Socket head plug for Terex PT80

The 0301-103 socket head plug is a specialized sealing component used to close off unused ports or inspection openings in hydraulic blocks, housings, or fluid reservoirs. It features a 3/8-18 NPT tapered thread, which ensures a secure seal when tightened into the corresponding port. The socket head design allows for installation and removal using a standard hexagonal key, making it suitable for use in confined spaces where traditional wrench access may be limited. By effectively sealing these openings, the plug prevents fluid leaks and keeps contaminants from entering the internal systems of the machine.

This component is specifically utilized within the undercarriage assembly of the Terex PT80, applicable to units with serial numbers DTI 01310 and later. Plugs of this type are standard in heavy machinery to maintain the integrity of pressurized fluid systems, such as hydraulic lines or lubrication circuits. Proper installation ensures that the system remains closed and protected from external debris, which is necessary for the consistent operation of the machine's mechanical assemblies.
