Chemical suction set M22-M22

The M22-M22 chemical suction set with filter is a complete detergent accessory set with M22 connections on both ends. The suction-side filter is designed to stop debris from the chemical container so it doesn’t enter the chemical circuit components and cause sticking, interruptions, or leaks.

MPN / reference: 133761
Connection standard: M22 - M22

APPLICATION

The set is used wherever detergent needs to be drawn from an external container:

• feeding detergent for cleaning jobs that require pre-spray or foaming (depending on system configuration),
• servicing/restoring a complete chemical suction line after hose/end damage,
• equipping a station with a filtered set where the chemical circuit is sensitive to contamination,
• workshop work where detergents are changed often and a quick, repeatable M22 connection is needed.

SYMPTOMS - WHEN IT’S WORTH REPLACING (SET/COMPONENTS)

Consider replacing the set (or using a new complete set) when you notice:

• no chemical suction despite correct detergent setting,
• intermittent suction (works sometimes, sometimes not), especially during longer runs,
• leakage at M22 connections (“sweating”/drips),
• suction filter is damaged or permanently clogged with deposits,
• clearly worn threads or difficulty assembling connections straight.

HOW TO CHOOSE THE RIGHT PART

To ensure the set works correctly:

• confirm M22-M22 connections are required on the accessory side,
• verify the part number: MPN 133761,
• compare with your existing setup (external suction + suction filter used in your configuration),
• check mating components (M22 sockets, seals) are in good condition-worn seats can leak regardless of a new set.

In a chemical suction circuit, airtightness is critical-even a small air leak can “kill” suction.

COMPATIBILITY

Select the set based on the M22-M22 standard and compatibility with the chemical suction system in your washer/accessory configuration. Because M22 exists in multiple variants, safest confirmation is by MPN 133761 and comparison with the part being replaced.

Why is the filter important if it’s “just detergent”?|Because chemical containers often contain small debris, deposits, or bits of labels/caps. Without a filter, contaminants can block chemical-circuit components and cause intermittent suction.

Chemical suction works sometimes and not others-what should I check first?|First check filter and suction line flow, then connection tightness (suction is very sensitive to air leaks). Only after that does it make sense to suspect the chemical valve or control components.

Will this M22-M22 set fit if I have M22 but a different end variant?|Not always. “M22” alone can be insufficient because clamping geometry and sealing can differ. Best verification is MPN 133761 and comparison with the removed part.

Can I use the set without the filter if my detergent is clean?|It may be possible, but the risk of sticking and suction issues increases. The filter is simple protection and usually stabilizes operation under varying conditions.

How can I tell the issue is in the suction set and not in the washer itself?|If cleaning the filter and sealing connections restores suction or stops leaks, the suction line/accessories are usually the cause. If symptoms persist, then it’s reasonable to diagnose the chemical valve and control elements in the machine.
