The design also guarantees that at least one disc will always remain tight to the pipe wall creating a 100% seal. The discs are UV and temperature-resistant up to 330ºC for up to one hour. The gas is diffused into the chamber via the built in sintered diffuser and exits through the exhaust holes in the secondary twin disc unit. This process of gas diffusion provides an even flow of gas and prevents any gas turbulence behind the weld, thereby minimising the risk of oxygen in the welding chamber while, at the same time, achieving an extremely short purge time. \u003cspan\u003eThese extremely short purge times result in valuable cost savings in gas and time.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eBesides the very short purging time, the Silicon Seal System also offers the possibility to cover various nominal pipe diameters by one pair of baffles enabling highly economic use of the device. The double seal system can be purchased individually or in kit form for a range of pipe diameters. Gas inlet push fitting universal on all sizes.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words\"\u003ePurges pipes in under 2 minutes with minimal gas usage\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words\"\u003eGuaranteed gas tight seal with twin silicon discs\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words\"\u003eFits pipes 16-38mm diameter (kit covers multiple sizes)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words\"\u003eTemperature resistant up to 330°C continuous use (450°C for short periods)\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words\"\u003eWorks on pipes, elbows and fittings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GBC","offers":[{"title":"KDSF16mm-18mm Double Gas Finger","offer_id":55458198225272,"sku":null,"price":32.98,"currency_code":"GBP","in_stock":true},{"title":"KDSF19mm-24mm Double Gas Finger","offer_id":55458198258040,"sku":null,"price":34.02,"currency_code":"GBP","in_stock":true},{"title":"KDSF24mm-29mm Double Gas Finger","offer_id":55458198290808,"sku":null,"price":35.14,"currency_code":"GBP","in_stock":true},{"title":"KDSF29mm-34mm Double Gas Finger","offer_id":55458198323576,"sku":null,"price":36.18,"currency_code":"GBP","in_stock":true},{"title":"KDSF34mm-38mm Double Gas Finger","offer_id":55458198356344,"sku":null,"price":37.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0515\/8305\/8084\/files\/SFE_DSS_005_TAB-Quick20Preset_600x600-large.webp?v=1771498086","url":"https:\/\/www.brooksideweldingsupplies.co.uk\/products\/gbc-double-seal-gas-finger-sizes-16mm-38mm","provider":"Brookside Welding Supplies Ltd","version":"1.0","type":"link"}
