EGT Weldment Cap 1/4

The EGT Weldment Cap 1/4 from RACEPAK is a precision fitting engineered for exhaust gas temperature measurement systems in high-performance engines. This component serves as a critical interface point in data acquisition setups, allowing engine builders and tuners to monitor real-time EGT readings across multiple cylinder banks. Whether you're developing a race engine, optimizing fuel mixture on a dyno, or troubleshooting combustion efficiency, this weldment cap provides the secure, leak-free connection necessary for accurate telemetry in demanding automotive applications.

Designed with 1/4-inch port compatibility, the EGT Weldment Cap integrates seamlessly into RACEPAK's modular data logging ecosystem and OEM-equivalent exhaust probe systems. The precision-welded construction ensures repeatable sealing without thermal cycling degradation—critical when engine temperatures swing from ambient to over 1,400°F at the exhaust manifold. Compact dimensions (0.95 x 0.95 x 2.05 inches) and minimal weight (0.03 lbs) reduce installation complexity and mass penalty, while the standardized 1/4-inch fitting allows drop-in compatibility with common thermocouple harnesses and signal conditioners used in motorsports and performance tuning.

Professional engine tuners, fabricators, and enthusiasts running RACEPAK or equivalent EGT monitoring systems benefit most from stocking spare weldment caps, as thermal stress or vibration can compromise fitting integrity over time. Installation requires basic familiarity with threaded fittings and exhaust system work; secure the cap hand-tight plus 1/8 turn to avoid over-torquing the delicate thermocouple probe. This product is ideal for complete EGT system builds, sensor replacements, or upgrading legacy carbureted and fuel-injected engine platforms with modern combustion diagnostics.
