{"product_id":"warhead-fill-valve-o-ring-set-4-pieces","title":"Warhead Fill Valve O-Ring Set (4 Pieces)","description":"\u003cp\u003eThe Warhead fill valve o-ring set offers a replacement o-ring for use with airsoft gas blowback (GBB) magazines.  Many fill valves have a tiny o-ring around them to prevent the loss of gas when filling the magazine.  If gas leaks when filling your mag, this could result in your magazine freezing-up, not to mention the loss of gas.  If your magazine never had an o-ring, try one.  We think you will be pleased.\u003c\/p\u003e\n\n\u003cp\u003eTo install the o-ring, slip it over the intake valve's fill tube.  This can be done by gently placing the o-ring onto a round toothpick and then aligning the toothpick with the intake valve's fill tube.  Slide the o-ring off the toothpick and onto the intake valve's fill tube.  The o-ring can then be pushed, using a can of green gas or a propane adapter, to its final position .\u003c\/p\u003e","brand":"ASA","offers":[{"title":"Default","offer_id":17128894267482,"sku":"27b07717-711f-4d53-a016-89556c297292","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0063\/4526\/1146\/products\/67415-2.jpg?v=1571718134","url":"https:\/\/airsoftgrounds.myshopify.com\/products\/warhead-fill-valve-o-ring-set-4-pieces","provider":"Airsoft Grounds","version":"1.0","type":"link"}
