NPT threads are widely used in automotive applications; however, they are not intended for repeated maintenance. HPS AN to NPT adapter fittings convert NPT female thread ports to AN-style fittings, facilitating easier maintenance. AN-style fittings can be installed and removed multiple times without additional sealant or gaskets, whereas barbed fittings or clamp-secured hoses can be damaged by repeated use. HPS AN to NPT adapters are made of 6061 aluminum with a Type II black anodized finish for increased wear and corrosion resistance.
Before You Order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Compatibility Check
As our entire product database is based on North American vehicles (USDM), please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our home page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping fees are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare instances where there is a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection system" (Shaken), and we are unable to provide strength study documents or similar for that purpose. Therefore, all parts are sold for use on "circuits, private property, and off-road" use, and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging boxes or products. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
