TracTuff M20 to -10 AN Male Flare Fitting

The TracTuff M20 to -10 AN Male Flare Fitting is a high-quality adapter designed to make plumbing your Honda engine’s auxiliary systems clean and reliable. This fitting allows you to connect aftermarket lines or accessories using the M20 x 1.0 port commonly found on many Honda and Acura cylinder heads. Whether you’re working on a K-Series PRB, PRC, PPA, or PPL cylinder head, or setting up custom plumbing under the VTEC Spool Valve on B and H series engines, this fitting provides the perfect solution for a precise and secure connection.

Machined from high-grade aluminum and finished for durability, the TracTuff M20 to -10 AN Fitting gives enthusiasts the flexibility to run custom oil or coolant lines. It’s a must-have component for custom builds or race applications that require additional fittings without sacrificing reliability or OEM-level fitment.

Please note that the M20 x 1.0 thread does not seal on its own. Just like the factory fitting, TracTuff recommends using Loctite 5452 as a fast-cure thread sealant or Loctite 561 if a longer cure time is available. Apply the sealant thoroughly into the threads to ensure a proper, leak-free installation.
