1/4" Stainless Steel Weld-on Base Only

Overview

Professional-grade stainless steel weld-on sensor base for mounting temperature probes and other 1/4" threaded sensors in custom fabrications. Essential for accurate exhaust gas temperature monitoring, coolant temperature sensing, and oil temperature measurement in high-performance builds where precision data acquisition drives tuning success.

Technical Specifications

• Part Number: HT-010811
• Thread Size: 1/4" NPT
• Material: Stainless steel construction
• Installation: Weld-on mount
• Application: Temperature sensors and data acquisition probes

Why You Need This

Accurate temperature monitoring is critical in modern engine management, particularly when running aggressive tune files or forced induction setups. This weld-on base provides a robust mounting point for EGT probes in custom exhaust manifolds, downpipes, or turbo housings—essential data points for protecting your investment during high-boost applications or track use. The stainless construction withstands extreme exhaust temperatures whilst maintaining sensor accuracy over thousands of heat cycles.

We see this fitted to everything from LS swap projects requiring custom exhaust work to RB25/RB26 builds where fabricated manifolds need multiple temperature monitoring points. It's also invaluable for oil temperature sensing in dry sump systems or monitoring coolant temps at critical points in race-spec cooling systems. The professional weld-on design ensures sensor positioning exactly where you need it, rather than compromising with threaded bungs in less-than-ideal locations.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range when paired with appropriate temperature sensors. Works seamlessly with Elite 550, 750, 1000, 1500, 2000, and 2500 ECUs, plus Nexus R3 and R5 systems. Contact our technical team to specify the correct sensor pairing for your monitoring requirements and ECU configuration.
