{"product_id":"ptfe-20-graphite-tube-rod","title":"PTFE + 20% Graphite — Tube \u0026 Rod","description":"\u003cp\u003ePTFE filled with 20% graphite. Graphite enhances self-lubrication and reduces friction below that of virgin PTFE — ideal for dry-running seals, bearings, and sliding applications where external lubrication is limited. Good thermal conductivity and broad chemical resistance.
