Key Features
✅ Reliable Sealing—Robust construction, tight fit with internal thread ports, providing a durable and effective end-face seal.
✅ Safe Rounded Edges – The edges are smoothly chamfered, eliminating sharp corners and preventing cuts to hands or pipelines during installation and disassembly, ensuring safer use.
✅ Long-Lasting Corrosion Resistance – The uniform and dense blackened surface layer provides excellent corrosion and rust resistance, extending service life.
✅ Robust and Durable – The malleable iron material gives it high mechanical strength, good impact resistance and pressure resistance, suitable for various working conditions.
✅ Versatile and Convenient – The standard thread design is suitable for sealing unused ports of various valves, tees, elbows, and other pipe fittings, simplifying installation and disassembly.
Application Areas
• Permanent sealing of pipeline system ends or reserved ports • Temporary closure of testing or spare interfaces of valves, tees, heat exchangers, and other equipment • Port protection of hydraulic and pneumatic pipelines • Protection of building and industrial pipelines during construction and maintenance
Quality Commitment Our products are manufactured in strict accordance with relevant standards, undergoing dimensional accuracy, thread testing, and surface quality inspection to ensure reliable sealing and consistent quality. We provide stable and reliable products to protect every end of your pipeline system.
Installation Recommendations: During installation, wrap an appropriate amount of Teflon tape or apply sealant to the threaded part of the plug, and tighten it evenly with a suitable tool until secure. For disassembly, utilize its smooth edges for safer and easier operation.
