Specification
Description
The Performance Fittings O-Ring Plug (PRF3723BLK) threads into an unused -4 AN O-ring boss port to seal it off. Manufactured from aluminum and finished in black anodized coating, it keeps dirt, moisture, and debris out of an unused port on a fuel cell, block, or fitting.
The included O-ring seals metal-to-rubber against the boss face, so no thread sealant is needed — just torque to spec for a leak-free seal.
