Overview

The Miller MW15 O-Ring Seal Rings are replacement sealing components designed specifically for Smith Equipment's medium-duty welding and cutting product lines. Each pack includes 25 rubber O-rings, making it a practical bulk purchase for workshops, fabrication shops, or anyone who relies on Smith MW series welding tips, MT series heating tips, or compatible cutting attachments like the DG109A, MC509, MC505, and CC509P. Keeping spare O-rings on hand ensures that a worn or damaged seal doesn't bring work to a halt.

As a genuine Miller consumable, these O-rings are manufactured to match the tolerances and material specifications required for proper sealing under the heat and pressure of welding and cutting operations. Rubber construction provides the flexibility needed to form a tight, leak-proof seal while withstanding the demands of medium-duty use. For anyone maintaining Smith equipment, this 25-pack is an economical way to stay stocked on an essential wear item.
