Key Features

Converts existing metric threads to male 37-degree AN flare for easier maintenance.

Metric fittings are widely used in automotive applications, but they require the washer to be replaced during repeated maintenance to prevent leaks. HPS AN to Metric adapter fittings convert female metric threads to AN-style fittings, allowing for easy and repeated maintenance. AN-style fittings can be installed and removed multiple times without the need for additional sealant or gaskets. HPS AN to Metric adapters are made from 6061 aluminum with a Type II black anodized finish for improved wear and corrosion resistance.
Before Ordering
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 are no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Our product database is based on North American vehicles (USDM), so please verify whether parts will fit Japanese vehicles (JDM) before placing your order. (Please feel free to contact us if you are unsure whether a listed product fits your vehicle. 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, make, and model on our homepage tabs, 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 costs are paid at the time of payment. Shipping estimates are calculated automatically once you enter your shipping 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.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when placing an 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 never shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar paperwork for this purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-public roads," 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 the products themselves. Please understand that we will only provide returns, refunds, or replacement items for damaged, defective, or incorrect products if you contact us within 7 days of receipt. Also, please note that for products sold through our company, all warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
