NPT threads are widely used in automotive applications. However, they are not intended for repeated servicing. HPS AN to NPT Adapter fittings convert your female NPT threaded ports to AN style fitting for easy serviceability. AN style fittings can be installed and removed many times without using any additional sealants or gaskets, whereas barbed fittings and clamped-on hoses can be damaged after repeated use. HPS AN to NPT adapters are made from 6061 aluminum and Type II anodized black to provide improved abrasion and corrosion resistance.
