In 2008 Poseidon updated their Xstream first stage design (the Mk3 designation) and Xstream\/Jetstream second stages to no longer require a Poseidon-specific low-pressure regulator hose.\u003c\/p\u003e\n\u003cp\u003eThis adapter allows use of standard regulator hoses with Poseidon second stages manufactured prior to 2008. However, you MUST include an over-pressure relief valve, either by adding an OPV to an unused LP port on your older (Pre-2008) Xstream first stage - OR - use a current (manufactured 2008 and later) Xstream first stage that already incorporates an OPV.\u003c\/p\u003e","brand":"Poseidon","offers":[{"title":"Standard","offer_id":67635421937773,"sku":"0000-130","price":21.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/1302\/5133\/files\/oh-equipment-a439145de764569f80ef9694.webp?v=1791235476","url":"https:\/\/openwaterhabitat.net\/products\/poseidon-2nd-stage-hose-adapter-chrome-0000-130","provider":"Openwater Habitat Scuba","version":"1.0","type":"link"}
