⚠️ Common Signs of Failure

• Air hissing at the hose stem under pressure
• Hose creeping off or blowing off the nipple
• Weak or slow cranking through lost starting air
• Hose stem corroded, scored or the sealing shoulder damaged
• Bore found restricted by corrosion or scale on strip-down

🛠️ Service Notes

• Check the strainer, ball valve and hose condition at the same time, as they share the same circuit and contamination
• Straight nipple 21165583 is the alternative where the routing does not need a 90 degree turn
