It physically blocks the collet from releasing, so the PTFE tube cannot back out even under high retraction forces. Without it, aggressive retraction settings can gradually pull the tube loose, causing a gap between the tube end and nozzle — which leads to clogs and under-extrusion.\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cdiv class=\"faq-q\"\u003eIs this the same as the coupler itself?\u003c\/div\u003e\n    \u003cdiv class=\"faq-a\"\u003eNo — this is the retainer clip only, not the pneumatic coupler. It locks into an existing PC4-M6 or PC4-01 fitting.
