🔌 Function

Provides the shoulder and axial spacing that correctly locates the plate-stack end support beneath the top plate.

⚠️ Common Signs of Failure

• Collar corrosion or deformation
• Incorrect plate-stack height
• Loose or uneven top plate
• Leakage from poor gasket compression
• Wear around the spacer-tube interface

🛠️ Service Notes

• Two collars are fitted per heat exchanger, working with liner 21111123 and spacer tube 21111110 to set the plate-stack end stand-off - order the matching liner and spacer together if rebuilding the whole end assembly
• At only 0.018 kg this is a small precision spacer rather than a structural part - keep it separated from the liner during strip-down so it isn't lost or swapped
