Titan 704-079A Syphon/Bypass Hose Assembly

Titan 704-079A Syphon/Bypass Hose Assembly

Sourced From:
Titan Tools Inc.

 

Titan part 704-079A is a syphon/bypass hose assembly that directs paint flow from the syphon tube back to the pump inlet or paint container during priming and pressure relief. This assembly helps maintain steady material supply, reduces air entrapment, and ensures proper recirculation on compatible PowrLiner units.

Syphon/Bypass Hose Assembly for PowrLiner 1800M & 2800M

The Titan 704-079A Syphon/Bypass Hose Assembly is a genuine replacement part designed to restore proper paint recirculation and priming function on PowrLiner 1800M and 2800M airless line stripers. The assembly includes both the syphon hose (draws material from the container) and the bypass hose (returns excess paint to the container or pump inlet).

Over time, original hoses can become brittle, cracked, clogged, or loose at the fittings, leading to poor priming, inconsistent spray pattern, or loss of pressure. Replacing the complete assembly restores reliable material flow and reduces downtime.

Service Guidance: If your PowrLiner struggles to prime, spits air frequently, or the bypass flow is weak, inspect the syphon and bypass hoses for cracks, kinks, or loose clamps before replacing the pump or packings.

What it does and when to replace it

What the syphon/bypass assembly does
Syphon function Draws paint from the container into the pump inlet
Bypass function Returns excess paint during priming or pressure relief to prevent deadheading
Air elimination Helps purge trapped air from the system for consistent spray
When replacement is recommended
Cracks or leaks Visible paint seepage or air suction leaks
Hard / brittle hose Loss of flexibility, kinking, or difficulty fitting onto barbs
Clogs or restrictions Reduced flow even after cleaning the strainer
Poor priming Pump runs but will not draw material; bypass valve test fails

Compatibility

Titan part 704-079A is compatible with the following models. Always verify with your machine's parts diagram, as revision levels may vary.

Brand / Model Component
PowrLiner 1800M Syphon/Bypass Hose Assembly
PowrLiner 2800M Syphon/Bypass Hose Assembly

Related parts commonly serviced together

When replacing the syphon/bypass hose assembly, inspect these related components to avoid repeat failures.

Inlet strainer / filter

Clogged strainer can mimic a failed syphon hose. Clean or replace as needed.

Bypass valve / pressure relief

A stuck or worn bypass valve can cause poor recirculation and pressure issues.

Pump packing / piston seal

If the pump won't build pressure even after new hoses, check the packings.

Frequently Asked Questions

The assembly includes: one syphon hose, one bypass hose, two pre‑cut hose clamps, and one fitting adapter. All components are pre‑matched for direct replacement on Titan PowrLiner 1800M and 2800M.

Common signs include: difficulty priming, air sputtering from the spray tip, visible cracks or paint weeping from hoses, reduced bypass flow, or the pump running but not pulling material from the container.

While individual hoses may be available separately, Titan recommends replacing both as a matched assembly (704-079A) because both hoses age similarly. Replacing only one often leads to a second failure soon after, increasing downtime.

This assembly is specifically designed for PowrLiner 1800M and 2800M models. Non‑M (earlier) versions may use different hose lengths or fittings. Always consult your machine's parts diagram or contact Titan support to confirm fitment before ordering.
