Wholesale PricingThe 1/2" x 3" Black Pipe Nipple is the engineering standard for routing high-pressure compressed air and pneumatic control lines in manufacturing environments. Manufactured from high-tensile Schedule 40 carbon steel, this 3-inch extension provides the ideal mid-reach for clearing industrial structural headers or mounting air-driven assembly tools to a main distribution header.
The black oxide finish provides a high-friction surface for high-torque installation, ensuring the fitting can withstand the constant mechanical vibrations and pneumatic pressure surges common in heavy-duty factory settings. With precision-machined male NPT threads, this nipple creates a reliable metal-to-metal interference fit, serving as a dependable bridge for compressed air manifolds where air-tight integrity is a critical operational metric.

| Pressure Rating | 150 PSI WOG / 300 PSI Static |
| Wall Schedule | Schedule 40 (Standard Wall) |
How does the 3" length affect pneumatic manifold spacing?
The 3-inch nipple is specifically sized to provide clearance for industrial pressure regulators and moisture traps. This mid-reach length allows technicians to install or service secondary pneumatic drops without the components interfering with the primary air header or support brackets.
Can I use a 3" black nipple for pneumatic sensing lines?
Yes. The 1/2" NPT interface is a standard for industrial actuators and sensing equipment. The structural rigidity of ASTM-grade carbon steel ensures the sensor remains stable even under the high-vibration conditions found near reciprocating compressors or stamping presses.
Is this 3" extension compatible with air-driven tools?
Absolutely. This nipple is a staple for building rigid drop line manifolds for impact wrenches and assembly line tools. Unlike flexible hoses, the Schedule 40 pressure boundary provides a permanent, non-degrading path that resists the internal heat and lubricant aerosols found in industrial air systems.
