Original TTI Industries spare part - HIGH-PRESSURE HOSE Part number: 5131045657

The RYOBI High-Pressure Hose (Part Number: 5131045657) is an authentic, original equipment manufacturer (OEM) replacement part specifically engineered for Ryobi's outdoor power cleaning lineup.

Below is a detailed overview of its technical specifications, compatible applications, and proper operating guidelines.
Technical Description and Compatibility

This pressure hose is a heavy-duty structural component engineered to withstand the intense pressure spikes generated by the pressure washer's pump assembly, safely channeling the water flow directly to the spray gun trigger.

    Primary Compatibility: It is the native replacement hose designed for the RYOBI RY170PWA pressure washerS (the high-performance 170 BAR model).

• 5133005373 4000475885 - RY170PWA - RY170PWA 170BAR PRESSURE WASHER IN2
• 5133005374 4000475886 - RY170PWA - RY170PWA 170BAR PRESSURE WASHER GB2

    Materials: Constructed from high-grade polyurethane or a reinforced rubber compound featuring an internal high-tensile textile or metallic braided sleeve. This prevents structural expansion (ballooning) under load and provides superior abrasion resistance against rough outdoor surfaces.

•     Connectors: Equipped with heavy-duty quick-connect fittings or threaded couplings (depending on the specific machine serial range, such as the 4000475886 series) engineered to ensure a watertight seal, preventing pressure drops or air leaks.

Key Applications (Intended Use)

This hose enables users to carry out the full range of heavy-duty domestic and semi-professional outdoor cleaning tasks for which the RYOBI RY170PWA was built. Leveraging the machine's 170 Bar pressure output, it is used for:

•     Vehicle Detailing: Deep cleaning cars, motorcycles, RVs, vans, and bicycles—effectively blasting away mud and road grime from wheel wells and undercarriages.
•     Driveway and Patio Maintenance: Stripping away moss, mold, lichen, and deeply embedded dirt from stone pathways, concrete, interlocking pavers, terraces, and balconies.
•     Wall and Fence Washing: Efficiently removing cobwebs, peeling debris, and accumulated grime from brick boundary walls, wrought iron railings, and gates.
•     Garden Furniture and Tool Cleanup: Seasonal washing of plastic or wooden patio sets, planters, barbecues, and lawn care equipment.

Operation and Installation Guide
1. Setup and Connection

•     Ensure the pressure washer is turned off and completely disconnected from the power source.
•     Insert one end of the hose into the pump's high-pressure water outlet until you hear a distinct "click," indicating it is securely locked (or screw the collar tightly if your model utilizes a threaded connection).
•     Connect the opposite end into the quick-connect inlet at the base of the spray gun handle.

2. During Operation

•     Uncoiling: Fully uncoil the hose before turning on the machine. Kinks or sharp bends can restrict water flow, causing water hammer effects or sudden drops in pressure.
•     Mobility: Never pull or drag the pressure washer unit by tugging on the high-pressure hose. Always move the machine using its built-in transport handle.

Maintenance and Safety (Maximizing Lifespan)

    Temperature Control: Do not feed water through the hose that exceeds the maximum temperature rating stated in the manual (typically 40°C–50°C / 104°F–122°F). Keep the hose clear of hot surfaces, such as vehicle exhaust pipes.

    Post-Operation Decompression: This step is critical. After turning off the pressure washer and shutting off the water faucet, always squeeze the spray gun trigger to release the trapped residual pressure before disconnecting the hose. Disconnecting a pressurized hose can damage the sealing O-rings or cause personal injury.

•     Storage: Store the hose without bending it at sharp angles. Loosely loop it in wide circles on the pressure washer's dedicated hose hook or reel, keeping it protected from extreme winter freezing temperatures.
