{"product_id":"tecline-r4-tec1-21-o2-g5-8-stage-set","title":"R4 TEC1 21% O2 G5\/8 Stage Set","description":"\u003ch4\u003eDescription\u003c\/h4\u003e\u003cp\u003eA slung cylinder is easier to trim and to carry up a boat ladder when the regulator on it is small, which is why a compact first stage suits stage work. This is Tecline's R4 TEC1 stage set in the 21% O2 version, on a standard G5\/8 DIN connection. The R4 TEC, which Tecline rate perfect for stage cylinders, is a 637 g balanced diaphragm with a dry chamber and cold kit and no turret, keeping the body short under the valve. It feeds a TEC1 second stage, pneumatically balanced with venturi and breathing resistance knobs and a heat exchanger, on a 1 m black Proflex hose, all to EN 250A and in a Tecline bag. The second option adds a 52 mm pressure gauge on a 0.20 m Proflex HP hose. That covers a bail-out cylinder on a deep recreational dive, a travel stage on a cave dive and a pony on a cold wreck. It suits a diver who wants a light, compact regulator for an air stage or pony cylinder.\u003c\/p\u003e\u003ch4\u003eFeatures\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFirst stage: R4 TEC compact balanced diaphragm, dry chamber and cold kit, 4 LP and 2 HP ports, 637 g\u003c\/li\u003e\n\u003cli\u003eConnection: DIN G5\/8, 300 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eIntermediate pressure: 9.0 bar\u003c\/li\u003e\n\u003cli\u003eSecond stage: TEC1, pneumatically balanced, venturi and breathing resistance knobs, heat exchanger, 250 g\u003c\/li\u003e\n\u003cli\u003eHose: 1 m black Proflex LP hose\u003c\/li\u003e\n\u003cli\u003eWith SPG option: 52 mm pressure gauge on a 0.20 m black Proflex HP hose\u003c\/li\u003e\n\u003cli\u003eTecline designation: 21% O2 stage set\u003c\/li\u003e\n\u003cli\u003eStandard: EN 250A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR4 TEC first stage\u003c\/li\u003e\n\u003cli\u003eTEC1 second stage, black\u003c\/li\u003e\n\u003cli\u003e1 m black Proflex LP hose\u003c\/li\u003e\n\u003cli\u003eTecline regulator bag\u003c\/li\u003e\n\u003cli\u003eWith SPG option: 52 mm pressure gauge and 0.20 m black Proflex HP hose\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TECLINE","offers":[{"title":"Without SPG","offer_id":67575269032249,"sku":"10003-91","price":8548.0,"currency_code":"ZAR","in_stock":true},{"title":"With SPG","offer_id":67575269065017,"sku":"10003-93","price":11289.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/1730\/8473\/files\/automat-r4-tec1-21-o2-g5-8-zestaw-stage-en250a.jpg?v=1791645677","url":"https:\/\/scubaevolution.co.za\/products\/tecline-r4-tec1-21-o2-g5-8-stage-set","provider":"Scuba Evolution","version":"1.0","type":"link"}
