The Snow Performance -4AN bulkhead Teflon washer is a precision sealing component for -4 AN fittings used in fuel, oil or coolant line installations. Constructed as a Teflon bulkhead washer, it offers a stable, non-reactive sealing surface for panel pass-throughs and helps maintain leak-free connections in fabrication and plumbing tasks without adding metallic abrasion at the bulkhead interface.
