Adding ancillary ports to your intercooler or engine cooling system can be a challenge, especially if you don't have access to metal fabrication equipment. Our team recognized the need for an easy-to-install 1/8"-NPT adapter bung for use on existing rubber or silicone couplers. Keeping this install tidy and professional was our primary goal, which we achieved by designing a subtle fitting from high-quality materials. Our 1/8-in-NPT hose bung is precisely CNC-machined from 6061 aluminum. We’ve also machined space for a durable silicone O-ring to ensure a leak-free seal with both air and liquid passageways. Our 1/8-in-NPT adapter bung features a durable black anodized finish, ensuring optimal resistance against corrosion. This adapter can be installed in minutes and accepts any 1/8" NPT accessory such as injection nozzles, sending units, and sensors. As with all our products, this aluminum 1/8-in-NPT add-in bung includes our signature Mishimoto Lifetime Warranty.
