Hi, there! No, this Oatey 39176 tubing connector doesn't come with a locknut. You have to purchase the Oatey 38829 locknut separately. To order the nut, please contact one of our knowledgeable customer service representatives @ 435-868-4020 between 8:00 AM and 7:00 PM MT or through e-mail @ firstname.lastname@example.org. If you're ready to place an order for the tubing connector, just simply click on Add to Cart and enter your information in the required fields. We hope that this helps.
