Installing a gas regulator correctly is essential to ensuring safe and reliable operation. One of the most common issues reported by customers working with the USG Model 243 regulator is improper installation of the tetraseal. While small, this component plays a critical role in performance—and a misstep during installation can lead to system failure.
To help troubleshoot this issue, we’ve created a short, informative training video. Watch as we walk you through the correct process for installing the tetraseal, and learn some key tips to ensure success during setup.
Watch the Video: How to Properly Install the Tetraseal on a Model 243 Regulator
In this step-by-step walkthrough, we demonstrate the correct placement of the tetraseal within the regulator body and explain why proper positioning is critical to functionality.
Key Takeaways
- The tetraseal must be installed on the internal shelf of the regulator body—not around the outside throat.
- Incorrect placement prevents the seat from disengaging the orifice, leading to system failure.
- The procedure is simple but commonly overlooked during installation.
- The video outlines how to disassemble, install, and reassemble the body correctly.
- Always confirm proper tetraseal placement before tightening bolts and reinstalling in the pipeline.
Why Proper Tetraseal Installation Matters
While the tetraseal might seem like a minor component, it directly affects whether your regulator functions as designed. Without a secure seal in the correct position, the pressure seat cannot operate properly—effectively rendering the unit non-functional.
