OVERVIEW

Fix Your Regulator and Get Back to Welding

A leaking or creeping regulator can ruin your welds and waste expensive shielding gas. Often, the culprit is a worn-out diaphragm. This 5-pack of replacement diaphragms is the perfect solution for welders looking to rebuild their gear and get back to work. With a specific size of 1.66" OD x .070" thickness, these diaphragms are designed to fit compatible gas regulators, restoring the sensitivity and pressure control you need for a stable arc.

Why buy a whole new regulator when you can fix the one you have? These diaphragms are built tough to handle the rigors of the shop environment. The pack of five means you'll have extras for your toolbox or for fixing multiple regulators in your shop. A good diaphragm ensures that when you set your flow rate, it stays there, preventing gas surges that can cause porosity or lack of coverage. It's a small part that makes a huge difference in your weld quality.

Don't let a bad regulator slow you down. Swapping out a diaphragm is a straightforward repair that can save you money and keep your equipment running safely. These replacements offer the flexibility and durability required for consistent gas delivery, whether you are running Argon, CO2, or Oxygen. Check your regulator's manual or measure your old diaphragm to ensure these 1.66-inch replacements are the right fit, and keep your gas system leak-free and reliable.

FAQ

The diaphragm has an outer diameter (OD) of 1.66 inches and a thickness of 0.070 inches.

This product is sold as a bag containing 5 diaphragms.

It serves as the sensing element in a gas regulator, controlling the valve opening to maintain consistent outlet pressure.

No, it is sized specifically (1.66" OD). You must verify the dimensions of your existing diaphragm or check your regulator's parts list for compatibility.

While diaphragms are generally compatible with common welding gases, always ensure the material and part number match the manufacturer's specifications for oxygen service to ensure safety.

Diaphragms can dry rot, crack, or lose elasticity over time, causing gas leaks or unstable pressure delivery (creep).

This specific SKU is packaged and sold as a bag of 5 units.
