1407-0255 - Victor Buna-N O-Ring Size -005

Keep Your Victor Gear Leak-Free

There is nothing more frustrating than setting up for a cut or a weld only to hear the tell-tale hiss of a gas leak. The Victor 1407-0255 O-Ring is your go-to replacement part for fixing those annoying and potentially dangerous leaks in your Victor torches and regulators. Don't rely on generic hardware store O-rings that might not handle the specific pressures or chemical environments of welding gases; stick with genuine Victor parts to ensure your equipment runs exactly as it was designed to.

This O-ring is made from durable Buna-N rubber, which is tough enough to handle the daily grind of a welding shop. It resists tearing and abrasion, meaning you won't have to replace it constantly. With a 70 durometer hardness, it's firm enough to hold a seal under pressure but flexible enough to install easily without snapping. It fits the standard -005 size specification, measuring roughly 1/10th of an inch on the inside diameter, making it a common seal for various small ports and valves in your gas apparatus.

Maintenance is a key part of being a professional welder. Worn-out O-rings are the number one cause of gas waste and equipment malfunction. A dried-out or cracked O-ring can let oxygen or fuel gas escape, creating a safety hazard and costing you money in wasted consumables. We recommend keeping a few of these 1407-0255 O-rings in your toolbox or parts bin. They are small, affordable, and absolutely essential when you are in a pinch during a repair.

Whether you are rebuilding an old regulator or swapping out seals on a cutting attachment, this O-ring provides the factory-fresh fit you need. Installation is straightforward: simply remove the old, worn seal using a non-marring pick, clean the groove, and seat the new Victor O-ring. A little bit of compatible lubricant can help it seat perfectly. Get your gear back to 100% performance and weld with confidence knowing your seals are secure.
