Dual hole ceramic rings feature an optimized double airflow structure that delivers more uniform protective gas output around the nozzle. This improves cutting stability, reduces slag adhesion, and delivers better cutting quality especially for high-speed cutting and thick plate cutting applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Which OSPRI cutting heads use these ceramic rings?\u003c\/strong\u003e\u003cbr\u003e\nA: M8-D17.8 for LC100\/LC200; M8-D21.4-H13 for LC300; 3D-M8-D21.4 for 3D-A\/3D-B; 3D-M8-D21.5 for 3D-C\/3D-D; M10-D25-H19 for LC600; M11-D41-H22 for LC1200; M11-D41-H26.5 for LC2000\/LC3000. If unsure, contact us with your cutting head model.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between 3D-M8-D21.4 and 3D-M8-D21.5?\u003c\/strong\u003e\u003cbr\u003e\nA: The main difference is the outer diameter. 3D-M8-D21.4 is designed for older OSPRI 3D-A and 3D-B robotic cutting heads, while 3D-M8-D21.5 is for newer 3D-C and 3D-D cutting heads. They are not interchangeable due to different dimensions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use universal ceramic rings on my OSPRI laser machine?\u003c\/strong\u003e\u003cbr\u003e\nA: No, OSPRI cutting heads use unique interface specifications and dimensions that differ from standard universal ceramic rings. Using universal ceramic rings on OSPRI equipment will result in poor fit, air leakage, unstable height follow performance and potential damage to your cutting head.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace my OSPRI ceramic ring?\u003c\/strong\u003e\u003cbr\u003e\nA: Under normal operating conditions, an OSPRI ceramic ring should last 2-3 months. However, it should be replaced immediately if you notice any cracks, chips, or if the height follow system becomes unstable. Frequent collisions between the nozzle and workpiece will significantly shorten its service life.\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 30px; padding: 15px; background-color: #e3f2fd; border-radius: 4px;\"\u003e\n  View our full range of \u003ca href=\"https:\/\/www.linkmetalcnc.com\/collections\/laser-cutting-accessories\" style=\"color: #1976d2 !important; text-decoration: none; font-weight: 500 !important;\"\u003elaser cutting accessories\u003c\/a\u003e including OSPRI nozzles and protective lenses.\n\u003c\/p\u003e","brand":"Link Metal CNC","offers":[{"title":"M8-D17.8 Single Hole","offer_id":47965381722334,"sku":"LMCNC-CERAMIC-OSPRI-M8D17.8-SINGLEHOLE","price":3.39,"currency_code":"USD","in_stock":true},{"title":"M8-D17.8 Dual Hole（FC-11）","offer_id":47965381689566,"sku":"LMCNC-CERAMIC-OSPRI-M8D17.8-DUALHOLE","price":3.9,"currency_code":"USD","in_stock":true},{"title":"3D-M8-D21.4 (Dual Hole)（FC-40）","offer_id":47965381656798,"sku":"LMCNC-CERAMIC-OSPRI-3DM8-D21.4","price":4.25,"currency_code":"USD","in_stock":true},{"title":"M8-D21.4-H13(Three Holes)（FC-15）","offer_id":47965381886174,"sku":"LMCNC-CERAMIC-OSPRI-M8D21.4-H13","price":5.2,"currency_code":"USD","in_stock":true},{"title":"3D-M8-D21.5（FC-218）","offer_id":47965381755102,"sku":"LMCNC-CERAMIC-OSPRI-3DM8-D21.5","price":4.25,"currency_code":"USD","in_stock":true},{"title":"M10-D25-H19（FC-04）","offer_id":47965381787870,"sku":"LMCNC-CERAMIC-OSPRI-M10D25-H19","price":7.09,"currency_code":"USD","in_stock":true},{"title":"M11-D41-H22（FC-14）","offer_id":47965381820638,"sku":"LMCNC-CERAMIC-OSPRI-M11D41-H22","price":28.36,"currency_code":"USD","in_stock":true},{"title":"M11-D41-H26.5( FC17）","offer_id":47965381853406,"sku":"LMCNC-CERAMIC-OSPRI-M11D41-H26.5","price":43.71,"currency_code":"USD","in_stock":true},{"title":"Other models available upon request.","offer_id":48010260873438,"sku":null,"price":3.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0778\/8858\/5950\/files\/link-metal-cnc-ospri-ceramic-ring-01.jpg?v=1773117886","url":"https:\/\/www.linkmetalcnc.com\/ru\/products\/ospri-ceramic-ring-fiber-laser-cutting-head","provider":"Link Metal CNC ","version":"1.0","type":"link"}
