M3 x 0.5 x 6 Cap Stainless Steel

M3 x 0.5 x 6 stainless steel cap (plug) for the shift valve block. This small cap seals unused ports or access holes in the valve block, maintaining system pressure and preventing leaks or contamination.

The valve block contains multiple ports for air lines, sensors, and other connections. Some ports may be unused depending on the system configuration, and these caps seal those ports to maintain system integrity. The stainless steel construction provides excellent corrosion resistance for the pneumatic shift system.

Used throughout the valve block assembly where ports need to be sealed. The 6mm length provides sufficient thread engagement for a secure seal. Always torque to manufacturer specifications—overtightening can damage threads in aluminum components.

This is an OEM replacement part that comes standard with the Rush SR air shifter system. Sold individually.
