OVERVIEW

Genuine Victor 1407-0187 O-Ring Seal

Keep your Victor welding and cutting equipment operating at peak performance with the genuine 1407-0187 O-Ring. Leaks in gas apparatus are not just an annoyance—they are a safety hazard and a source of wasted gas. This replacement seal is engineered specifically for Victor equipment, ensuring that you get the tight, reliable seal necessary for safe operation. Whether you are rebuilding a regulator or servicing a torch, using the correct O-ring is the first step in a successful repair.

Constructed from durable Buna-N (Nitrile), this O-ring provides a robust seal that resists tearing and abrasion. Buna-N is the industry standard for many sealing applications due to its excellent balance of flexibility and durability. It stands up well to the rigors of the shop environment, including exposure to oils and greases that might degrade lesser materials. The 1407-0187 measures approximately 3 inches in diameter, making it a substantial seal for larger connection points or internal assembly seals.

Don't compromise on safety or performance by using ill-fitting generic seals. The Victor 1407-0187 is manufactured to exact tolerances (2.989" ID x 3.125" OD) to ensure it seats perfectly in the hardware groove. Installation is straightforward: simply ensure the groove is clean and free of debris, and seat the O-ring gently to avoid twisting. Regular maintenance with genuine parts helps extend the life of your valuable tools and ensures consistent flame characteristics and pressure control.

Yes, this is a genuine Victor 1407-0187 replacement part.

It fits specific Victor gas apparatus, typically larger regulators or torch assemblies. Please check your equipment's parts diagram for the specific part number 1407-0187.

Buna-N is commonly used in many gas applications, but for high-pressure oxygen service, manufacturers sometimes specify other materials. Always verify the specific requirements of your device in the service manual.

O-rings should be inspected regularly during maintenance. If they show signs of cracking, flattening, or brittleness, they should be replaced immediately to prevent leaks.

Typically, these O-rings are supplied dry. You may need to apply a compatible lubricant (like an oxygen-safe lubricant if used in gas service) during installation.

The 0.070-inch width ensures the O-ring compresses correctly in the groove. An incorrect width can lead to either a loose seal or an inability to assemble the parts.
