The female end carries an internal thread and a precision cone seat machined with a 90 degree included angle (45 degrees per side) in one solid body. It seals metal-to-metal against a male 90 degree cone, with no O-ring, sealant or thread-seal tape, which keeps OEM lines simple and leak-free.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>For OEM designers: this SAE female 90 degree cone seat hydraulic hose fitting matches SAE J513 male 45 degree flare ends and ports, and keeps the hose size independent of the port thread size.<\/li>\r\n<li>For distributors and wholesalers: the matrix covers thread dash -04 to -12 and hose dash -03 to -12, including mixed dash pairs that adapt a large port to a smaller hose.<\/li>\r\n<li>For maintenance teams: the one-piece machined seat is durable, needs no consumables, and inspection of the seat angle is quick and visual.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Core Advantages<\/h3>\r\n\r\n\r\n\r\n<ol class=\"wp-block-list\">\r\n<li>This SAE female 90 degree cone seat hydraulic hose fitting forms a metal-to-metal seal with any matching SAE J513 male 90 degree cone, so no O-ring, sealant or thread-seal tape is needed.<\/li>\r\n<li>Ten standard sizes cover thread dash -04 to -12 and hose dash -03 to -12, with mixed pairs such as 27811-06-04 for port-to-hose flexibility.<\/li>\r\n<li>One-piece machined body: the internal thread and the 45 degree cone seat share the same solid blank, giving a rigid, repeatable seal geometry.<\/li>\r\n<li>HENGHUA process package: cold-headed carbon steel or stainless options, consistent heat treatment, 100% pressure testing and thread gauging.<\/li>\r\n<\/ol>\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 SAE Female 90 Degree Cone Seat Fitting?<\/h3>\r\n\r\n\r\n\r\n<p>The SAE female 90 degree cone seat hydraulic hose fitting is the female half of the SAE 45 degree flare (SAE J513) connection system. Inside the threaded end, a cone-shaped seat is machined at 90 degrees included angle, so the industry calls it a female 90 degree cone seat, a 45 degree flare female end, or a cone seat swivel-style port. The fitting screws over a male 90 degree cone and clamps it against the seat; the two machined surfaces then carry the seal.<\/p>\r\n\r\n\r\n\r\n<p>This system is not interchangeable with JIC 37 degree (SAE J514) or DIN cone ends even when the thread appears to match. Always confirm the seat angle before assembly, because a 45 degree seat cannot seal a 37 degree cone.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Dimensional Data<\/h3>\r\n\r\n\r\n\r\n<table>\r\n<thead>\r\n<tr>\r\n<th style=\"text-align: left;\">Symbol<\/th>\r\n<th style=\"text-align: left;\">Description<\/th>\r\n<\/tr>\r\n<\/thead>\r\n<tbody>\r\n<tr>\r\n<td style=\"text-align: left;\">A<\/td>\r\n<td style=\"text-align: left;\">Overall length from the female end face to the start of the barbs, mm<\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"text-align: left;\">C<\/td>\r\n<td style=\"text-align: left;\">Depth of the internal threaded section, mm<\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"text-align: left;\">E<\/td>\r\n<td style=\"text-align: left;\">Internal thread size of the female end (UNF straight thread)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"text-align: left;\">S2<\/td>\r\n<td style=\"text-align: left;\">Hex across flats on the body, wrench size, mm<\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"text-align: left;\">90\u00b0<\/td>\r\n<td style=\"text-align: left;\">Included angle of the internal cone seat (45 degrees per side)<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n\r\n\r\n\r\n<p>Dimensions A, C and S2 are in millimeters as dimensioned on the drawing.<\/p>\r\n\r\n\r\n\r\n<h3 class=\"wp-block-heading\">Full Dimension Table (Part Number Matrix)<\/h3>\r\n\r\n\r\n\r\n<p>The table below is transcribed from the HENGHUA Series 27811 specification drawing.

The seat clamps over a male 90 degree cone and seals metal-to-metal without any O-ring or sealant.<\/p>\r\n\r\n\r\n\r\n<p><strong>Which male ends does this female fitting connect to?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>It connects to any SAE J513 male 90 degree cone end of the same thread size, such as a SAE 45 degree flare male adapter or a male cone hose fitting like HENGHUA Series 17811. This makes it the natural female counterpart for routing a hose line onto existing male 45 degree flare ports.<\/p>\r\n\r\n\r\n\r\n<p><strong>How do I tell SAE 45 degree flare (J513) from JIC 37 degree (SAE J514)?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Measure the angle of the cone or seat: the SAE J513 seat takes a 90 degree included cone (45 degrees per side) while the JIC seat takes a 37 degree cone. Both use straight UNF threads, so thread size alone cannot tell them apart; always confirm the cone angle before assembly.<\/p>\r\n\r\n\r\n\r\n<p><strong>Can a 45 degree cone seat fitting be used with a JIC 37 degree male end?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>No. The seat angle and the cone angle are different, so the surfaces cannot contact and the joint will leak or damage the parts. Keep SAE J513 components and SAE J514 (JIC) components strictly separate.<\/p>\r\n\r\n\r\n\r\n<p><strong>Does this fitting need an O-ring or sealant?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>No. The SAE J513 45 degree flare system is a metal-to-metal cone seal, and no O-ring, liquid sealant or thread-seal tape is allowed on the seat. A clean, dry seat and cone are what guarantee a leak-free joint.<\/p>\r\n\r\n\r\n\r\n<p><strong>Which hoses does Series 27811 fit?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Series 27811 fits braided hose in dash sizes -03 to -12. If the assembly uses spiral hose, order the same fitting as 27812-XX-XX as noted on the dimension drawing.<\/p>\r\n\r\n\r\n\r\n<p><strong>What is the pressure rating of this fitting?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>This SAE female 90 degree cone seat hydraulic hose fitting is rated by the combination of the hose construction and the connection standard rather than by a single part number. HENGHUA performs a 100% factory pressure test on every fitting and provides the torque and crimp data sheet with each order.<\/p>\r\n\r\n\r\n\r\n<p><strong>Can HENGHUA make a private-label version of Series 27811?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Yes.

Its internal thread and 90 degree cone seat (45 degrees per side) are machined into one solid body, sealing metal-to-metal against a male 90 degree cone, so no O-ring, sealant or thread-seal tape is ever needed. Ten standard sizes cover thread dash -04 to -12 and hose dash -03 to -12, including mixed pairs such as 27811-06-04, and the series suits braided hose; 27812 covers the same profile for spiral hose. Cold-headed carbon steel or stainless options, HRC 20-28, 100% pressure tested with full traceability, OEM marking available.
