3" 2,000 PSI Fig 206 Tapped Male Blind Sub with Wing Nut (1/2" NPT) – Oil & Gas Hammer Union
Verfügbarkeit für Abholungen konnte nicht geladen werden
The 3" Figure 206 Tapped Male Blind Sub with Wing Nut and a 1/2" NPT port is a highly versatile, medium-pressure closure assembly designed to securely cap off female threaded hubs while providing an integrated access point for critical instrumentation. Rated for a Cold Working Pressure (CWP) of 2,000 PSI, the Figure 206 series is specially designed with a secondary O-ring seal to ensure a bubble-tight, leak-proof connection in systems carrying air, water, oil, or gas.
Manufactured from high-strength forged steel, this complete assembly includes the precision-machined male blind sub (featuring the O-ring groove) and the heavy-duty Figure 206 wing nut. The central 1/2" National Pipe Thread (NPT) tap allows rig personnel to seamlessly install pressure gauges, transducers, or small-bore needle valves directly onto the terminal end of the flowline. This setup enables operators to monitor trapped line pressure or safely bleed off hazardous fluids before breaking the hammer union, maximizing operational safety.
Built to endure the rigors of standard-duty oilfield environments, the 3" 206 Tapped Male Blind Sub ensures robust fluid containment, vibration-resistant sealing, and simplified manifold management.
Features & Benefits
