Socket Weld & Thredaed Hex Plug, Square Head Plug, Bull Plug Suppliers
A hex plug features a hexagonal head, making it easy to tighten or loosen using a wrench, ensuring a secure seal for pipe ends or threaded openings. Made from high-quality materials such as stainless steel, brass, or carbon steel, hex plugs are commonly used in plumbing, mechanical, and automotive systems.
Square plugs, with their square-shaped heads, are ideal for applications requiring a secure seal that can be easily tightened or removed with a wrench or socket. These plugs are often used in industrial systems, including oil and gas pipelines, and offer robust sealing solutions, especially when space constraints make other plug types difficult to install.
Bull plugs, characterized by their large, round, and often heavy-duty design, are specifically designed to seal larger pipe openings. They are typically used in high-pressure systems and come in various materials to withstand tough environmental conditions, such as extreme temperatures and corrosive environments. Bull plugs provide a tight, reliable seal, ensuring system integrity and preventing leaks or contamination.
