1/4" Mild Steel Weld-on Kit - inc Nut and Ferrule

Overview

The Haltech 1/4" Mild Steel Weld-on Kit provides a robust, permanent mounting solution for pressure and temperature sensors in high-performance engine builds. Engineered for durability in demanding motorsport applications, this kit eliminates the unreliable threaded adapters and push-fit connections that plague professional builds when precise sensor positioning and leak-free operation are critical.

Technical Specifications

• Part Number: HT-010810
• Material: Mild steel construction
• Thread Size: 1/4" NPT
• Installation Method: TIG weld-on
• Application: Pressure and temperature sensors

Why You Need This

Professional engine builds demand permanent, leak-proof sensor mounting that won't fail under heat cycling or vibration. Standard threaded bungs often work loose or leak, particularly on turbo manifolds, oil galleries, and coolant systems where sensor accuracy is crucial for safe tuning. This weld-on kit eliminates those failure points entirely.

We see this specification constantly in serious builds — LS turbo conversions requiring accurate oil pressure monitoring, RB25/26 engines with aftermarket manifolds needing multiple temperature points, and 2JZ setups where boost pressure sensors must be positioned precisely for ECU mapping. The mild steel construction suits most exhaust manifold and intake plenum applications, whilst the included nut and ferrule ensure your expensive Haltech sensors mount securely without thread damage during installation or removal for maintenance.

ECU & System Compatibility

Compatible with all Haltech pressure and temperature sensors across the Elite 550/750/1000/1500/2000/2500 and Nexus R3/R5 ranges. Essential for professional installations where sensor positioning affects ECU calibration accuracy and long-term reliability.
