White PTFE tape is not rated for gas service, degrades under gas exposure, and can cause slow leaks that are difficult to detect. Yellow gas tape is thicker, denser, and specifically formulated to seal gas threads. Apply 2–3 wraps in the direction of the thread, then test every joint with soapy water after restoring gas flow.\n\u003c\/div\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/images_6_53cc9a60-cc6c-4e51-b38d-6f3f39bb809e.jpg?v=1781886405\" style=\"width:600px;max-width:100%;display:block;margin-top:24px;border-radius:10px;\" alt=\"Brass Nipple 3\/8 inch — QD-GMN6-6F Propane Gas Fitting\"\u003e","brand":"XPart Supply Ltd.","offers":[{"title":"Default Title","offer_id":52868983947553,"sku":"QD-GMN6-6F","price":29.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/7783\/2225\/files\/images_6_53cc9a60-cc6c-4e51-b38d-6f3f39bb809e.jpg?v=1781886405","url":"https:\/\/xpartsupply.com\/products\/brass-nipple-3-8","provider":"XPart Supply Ltd.","version":"1.0","type":"link"}
