The cylinder features a built-in, double-acting pump that delivers oil when the handle is both pushed and pulled. This moves oil through the system twice as fast as single-acting pumps on other integrals. Assemblies include a hardcoat-anodized aluminum cylinder and pump, valve, and stainless pump handle with three attachment options: pin installs handle permanently; O-ring secures handle in socket, but is not permanent; nonlocking handle installs without O-ring and roll pin. All pins and plugs are stainless steel. Cylinders include a clevis on both ends. Standard eye-jaw toggles fit all Harken® cylinders. The pressure release knob turns clockwise to close and pump, counterclockwise to release. When closing the pump, the knob cannot be over-tightened by hand, preventing damage to the valve. Release speed depends on how far open the knob is turned. Pressure relief is factory set to prevent crew from over-tensioning the backstay.\t\u003c\/p\u003e\n\u003cdiv id=\"gap-2049057795\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\"\u003e\n\u003cstyle\u003e\n#gap-2049057795 {\n  padding-top: 30px;\n}\n\u003c\/style\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"container section-title-container\"\u003e\n\u003ch3 class=\"section-title section-title-center\"\u003e\n\u003cb aria-hidden=\"true\"\u003e\u003c\/b\u003e\u003cspan class=\"section-title-main\"\u003eProduct Specifications\u003c\/span\u003e\u003cb aria-hidden=\"true\"\u003e\u003c\/b\u003e\n\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cp\u003e'- Size -12\u003cbr\u003e\nMaximum wire Ø (mm) 8 mm\u003cbr\u003e\nMaximum wire Ø (in) 5\/16 in\u003cbr\u003e\nStroke (mm) 385 mm\u003cbr\u003e\nStroke (in) 15.2 in\u003cbr\u003e\nPin center length (closed) (mm) 832 mm\u003cbr\u003e\nPin center length (closed) (in) 32.8 in\u003cbr\u003e\nWeight (kg) 4.92 kg\u003cbr\u003e\nWeight (lb) 10.8 lb\u003cbr\u003e\nGap\/pin Ø (mm) 15.9 mm\u003cbr\u003e\nGap\/pin Ø (in) 5\/8 in\u003cbr\u003e\nPull force @ 1000 psi\/69 bar (kg) 952 kg\u003cbr\u003e\nPull force @ 1000 psi\/69 bar (lb) 2098 lb\u003cbr\u003e\nPull force @ 2000 psi\/138 bar (kg) 1904 kg\u003cbr\u003e\nPull force @ 2000 psi\/138 bar (lb) 4197 lb\u003cbr\u003e\nPull force @ 3000 psi\/207 bar (kg) 2855 kg\u003cbr\u003e\nPull force @ 3000 psi\/207 bar (lb) 6295 lb\u003cbr\u003e\nPull force @ 5000 psi\/345 bar (kg) 4759 kg\u003cbr\u003e\nPull force @ 5000 psi\/345 bar (lb) 10492 lb\u003cbr\u003e\nBreaking load (kg) 9518 kg\u003cbr\u003e\nBreaking load (lb) 20984 lb\u003cbr\u003e\nFootnote Max relief setting is 5,000 psi \/ 345 bar.\u003c\/p\u003e","brand":"Harken","offers":[{"title":"Default Title","offer_id":51625693315409,"sku":"HKN-HCI012BCC","price":3695.57,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4434\/4913\/files\/www.sailrace.com-harken-12-integral-backstay-cylinder-40mm-bore-385mm-stroke.jpg?v=1754726608","url":"https:\/\/www.sailrace.com\/it\/products\/harken-12-integral-backstay-cylinder-40-mm-bore-385-mm-stroke","provider":"SailRACE","version":"1.0","type":"link"}
