NPT threads are widely used in automotive applications, but they are not intended for repeated maintenance. HPS AN to NPT adapter fittings convert NPT female threaded ports to AN-style fittings to facilitate easy maintenance. AN-style fittings can be installed and removed multiple times without the use of additional sealants or gaskets, whereas barbed fittings or clamp-secured hoses may become damaged after repeated use. HPS AN to NPT adapters are made from 6061 aluminum with a Type II black anodized finish for increased wear and corrosion resistance.
Before Ordering
〇 Regarding Import Consumption Tax
At the Shaft-ya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
All product databases are based on North American vehicles (USDM). Please confirm whether or not parts can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If an order is placed without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, this does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All product information has 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 costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient 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 via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for the purpose of Japanese inspections. Therefore, all parts are sold for "circuit, private property, or off-road use" purposes, and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your package as soon as it arrives. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
