Description
The Mishimoto MMFT-NZL-18BK is a precision CNC-machined 1/8-in NPT hose bung engineered to add ancillary ports to your intercooler piping or engine cooling system without requiring metal fabrication equipment. Machined from 6061 aluminum and finished in a durable black anodized coating, this Mishimoto Fabrication adapter bung installs directly into existing rubber or silicone couplers in minutes, giving you a clean, factory-look mounting point for accessories.
Whether you’re tapping into a radiator hose, intercooler coupler, or another section of your engine cooling system, this aluminum bung gives fabricators and DIY builders an easy way to accept any 1/8-in NPT accessory, including injection nozzles, sending units, and sensors. A machined recess houses a durable silicone O-ring that maintains a leak-free seal across both air and liquid passageways, so the bung performs reliably whether it’s plumbed into a fluid line or a pressurized air system. As a Mishimoto Fabrication product, it’s built to keep custom cooling and intercooler setups looking tidy and professional rather than improvised.
Vehicle Applications
This NPT bung is a universal fabrication component rather than a vehicle-specific part, so it isn’t tied to one particular make, model, or year. Instead, it’s designed to work on any rubber or silicone coupler found within an intercooler piping system or engine cooling system, including radiator hoses and similar liquid or air couplers, making it a flexible option for custom builds across a wide range of cars, trucks, and other vehicles that use these hose types.
