Description
125# Leaded Brass Square Countersunk Plug
125# Leaded Brass Square Countersunk Plugs are threaded closure fittings designed to seal compatible female-threaded openings while maintaining a low-profile exterior. The countersunk square-drive configuration allows the plug to sit more flush with the surrounding fitting or component than an external square-head plug.
This product is identified as a 125# leaded brass fitting. Manufacturer dimensional, certification, and material safety documentation is provided below for reference.

Square Countersunk Plug Construction
A square countersunk plug uses male threads to close a compatible female-threaded fitting, valve, manifold, or equipment port.
Unlike a square head plug with an external wrenching head, the countersunk design uses an internal square drive. This creates a lower-profile installation and can be useful where clearance around the fitting is limited.
The threaded construction provides a removable closure that can be reopened later for maintenance, inspection, or system modification.
