The flange geometry follows SAE J518 \/ ISO 6162-1 (Code 61), and the hose-end and interlock profile are built to ISO 12151-3 and SAE J516, as printed on the data sheet. The interlock collar positively locks the spiral reinforcement in place during crimping, so the joint survives impulse-heavy circuits without a welded seam.<\/p>\r\n\r\n\r\n\r\n<p>For an OEM, this interlock design gives a repeatable flange interface for four- and six-spiral hose programs and a clean interchange with legacy Code 61 layouts. For a distributor, one catalog line covers five flange sizes of SAE 3000 psi flange fittings across the common spiral-hose bores. For a maintenance team, it is a direct replacement that restores the line without re-engineering the routing.<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Straight configuration with interlock collar designed for spiral-wound hose.<\/li>\r\n<li>3\/4&#8243; to 2&#8243; Code 61 flange sizes, covering DN 20 to DN 50 hose bores.<\/li>\r\n<li>Flange head with O-ring groove at the face, ready for standard Code 61 sealing.<\/li>\r\n<li>100% pressure tested at the factory, with batch records available.<\/li>\r\n<li>The interlock tail profile must be matched to a spiral-hose spec, not braided hose.<\/li>\r\n<li>Part of the HENGHUA SAE 3000 psi flange fittings program, with matching FL series split clamps, O-rings, and bolts available in the same shipment.<\/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><strong>Built for spiral-wound hose.<\/strong> The interlock collar engages the spiral wire layers during crimping, which makes this interlock hydraulic hose fitting the dependable choice for four- and six-spiral circuits where standard tails tend to slip.<\/li>\r\n<li><strong>Nominal 3000 psi Code 61 flange face.<\/strong> Like every code 61 flange fitting in the HENGHUA program, the head mates with standard SAE J518 \/ ISO 6162-1 split flange clamps from the FL series, and the size-dependent rating is defined by the standard.<\/li>\r\n<li><strong>Five flange sizes in one family.<\/strong> From 3\/4&#8243; to 2&#8243;, nine part numbers cover the flange-to-hose combinations used most on spiral-hose equipment, so one supplier can serve an entire fleet.<\/li>\r\n<li><strong>Corrosion protection matched to the environment.<\/strong> Trivalent zinc (96 h salt spray), zinc-nickel (720 h), or Dacromet (1000 h) is applied according to duty.<\/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 an Interlock Hydraulic Hose Fitting?<\/h3>\r\n\r\n\r\n\r\n<p>A flange type hydraulic hose fitting terminates in a flat-faced flange head instead of a threaded port. Two split flange halves clamp the head to a mating pad, which makes the joint compact, vibration-resistant, and easy to orient in the field. Flange heads come in two pressure families: Code 61 is the 3000 psi series and Code 62 is the 6000 psi series; code 61 vs code 62 hardware must never be mixed because the head, clamp, bolt, and pad dimensions all differ.<\/p>\r\n\r\n\r\n\r\n<p>Interlock adds a second idea to that flange head. Where a conventional tail relies on radial compression alone, an interlock flange fitting carries a collar that locks into the spiral wire reinforcement as the crimp closes. The result is a positive mechanical hold that resists pull-off under pressure surges, which is why SAE flange fittings for spiral hose almost always use an interlock structure.<\/p>\r\n\r\n\r\n\r\n<p>The 87313 series is the straight member of the 3000 psi interlock family. In the same family, 45 degree and 90 degree elbows are the 87343 and 87393 series, and 6000 psi and 9000 psi interlock lines are available for heavier duty classes. Every code 61 flange fitting in this interlock family shares one head geometry, so the clamps, O-rings, and pads interchange across the straight and elbow configurations.<\/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<p>Dimension letters follow the drawing printed on the data sheet: A, C, H, and S2.

Standard tails rely on radial compression and are not recommended for spiral-wound hose.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: Can the 87313 series be used with braided hose?<\/strong> A: No. The 87313 interlock hydraulic hose fitting belongs to the HENGHUA range of flange fittings for spiral hose. For wire-braid hose, order the matching Code 61 braided series (87311-XX-XX).<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: Is the 87313 Code 61 or Code 62?<\/strong> A: Code 61. As a code 61 flange fitting it follows the SAE J518 \/ ISO 6162-1 geometry with a nominal 3000 psi rating and must not be paired with Code 62 clamps or pads.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: How do I read a part number like 87313-24-20?<\/strong> A: 87313 is the series, 24 is the flange size in 1\/16&#8243; increments (1.1\/2&#8243;), and 20 is the hose dash (1.1\/4&#8243; bore, DN 32).<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: Does the fitting come with an O-ring and bolts?<\/strong> A: The flange head carries the standard Code 61 O-ring groove. O-rings can be supplied with the order; the split flanges and bolts are separate line items selected to the flange size.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: What working pressure can I expect?<\/strong> A: The flange connection is rated nominal 3000 psi Code 61. The finished assembly is limited by the spiral hose rating and the crimp, so always verify with the data sheet.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: What temperature range does it cover?<\/strong> A: Typically -40\u00b0C to +120\u00b0C. High-temperature or low-temperature systems should be checked against the hose and seal ratings first.<\/p>\r\n\r\n\r\n\r\n<p><strong>Q: Can HENGHUA make a custom version of this interlock fitting?<\/strong> A: Yes. Custom stems, surface finish, stainless material, and laser-marked part numbers are standard OEM options with a 24 h quotation response.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Request a Quote<\/h2>\r\n\r\n\r\n\r\n<p>Tell us the flange size, hose dash, hose spec (spiral-wound, with the brand and construction), and quantity, and we will confirm the 87313 code, price, and lead time within 24 hours. OEM buyers can add legacy part numbers or drawings for cross reference.
