71Z33 - ESAB Replacement Regulator Filter Inlet Nipple

Protect Your Regulator with the ESAB Filter Inlet Nipple

Your gas regulator is the heart of your welding or cutting setup, controlling the immense pressure of a gas cylinder down to a usable working pressure. The ESAB 71Z33 Filter Inlet Nipple is the first line of defense for this expensive piece of equipment. Located at the inlet where the regulator connects to the gas source, this nipple does more than just connect pipes—it contains a built-in filter designed to catch dirt, dust, and metal shavings that might be hiding inside your gas cylinder valve.

Why is this small part so important? Inside your regulator, a high-pressure seat opens and closes to control gas flow. If even a tiny piece of grit gets past the inlet, it can embed itself in that seat. This prevents the regulator from sealing properly, leading to a dangerous condition called "creep," where the delivery pressure keeps climbing even when you aren't welding. In severe cases, this can blow out the diaphragm or damage your hoses. By replacing your inlet nipple with the ESAB 71Z33, you ensure that the sintered filter is clean and effective, stopping contaminants dead in their tracks before they can cause expensive damage.

This replacement nipple is machined from high-quality brass, ensuring it stands up to the wear and tear of daily cylinder changes. It is designed as a direct fit for compatible ESAB and Victor style regulators, making maintenance straightforward. If you notice reduced gas flow or if your old inlet filter looks dark and clogged, it is time to swap it out. Don't risk your weld quality or your safety with a compromised regulator. Keeping a spare 71Z33 in your toolbox ensures you can perform quick field repairs and keep your arc burning or your torch cutting without downtime. Trust in genuine ESAB parts to keep your equipment running as smoothly as the day you bought it.
