PowrTwin part 191-211 is a Hex Bushing used to adapt threaded connections between different pipe or fitting sizes within the fluid system. When the bushing becomes cracked, corroded, or develops leaks, pressure integrity is compromised and material waste occurs. This replacement bushing restores proper thread adaptation and leak-free sealing on compatible PowrTwin and PowrLiner units.

The PowrTwin 191-211 Hex Bushing is a precision threaded adapter designed to connect fittings or pipes of different sizes within the fluid system of sprayers and striping machines. On compatible equipment including the PowrTwin TM 8900 XLT, 12000 XLT, 6900 XLT, 4900 XLT, and the 4900, 6900, 8900, 12000 Plus series, as well as PowrLiner 6950_1, 6950, 4950, and 4955, 6955, 8955 models, this hexagonal bushing reduces or increases thread size, allowing components with mismatched ports to be connected securely. The hex shape provides wrench flats for easy installation and removal, even in confined spaces. A cracked, corroded, or damaged bushing allows fluid to escape under pressure, causing external leakage, pressure drop, and material waste. Stripped or cross-threaded bushings prevent proper tightening, leading to progressive leakage or fitting blowout. Over time, exposure to solvents, pressure cycling, and vibration can cause bushing materials to fatigue, develop stress cracks, or seize to mating fittings. Replacing a damaged hex bushing restores proper thread adaptation, eliminates external leakage, and prevents progressive damage to adjacent components such as pumps, valves, hoses, or manifolds. This genuine PowrTwin replacement bushing meets original equipment specifications for material composition, thread type, pressure rating, and dimensional accuracy. When installing a new bushing, clean mating threads thoroughly, use appropriate thread sealant or tape compatible with your coating, and torque to manufacturer specifications using the hex flats for wrench application. Users should always verify compatibility with their specific model and revision before installation. Regular inspection of bushings for signs of cracking, corrosion, or thread damage should be part of preventive maintenance programs.
| Thread adaptation | Reduces or increases thread size between different fittings |
|---|---|
| Leak prevention | Provides sealed connection under operating pressure |
| Easy installation | Hex flats allow wrench tightening in confined spaces |
| External leakage | Fluid weeping or spraying from bushing threads or body |
|---|---|
| Visible damage | Cracks, corrosion, stripped threads, or deformed shape |
| Thread seizure | Bushing cannot be removed or installed due to galling |
| Connection failure | Unable to achieve proper seal despite correct installation |

Threaded connection problems are often caused by more than one component. When servicing the hex bushing, these parts are commonly inspected at the same time.
Damaged threads on the fitting that connects to the bushing may require replacement.
Dried, incorrect, or missing sealant prevents proper sealing and may cause leakage.
Damaged threads in the pump, valve, or manifold port may require repair or replacement.
