Jacks of the same size can carry different brackets and still take the same cylinder.

On an SAE fitting there are no threads exposed between the cylinder body and the hex; on an NPTF fitting the threads are exposed. This cylinder has always been supplied with SAE fittings. If your jack has NPTF fittings, call EQ Systems at 800-846-9659 before ordering so the correct replacement fittings go out with the cylinder.\u003c\/p\u003e\u003ch4\u003eDocuments\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Hydraulic_Cylinder_Identification_for_Tube-in-Tube_Jacks.pdf\" target=\"_blank\"\u003eHydraulic Cylinder Identification for Tube in Tube Jacks (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/EQS1004R3-EQ-Systems-Commercial.pdf\" target=\"_blank\"\u003eEQ Systems Hydraulic Jack Options, commercial range (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Required-Maintenance-Items-Hydraulic-Systems-EQ-TM.pdf\" target=\"_blank\"\u003eRequired Maintenance Items for EQ Systems Hydraulic Jacks and Slide Systems (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EQ Systems","offers":[{"title":"Default Title","offer_id":43958754902075,"sku":"2505EQ","price":477.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/AJ-70-2505EQ-scaled.jpg?v=1786537079","url":"https:\/\/eqsystems.us\/products\/aj-70-cylinder","provider":"EQ Systems","version":"1.0","type":"link"}
