Detailed Product Description

The Dorman 785-070D pipe plug is manufactured from solid brass, providing excellent durability and corrosion resistance in automotive environments. Its fine outside threads (1/8 inch MNPT) ensure a secure and leak-free fit in threaded ports. The square head design allows for easy installation and removal using standard tools sized at 0.27 inches. With an overall length of 0.58 inches and a thread diameter of 0.58 inches, this pipe plug meets SAE specifications and is suitable for use in various fluid and air systems.

This pipe plug is designed specifically for use in Ford and Mercury vehicles such as the Aerostar, Bobcat, Bronco II, Capri, Mustang, Pinto, and Ranger models. The regular grade brass material is not heat hardened or zinc coated, making it ideal for applications where moderate strength and corrosion resistance are required.
