OVERVIEW

Reliable Gas Sealing for Tweco MIG Systems

The Tweco 224-S O-Ring (Part No. 2064-2059) is a critical replacement component designed specifically for the Tweco #4 Power Pin. In the demanding environment of industrial welding, the integrity of your shielding gas delivery system is paramount. Even the smallest leak at the power pin connection can lead to significant gas wastage, turbulent flow, and ultimately, compromised weld quality due to porosity. This O-ring serves as the primary seal between the MIG gun's power pin and the wire feeder or adapter, ensuring that 100% of your shielding gas reaches the weld pool.

Manufactured from durable, high-grade elastomer, these O-rings are engineered to withstand the mechanical stress of frequent gun connecting and disconnecting, as well as the environmental factors typical of a welding shop. Over time, rubber components can dry out, crack, or become compressed, losing their ability to form a tight seal. Regular inspection and replacement of the power pin O-ring is a standard preventive maintenance procedure that protects your welding investments.

This product is supplied in a convenient bag of 10, providing excellent value for fabrication shops and maintenance departments. Having a stock of these essential seals ensures that production never halts due to a minor consumable failure. Whether you are refurbishing older equipment or maintaining a fleet of Tweco MIG guns, the 224-S O-ring is the exact fit required to restore factory-level performance to your gas connections.

Key Technical Benefits

  • Precision Fit: Molded to exact dimensions for the Tweco #4 Power Pin groove.
  • Material Durability: Resists compression set and common shop chemicals.
  • Cost Efficiency: Bulk packaging reduces per-unit cost and simplifies inventory management.

FAQ

This O-ring (224-S) is designed to fit the groove on a standard Tweco #4 Power Pin, which is the connector found on the back end of many Tweco MIG guns.

This product is sold as a bag of 10 O-rings.

Common signs include audible hissing at the feeder connection, higher than normal gas usage, or porosity in your welds due to insufficient gas coverage.

This item corresponds to Tweco part number 2064-2059 (224-S). It is designed to meet or exceed OEM specifications for fit and seal.

Yes, applying a very small amount of O-ring lubricant or even a touch of nozzle gel can help the O-ring slide into the feeder port without tearing or bunching up.

It is specifically sized for the Tweco #4 style. While some other brands may copy this style (Tweco-style), you should verify the pin type is a #4 before purchasing.

It is made from a durable industrial elastomer (rubber) designed to resist the compression and environmental conditions of welding workshops.

Absolutely. If air is sucked in or gas leaks out at the power pin, your shielding gas coverage at the nozzle will be compromised, leading to porosity.
