Quincy Compressor 111151-003 Adapter

The Quincy Compressor 111151-003 Adapter is a high-grade brass compressor fitting designed for tight-tolerance performance in industrial compressed air systems. Engineered as a genuine Quincy replacement part, this M012XF025 "Fit P" adapter provides a reliable transition point within your discharge or control lines, ensuring leak-free operation under high-vibration conditions common in reciprocating air compressors. As an OEM compressor adapter, it eliminates the sizing inconsistencies often found with generic aftermarket fittings, maintaining the integrity of your factory NPT thread connections.

For contractors performing air compressor maintenance or rebuilds, using this corrosion-resistant brass adapter is critical for preventing pressure drops and downstream contamination. This component is specifically fabricated to handle the thermal cycling of heavy-duty pumping units, making it an essential stocked item for reducing system downtime. Whether you are servicing a QSI, QT, or QTS series unit, the 111151-003 offers the precise fit required to meet original technical specifications and optimize pneumatic flow efficiency across the entire compressor pump assembly.

• Durable Brass Construction: Resists oxidation and mechanical fatigue in high-heat environments.
• Precision Threading: Ensures a secure, metal-to-metal seal to prevent energy-wasting air leaks.
• OEM Compatibility: Guaranteed fit for Quincy reciprocating and rotary screw configurations.
• Ease of Installation: Standard hex design allows for straightforward torquing with standard field tools.

• What does "Fit P" refer to? This is a Quincy-specific size and geometric designation ensuring the adapter mates correctly with proprietary internal housing ports.
• Can this be used on non-Quincy machines? While it uses standard NPT-compatible threads, it is optimized for the port depths and clearances of Quincy Compressor units.
• Is brass better than steel for this application? Yes, the brass composition offers superior sealing properties and resistance to the moisture found in compressed air lines.
