4B series hex plug is standard BSP male thread 60° cone sealing blanking plug, used for blocking redundant ports of hydraulic manifolds and pipeline ends. Integral hot forging plus precision CNC turning ensures compact solid structure; 60° metal cone forms tight metal-to-metal seal after torque tightening without extra sealing compound. Available with two anti-corrosion surface treatments, the burr-free precise BSP threads realize smooth gall-free assembly and long-term leakproof performance against system vibration and frequent pressure fluctuation. Widely applied to block spare ports of machinery hydraulic loops and pneumatic pipelines for oil, water and compressed gas conveying.
60° Cone Metal Hard Seal Design: Wedge-type cone structure forms stable metal-to-metal compression seal during tightening, no O-ring or sealant required, excellent leakproof performance under high temperature and pressure surge.
Standard Hex Wrench Head: Standard outer hex structure matches common open/box wrench, convenient torque control and quick on-site installation without corner slipping or rounding damage.
Anti-Galling Smooth Precision Thread: Burr-free CNC machined BSP male threads guarantee smooth screwing, support repeated disassembly and maintenance without thread scratch or galling deformation.
High-Density Forged Anti-Vibration Body: One-piece hot forging eliminates inner porosity of casting, improves integral compression and fatigue resistance to avoid plug loosening under long-time equipment vibration.
Multi-Media Universal Matching: Stable material and sealing performance fit petroleum hydraulic oil, water glycol and various industrial compressed gas blocking requirements.
Environment-friendly trivalent chromium zinc coating with uniform tight adhesion and reliable salt spray & anti-rust property, high mechanical strength and cost advantage. Preferred choice for construction machinery, agricultural equipment and general indoor hydraulic pipeline blanking.
Professional passivation removes surface free iron and machining residues to form compact self-repair oxide film, outstanding acid, alkali and salt fog resistance, suitable for marine, petrochemical and high-corrosion severe working environments.
Construction & Agricultural Machinery: Spare port blocking for hydraulic manifold of excavators, loaders, tractors and harvesters.
Mining Equipment: Pipeline end blanking plug for underground mining machinery high-vibration hydraulic circuit.
Petrochemical & Marine: Stainless steel version for chemical factory medium pipeline and offshore platform fluid system redundant hole sealing.
General Industrial Hydraulics: Blank unused ports of hydraulic power unit, pneumatic control valve block and automated production line pipeline.
Raw blank is integrally hot forged to optimize internal metal grain distribution for denser texture and higher burst resistance. BSP male thread, 60° sealing cone and outer hexagon are finished synchronously by multi-axis CNC lathe to guarantee accurate dimensional tolerance. All finished plugs go through thread calibration, sealing pressure test and full appearance inspection before warehousing.
Q1: Does this BSP plug need raw material tape when installation?
A1: Rely on 60° cone metal hard seal normally without auxiliary sealant; wrap a small amount of PTFE tape for ultra-high pressure working condition as needed.
Q2: Can it replace imported same specification BSP plugs directly?
A2: Produced in strict accordance with standard BSP thread and 60° cone size, direct drop-in replacement without modifying hole size.
Q3: Can laser marking be customized on hex surface?
A3: Yes, we support laser engraving customer’s exclusive logo and part number after receiving vector drawing file.
Q4: How to select material for coastal salt fog environment?
A4: Passivated stainless steel is recommended for coastal and chemical corrosive environment; zinc-plated carbon steel is used for conventional indoor non-corrosive working scene.
