82Z47 - Victor Regulator Burst Discs - 5 Pack

Keep Your Regulator Running Safely

Every welder knows the sound—a loud pop followed by the hiss of escaping gas. It’s the sound of your regulator's safety disc doing its job. The Victor 82Z47 Safety Release Disc is the sacrificial part that blows so your regulator doesn't. When pressure spikes due to a dirty seat, a sudden opening of the cylinder valve, or a malfunction, this little disc ruptures to let the gas out safely, protecting the internal diaphragm and gauges of your expensive equipment. If you are running Victor regulators in your shop or on your rig, keeping a pack of these 82Z47 discs in your toolbox is a no-brainer.

Quick Fix for a Common Problem

A blown safety disc stops work immediately. You can't tape it up, and you definitely shouldn't try to plug it. The only fix is a replacement. Having this 5-pack on hand means you can be back up and running in minutes rather than waiting days for a part to ship. It is one of the cheapest insurance policies you can buy for your oxy-fuel or shielding gas setup. These discs are designed to fit perfectly into the safety cap of compatible Victor regulators, ensuring a tight seal until—and unless—they are needed to vent pressure.

Why OEM Matters

You might be tempted to find a washer or a piece of metal to shim it, but that is a recipe for disaster. These discs are calibrated to burst at a very specific pressure. If you use something too strong, the next time there is a pressure spike, the regulator housing could explode instead of the disc venting. Stick with the genuine Victor 82Z47 to ensure that the burst pressure matches your regulator's specs. It’s about protecting yourself and the guys working around you. The metal is specifically chosen to handle the rigors of high-pressure gas without corroding or weakening over time, so it's ready when it counts.

Shop Essentials

This pack contains five discs, which is perfect for a busy shop. If one regulator blows a disc, it’s often a sign that you might have some debris in the system or a creeping regulator, so it’s good to have spares while you troubleshoot the root cause. Don't let a ten-dollar part cost you a thousand-dollar job. Swap out the blown disc, check your cylinder valve opening procedure (crack it slow!), and get back to laying beads. Whether you are cutting steel with oxy-acetylene or welding with an argon mix, your regulator is the heart of your gas delivery, and this disc is its safety vest.
