There is nothing more frustrating than a regulator that won't hold steady pressure. You set it to 20 PSI, pull the trigger, and watch the needle drop, or worse—you stop welding and watch the needle slowly climb into the red zone. This phenomenon, known as "creep," is often caused by a worn-out or stiff diaphragm that can no longer seal properly. The ESAB 999861 Low Temperature Diaphragm is the solution for welders working in the cold or with gases like CO2 that tend to freeze up standard equipment. Don't replace the whole regulator when a simple part swap can make it run like new.
Cold weather is the enemy of rubber. If you are welding outside in the winter or running high-flow shielding gas, your regulator's internal rubber parts can turn into hard plastic. When that happens, the diaphragm can't flex to open and close the valve seat effectively, leading to erratic arcs and wasted gas. This "Low Temp" diaphragm is built specifically to stay soft and pliable when the temperature drops. This means you get instant gas flow when you strike an arc and a tight, leak-free seal when you stop, regardless of the weather.
Safety is paramount when dealing with high-pressure cylinders. A compromised diaphragm isn't just an annoyance; it's a hazard that can lead to dangerous pressure buildup in your hoses. Swapping out your old, cracked diaphragm with this genuine ESAB replacement is a quick and cost-effective maintenance task that protects your equipment and your shop. Keep a spare in your toolbox so you never get shut down by a blown regulator in the middle of a job. Trust genuine ESAB parts to keep your flame steady and your welds clean.
