, R5C, R5T and R5TE engines. REDS engines use a dual o-ring needle, with a red o-ring in the upper position, and a black o-ring (REDES216070) in the lower position. These are the red upper position o-rings.
These O-Rings are used to seal the high speed needle. When you make an adjustment to the HSN and it feels loose, it is a good idea to change the O-Rings to prevent possible air leaks.
