The thread size of this bulkhead fitting (including the main body and lock nut) is AN6 9/16-18 UNF.
Forms a seal in panel/bulkhead thicknesses ranging from 1 mm to 8 mm, suitable for engine compartment/firewall penetration.
The fixed locking nut can rotate freely on the threaded body. Both sides feature hexagonal flats, enabling one-handed installation in confined spaces.
The 37°flared end fits AN specification pipes perfectly, effectively preventing fluid leakage. High-strength aluminum and anodized treatment enable it to function normally in harsh environments.
