{"product_id":"tecline-r4-tec-first-stage","title":"R4 Tec First Stage","description":"\u003ch4\u003eDescription\u003c\/h4\u003e\u003cp\u003eA decompression stage hangs at the diver's side for the whole dive, so a smaller, lighter first stage makes the cylinder easier to trim and to handle on the surface. The R4 TEC is Tecline's compact diaphragm first stage, 637 g in chrome-plated marine bronze, with a dry chamber and cold kit for cold water and a 9.0 bar intermediate pressure. Tecline rate it perfect for stage cylinders, well suited to a twinset and good on a single tank, and they do not recommend it for sidemount, where the fixed port layout gets in the way. Its four LP and two HP ports are placed without a turret, which keeps the body short under a stage valve. The standard version takes a DIN 300 bar connection. The O2 version carries a DIN connection with an M26x2 thread for oxygen-valve cylinders, the usual choice for a shallow decompression stop. Both meet EN 250A. It suits a technical diver setting up stage or decompression cylinders, or a twinset diver who wants compact first stages.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType: balanced diaphragm first stage, compact body\u003c\/li\u003e\n\u003cli\u003eConnections: DIN 300 bar, or O2 version with M26x2 DIN connection\u003c\/li\u003e\n\u003cli\u003eIntermediate pressure: 9.0 bar\u003c\/li\u003e\n\u003cli\u003ePorts: 4 LP and 2 HP, fixed layout\u003c\/li\u003e\n\u003cli\u003eFreezing protection: dry chamber with cold kit\u003c\/li\u003e\n\u003cli\u003eMaterial: marine bronze, chrome plated\u003c\/li\u003e\n\u003cli\u003eWeight: 637 g\u003c\/li\u003e\n\u003cli\u003eStandard: EN 250A\u003c\/li\u003e\n\u003cli\u003eRecommended by Tecline for: stage first, then twinset and single tank; not for sidemount\u003c\/li\u003e\n\u003cli\u003eSecond stage and hoses: sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003eR4 TEC first stage in the selected connection\u003c\/li\u003e\u003c\/ul\u003e","brand":"TECLINE","offers":[{"title":"DIN 300 bar","offer_id":67575231447353,"sku":"T01410-1","price":5115.0,"currency_code":"ZAR","in_stock":true},{"title":"O2 M26x2","offer_id":67575231480121,"sku":"T01410-3","price":4823.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/1730\/8473\/files\/i-szy-stopien-r4-tec-en250-2014.jpg?v=1790773687","url":"https:\/\/scubaevolution.co.za\/products\/tecline-r4-tec-first-stage","provider":"Scuba Evolution","version":"1.0","type":"link"}
