Weld-In Temp. Adapter

The Weld-In Temp. Adapter by AutoMeter is a precision-engineered temperature probe bung designed for permanent installation in custom engine builds and high-performance cooling systems. This weld-on adapter provides a secure, vibration-resistant mounting point for temperature sensors in applications where traditional bolt-in bungs are impractical. Whether you're fabricating a race engine, building a custom cooling loop, or upgrading an existing system, this adapter offers the durability and reliability that serious enthusiasts and professional builders demand.

Constructed from durable steel with a natural finish, the Weld-In Temp. Adapter features a 5/8-18 female thread specification that accepts standard AutoMeter temperature probes and compatible sensors. The weld-on design eliminates the need for threaded bungs or adapters, reducing potential leak points and providing a clean, integrated installation directly into your cooling system or manifold. The compact footprint—measuring 2.85 x 0.95 x 3.9 inches—allows flexible placement in tight engine bays, while the steel construction ensures longevity under extreme temperatures and thermal cycling.

This adapter is ideal for custom fabricators, performance shops, and DIY builders who require precise engine temperature monitoring in non-standard applications. Its weld-on construction makes it particularly valuable in applications where existing threaded ports are unavailable or unreliable. Compatible with any AutoMeter or standard 5/8-18 temperature probe, the Weld-In Temp. Adapter integrates seamlessly into cooling systems, exhaust manifolds, and transmission lines, providing accurate real-time data to your digital or analog gauge cluster for critical temperature management.
