Miller H713-23 Sintered Inlet Filter Cone for Gas Regulators

Don't Let Dirt Ruin Your Regulator

Every time you crack open a new cylinder of oxygen, argon, or acetylene, you are potentially unleashing a stream of invisible debris into your welding gear. The Miller H713-23 Filter, Regulator Inlet Cone is your first line of defense against the rust, dust, and cylinder scale that lives inside even the cleanest-looking tanks. This small, cone-shaped filter sits right inside the inlet nipple of your regulator, acting as a gatekeeper that lets gas flow through while stopping solid particles dead in their tracks.

Why is this little part so important? Inside your regulator is a high-pressure seat assembly that opens and closes thousands of times to control gas pressure. If a piece of grit—even one the size of a grain of sand—gets lodged between the seat and the nozzle, your regulator can't close properly. This leads to "creep," where the gauge pressure keeps climbing even when you aren't welding, which can blow out diaphragms, damage hoses, or cause dangerous leaks. Replacing the H713-23 filter is a cheap and easy way to prevent these expensive failures.

Designed to fit Miller and Smith regulators, this sintered metal filter is built to handle high-pressure environments. Unlike simple wire mesh screens that can tear or let fine dust pass, the sintered cone structure provides a tortuous path for gas, trapping contaminants effectively without starving your torch or welder of the flow it needs. It is durable, heat-resistant, and essential for anyone who wants their equipment to last.

Installation is straightforward and should be done whenever you notice the old filter is dark, clogged, or crushed. Many welders keep a few H713-23 filters in their toolbox as cheap insurance. Don't wait until your regulator starts acting up or leaking; check your inlet filter regularly. Keeping a fresh filter in your inlet nipple ensures smooth gas flow, stable arcs, and peace of mind knowing your gear is protected from the inside out.
