Function of the Swivel

The Mosmatic 43.354 WDC Swivel helps:

Common Signs Replacement Is Needed

Replace the swivel if you notice:

• Water leaking around the swivel body
• Restricted or rough swivel rotation
• Excessive hose twisting
• Damaged or worn threads
• Corrosion or physical damage
• Reduced swivel performance under pressure

Replacing a worn swivel restores reliable hose movement and helps prevent premature hose and fitting wear.

Installation & Service Notes

Turn off the pressure washer and relieve all system pressure before installation.

Apply an appropriate thread sealant where required and install the swivel using the 1/2" Female NPT inlet and 1/2" Female NPT outlet connections.

Tighten all fittings securely without overtightening.

Verify the swivel rotates freely and inspect the system for leaks before placing equipment into service.

Important: Never exceed the maximum 4,000 PSI working pressure. Always verify compatibility with your pressure washer system, plumbing components, and operating conditions before installation.

Maintenance Recommendations

• Inspect the swivel regularly for leaks and smooth rotation.
• Check threaded connections during routine maintenance.
• Keep the swivel clean and free of dirt, debris, and mineral buildup.
• Replace worn seals or damaged components promptly.
• Inspect hoses for twisting or abnormal wear during operation.
• Use only genuine OEM Mosmatic replacement parts to maintain proper fit, reliable performance, and long-term service life.
