Is there a particular tool to install these fittings?

Asked by ROY on May 02, 2018


Thank you for your question. Dorman 56358 NPT to Nipple fitting does not require any special tools for installation. A larger enough flat head screwdriver or a standard of channel locks will help to complete the installation.
