Part number 296270 is a Packing Seal Assembly, a precision-engineered sealing component designed for the Airless1 G10, Airless G10, Airless G10 TR2, and Airless LX-65 Spray Guns. This assembly forms the primary high-pressure fluid seal within the gun body, containing material pressures up to 3600 PSI and preventing leakage past the trigger valve mechanism. The packing seal assembly ensures that all fluid is directed forward through the spray tip only when the trigger is engaged, providing instant start and positive shut-off without drips or creeping material.
Constructed from specially formulated materials resistant to solvents, water-based coatings, and abrasive pigments, this seal assembly withstands the extreme pressures and chemical exposure of daily professional use. The packing seal works in conjunction with the ball and seat assembly to create a positive shut-off valve. When the trigger is released, the spring-loaded mechanism forces the ball against the seat while the packing seal prevents any material from bypassing around the piston. This dual-seal system is essential for clean operation, material savings, and operator safety.
This seal assembly is a routine maintenance item subject to wear from continuous cycling, abrasive material flow, and chemical degradation. Symptoms of a worn packing seal include material weeping from the trigger area, difficulty achieving clean shut-off, creeping spray tips, and internal bypass causing pressure loss at the gun. Replacement with genuine 296270 packing seal assembly restores proper gun function, eliminates leaks, and ensures safe, reliable operation. Always perform pressure relief procedure before servicing and lubricate new seals during installation with compatible gun lubricant.
| High-Pressure Containment | Seals fluid pressures up to 3600 PSI within the gun body |
|---|---|
| Trigger Shut-Off | Prevents material bypass when trigger is released for clean starts and stops |
| Leak Prevention | Eliminates fluid seepage from trigger area and body joints |
| Trigger Leakage | Fluid weeping or dripping from trigger pivot area during operation |
|---|---|
| Poor Shut-Off | Gun continues to drip or spray briefly after trigger release |
| Pressure Loss | System pressure drops when gun is triggered off |
| Preventive Maintenance | Replaced during annual overhaul or when other internal seals are serviced |
Part number 296270 is specifically designed for the Airless1 G10, Airless G10, Airless G10 TR2, and Airless LX-65 Spray Guns. These professional airless spray gun models share a common internal fluid section design and utilize identical packing seal assemblies. This seal assembly is a model-specific component engineered for the pressure ratings and dimensional requirements of these particular spray guns. Always confirm fitment using the correct parts diagram for your exact model.

The packing seal assembly is one component of the gun's complete fluid control system. When servicing internal seals, these related parts are often inspected or replaced at the same time.
The check valve assembly works directly with the packing seal. Worn ball or seat will cause leaks and pressure loss.
The small seal inside the tip guard prevents leaks around the spray tip. Often replaced during complete gun service.
The internal filter protects the packing seal and tip from debris. Clean or replace during seal replacement.
