Part number 290994 is a Panel Bracket Gauge Mount, a precision-formed metal bracket designed specifically for the PowrLiner 4955, 6955, and 8955 series airless sprayers and line stripers. This component serves as the dedicated mounting interface between the pressure gauge and the sprayer's control panel or frame assembly. The bracket positions the gauge for optimal operator visibility while protecting it from vibration, impact, and environmental contamination.
The PowrLiner 4955, 6955, and 8955 models are professional-grade hydraulic drive line stripers designed for medium to large-scale projects including airports, roads, parking lots, and athletic fields [citation:5][citation:6][citation:7]. These units feature precise pressure control from 400 to 3300 PSI, enabling operators to spray everything from light-bodied coatings to low-VOC striping paints [citation:5][citation:6][citation:7]. The pressure gauge is the primary instrument for monitoring and adjusting system pressure, making its secure and accurate mounting essential for proper operation.
This bracket is subjected to continuous vibration from the hydraulic drive system and gas engine, as well as exposure to weather, cleaning solvents, and road debris during transport and operation. Failure modes include stress cracking at mounting points, deformation from impact or overtightening, corrosion of the bracket material, and fatigue failure of the gauge retaining features. A damaged or missing gauge mount can allow the pressure gauge to vibrate excessively, shift position, or detach completely, resulting in inaccurate pressure readings, operator distraction, and potential gauge damage.
| Secure Mounting | Provides stable attachment point for pressure gauge to control panel or frame |
|---|---|
| Vibration Isolation | Reduces transmission of engine and hydraulic system vibration to sensitive gauge mechanism |
| Operator Visibility | Positions gauge for optimal viewing angle during operation |
| Physical Damage | Bracket is bent, cracked, or has broken mounting tabs |
|---|---|
| Corrosion | Severe rust or chemical degradation has compromised structural integrity |
| Fatigue Failure | Cracks at stress points from continuous vibration during operation |
| Gauge Instability | Pressure gauge is loose, vibrates excessively, or has shifted from proper position |
Part number 290994 is specifically designed for the PowrLiner 4955, 6955, and 8955 models. These hydraulic drive line stripers share common platform architecture including the epoxy-finished frame, SmartArm™ gun mount system, and precise pressure control from 400 to 3300 PSI [citation:5][citation:6][citation:7]. This panel bracket gauge mount is a model-specific component engineered for these particular sprayer systems. Always confirm fitment using the correct parts diagram for your exact model and serial number.

The gauge mount bracket is part of the sprayer's pressure monitoring and control system. When servicing this component, these related parts are often inspected or replaced at the same time.
The 0-3300 PSI pressure gauge that displays system operating pressure. Should be inspected for accuracy and lens condition.
The valve or fitting connecting the gauge to the hydraulic system. Check for leaks and thread condition.
Screws, nuts, and washers securing the bracket to the control panel. Replace if corroded or damaged.
