⚠️ Common Signs of Failure

• Pressure or flow outside specification
• Leakage through the valve body or connections
• Valve sticking open or closed
• Repeated alarms or unstable system operation
• Corrosion, contamination or damaged sealing surfaces

🛠️ Service Notes

• Because this is a swivel fitting, it should seal on a face, washer or O-ring at the swivel joint rather than on the thread — don't rely on thread sealant to stop a leak here, since that only stops it turning
• Orient the hose or pipe connection first, then nip the swivel up only enough to hold that orientation under vibration; overtightening a swivel joint defeats the reason for fitting one
