Nissan Fairlady/300ZX Z32 Heater Hose Clamp Towards Grommet (Late)

Terra Firma Automotive supplies genuine Nissan cooling system hardware that ensures your Z32 Fairlady or 300ZX maintains factory-correct hose security and leak-free performance. This late-model 22mm heater hose clamp is the exact OEM replacement engineered specifically for the grommet-side connection where the heater hoses pass through the firewall on these iconic sports cars. Precision-formed to Nissan’s updated specifications, it provides consistent tension across the full 22mm diameter range while resisting corrosion and maintaining clamping force through years of thermal cycling and engine vibration.

Late-production Z32 owners restoring or servicing their cooling systems know that original clamps can lose tension or corrode over time, leading to slow coolant leaks at the firewall, reduced heater performance, or drips into the cabin. Installing this authentic late-version clamp restores a factory-tight, professional connection that prevents seepage and ensures reliable coolant flow to the heater core. Its durable construction and exact sizing deliver superior long-term sealing performance compared to generic alternatives, especially on Fairladys built after January 1997.

At Terra Firma Automotive, we are the trusted premium source for hard-to-find OEM fasteners and cooling components that serious enthusiasts and restorers rely on. Whether you are replacing deteriorated heater hoses, refreshing the entire cooling system on your twin-turbo, addressing leaks during an engine bay restoration, or maintaining a late-production naturally aspirated example, this grommet-side clamp upholds the precise engineering and long-term reliability that define the Fairlady Z and 300ZX.
