Every 1Q metric male 74\u00b0 cone adapter is therefore machined with the cone turned on a CNC lathe in the same setup as its thread, measured for included angle and seat diameter on a profile projector, and gauged for thread fit 6g go \/ no-go. The inspection record travels with the lot, and the cone can be re-verified years later against the same drawing.<\/p>\r\n\r\n\r\n\r\n<p>The part is a straight (180\u00b0) adapter with a metric male 74\u00b0 cone end on both sides, of equal size on each end in the standard range. It is used to join two 74\u00b0 cone connections \u2014 typically two tube ends carried by sleeves and nuts \u2014 or to place a 74\u00b0 cone connection onto a 74\u00b0 cone port. The catalogue also lists the 1Q-RN version of the same body, supplied complete with cutting ring and nut.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Core Advantages<\/h3>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Wide-angle metal seat.<\/strong> The 74\u00b0 cone seals on a broad metal-to-metal band rather than a thin lip, so it tolerates the slight misalignment that a tube run assembled in the field always has. No elastomer sits in the sealing path.<\/li>\r\n<li><strong>Double-ended simplicity.<\/strong> One adapter, two identical 74\u00b0 cone ends, one part number per size \u2014 no orientation, no handedness, no assembly sequence to get wrong.<\/li>\r\n<li><strong>Threads matched to the cone.<\/strong> The cone and its thread are cut in one setup, so seat concentricity is a machining result rather than an assembly assumption.<\/li>\r\n<li><strong>Full size range.<\/strong> Tube 5 mm through 34 mm, with M10\u00d71 up to M45\u00d72.<\/li>\r\n<li><strong>Complete-set option.<\/strong> The \/RN variant adds the cutting ring (sleeve NB500-Q) and nut (NB200-Q) so the connection can be ordered as one kit.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Technical Specifications<\/h2>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">What Is a Metric Male 74\u00b0 Cone Adapter?<\/h3>\r\n\r\n\r\n\r\n<p>It is a straight hydraulic adapter whose two connections are metric male studs with an external 74\u00b0 cone. The cone seats against a matching internal 74\u00b0 cone in the mating component; the mechanical load and the seal are both carried by the cone faces. On the tube side, the mating end is normally a tube carried by a sleeve (cutting ring or bite-type ferrule) and a nut, which presses the tube&#8217;s cone into the adapter&#8217;s cone.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Cone Geometry \u2014 74\u00b0, 60\u00b0 and 37\u00b0 Are Not Interchangeable<\/h3>\r\n\r\n\r\n\r\n<p>This is the single most important thing to check before buying a cone adapter.
