Ensure your PowrTwin 3500 sprayer stays reliably fed and clog-free with our genuine Syphon Hose Assembly parts. This sub-category covers the suction hose and foot-valve assembly that draw coating material from the supply container into the pump system—critical for maintaining optimal throughput, avoiding air inclusion and ensuring consistent spray performance.

Why Choose Genuine Syphon Hose Assembly Parts?

Designed specifically for the PowrTwin 3500 series—made to the correct length, diameter and fitting spec for your machine.
Enables proper material feed: a correct syphon hose prevents air leaks, ensures full stroke efficiency and reduces erratic pump behaviour.
Uses quality components like the foot‐valve and rock catcher (for bulk containers) to protect the pump from debris and prolong component life.
Genuine parts assure proper threading, seal tape application (as per manual) and compatibility with the rest of the system.
Reduces downtime: improper or worn syphon hoses are frequent causes of prime/fill issues, inconsistent spray output or pump cavitation.

Our Range of Syphon Hose Assemblies

Here are typical items you’ll find in this sub-category (each item should link to its product page for full specs and ordering):

Rock Catcher Assembly + Hose – Part # 103-826 (Includes hose, hose clamps, tube, filter screen, adapter & spring)
Siphon Tube / Bent Tube – Part # 103-550 (support component for suction feed)

Pro Tip: When you experience slow build-up of pressure, frequent priming issues, or uneven strokes on the pump, inspect the syphon hose assembly first—air leaks, damaged hose or clogged rock catcher are often the underlying cause.

How to Choose the Right Syphon Hose Assembly Part

Here’s how to select the correct part for your PowrTwin 3500:

Identify the usage scenario: If you’re drawing from a large 55-gallon drum, use the 1″ × 6-½′ version; for 5-gallon or small containers, the shorter ¾″ version may suffice.
Confirm your model and year: Ensure your sprayer is a PowrTwin 3500 and check whether your feed application matches the assembly spec. The manual notes, “The siphon hose and the bleed line hose have factory-installed tape on the male end of the hoses. Tighten the syphon hose… wrench tight.”
Decide full assembly vs replacement part: If the hose is intact but the foot valve or rock catcher is faulty, you may only replace that component. If the hose is kinked, cracked or excessively worn, replace the full assembly.
Follow correct installation: As the manual emphasises, use factory-installed PTFE tape, avoid thread sealants on the syphon hose assembly, ensure the suction hose is fully submerged in material, and prevent air ingress.
Maintain regularly: Check for hose integrity, clamps, foot valve function, and cleanliness of the rock catcher to maintain prime and suction efficiency.

FAQs

What does the “Syphon Hose Assembly” category cover for the PowrTwin 3500?

This category covers the suction feed components of the PowrTwin 3500—namely the syphon hose, rock catcher, foot valve, siphon tube, and related hardware used to draw coating material into the pump system.

Why do I need a specific syphon hose assembly rather than a generic hose?

Because the PowrTwin 3500’s fluid pump and suction path demand precise hose dimensions, end fitting specs, priming, and seal characteristics. Generic hoses may allow air leaks, wrong flow rates or improper foot valve seating, resulting in pump performance issues.

How do I know if I need to replace the syphon hose assembly?

Signs include difficulty in priming, uneven strokes ofthe pump, frequent cavitation or loss of suction, visible hose damage (kinks, cracks), a foot valve that fails to maintain prime, or when the hose length/diameter is incorrect for your material feed setup.

Can I just replace the foot valve and keep the hose?

Yes, if the hose is in good condition and the only issue is the foot valve, you can replace just the foot valve. However, if the hose has visible wear, leaks, or an incorrect dimension for your feed situation, replacing the entire assembly ensures optimal performance.

How should I install the syphon hose assembly properly?

Install by submerging the suction end in the material container, ensuring the foot valve seats correctly, use PTFE (“37)(” as per the manual) tape on male threads of the hose end, tighten wrench-tight, avoid thread sealant, avoid air leaks in the connection, and follow the manual’s “Connecting the Hoses” steps.
