197123 - Miller 197123 Buna-N O-Ring .312 ID x .062 CS (5-Pack)

Genuine Miller Replacement O-Rings for Industrial Maintenance

The Miller 197123 O-Ring is a critical replacement component designed to maintain the integrity of your Miller welding equipment. Sold in a convenient package of five, these O-rings are manufactured to strict OEM specifications, ensuring a perfect fit and reliable performance. The O-ring features an Inner Diameter (ID) of 0.312 inches and a cross-section thickness of 0.062 inches, dimensions that are common in various fluid and gas connections within industrial machinery.

Constructed from 70 Durometer Buna-N (Nitrile) rubber, this seal is engineered for resilience and longevity. Buna-N is the standard material for general-purpose sealing applications due to its excellent resistance to petroleum-based oils, fuels, water, and many hydraulic fluids. The 70-durometer hardness provides a balanced combination of flexibility for easy installation and stiffness to resist extrusion under pressure. This makes the Miller 197123 an ideal choice for sealing connections that may be exposed to workshop contaminants or standard operating fluids found in welding environments.

Regular maintenance of your welding equipment often involves inspecting and replacing seals that have degraded over time due to compression set or environmental exposure. A compromised O-ring can lead to gas leaks, which in shielding gas lines can result in weld porosity and poor arc stability. By keeping a pack of Miller 197123 O-rings on hand, maintenance teams can quickly address leaks and ensure that equipment downtime is minimized. Whether you are repairing a specific Miller power source, wire feeder, or accessory, using genuine Miller parts guarantees that the components will function as intended by the manufacturer.

These O-rings are versatile and may fit multiple locations within a Miller system depending on the specific machine model. Always verify the part number against your equipment's parts manual to ensure compatibility. With Josef Gas, you can trust that you are receiving authentic Miller components that meet the high standards required for professional industrial applications.
