Common Signs Replacement Is Needed
Replace the swivel if you notice:
- Water leaking around the swivel body
- Restricted or rough rotation
- Damaged or worn threads

- Corrosion or physical damage
- Excessive rotational play or seal wear
Replacing a worn swivel restores smooth hose movement and helps protect hoses and connected equipment.
Installation & Service Notes
Turn off the system and relieve all pressure before installation.
Apply an appropriate thread sealant where required and install the swivel using the 3/8" Female NPT inlet and 3/8" Male NPT outlet connections.
Tighten all threaded fittings securely without overtightening.
Verify the swivel rotates freely and inspect for leaks before placing the equipment into service.
Important: Never exceed the maximum 725 PSI working pressure, 250°F operating temperature, 30 RPM, or 37 ft-lbs of torque. Always verify compatibility with your hose reel and operating system before installation.
Maintenance Recommendations
- The maintenance-free design requires no routine lubrication.
- Inspect the swivel periodically for leaks and smooth rotation.
- Check threaded connections during routine equipment maintenance.
- Inspect NBR seals for signs of wear if leakage develops.
- Keep the swivel clean and free of dirt or debris.
- Use only genuine OEM Mosmatic replacement parts if service is required to maintain reliable, long-term performance.
