⚙️ Key Features

• 90-degree compressed-air fitting
• Starting-air pressure-rated construction
• Correct thread and bore for the original valve/hose
• Maintains hose clearance around the starter
• Uses the specified gasket or thread-sealing method
• Engine type: D5A industrial diesel pneumatic starting system

🔌 Function

Provides a sealed right-angle connection between the pneumatic starter, control valve and air hose.

⚠️ Common Signs of Failure

• Air hissing from the joint when the starting system is pressurised
• Slow or weak cranking as starting air is lost at the fitting
• Thread or sealing face damaged, so the joint will not seal
• Hose being side-loaded or kinked where the elbow has moved
• Cracked body or corroded internal passage found on removal

🛠️ Service Notes

• Use the specified gasket or thread sealing method rather than tape, which can shed into the air circuit
• Nipple 21165583 is the straight equivalent in the same circuit, so select by the routing the installation needs
