Re: Fuel Line
Hi albgar,<br /><br />I have posted a reply I made to a previous post on the use of teflon tape which may be of some interest to you, if the correct type of tape is not easily available (should be) a suitable paste or liquid type sealant also rated for gas use would be available.<br /><br /> posted August 26, 2003 10:56 AM <br />--------------------------------------------------------------------------------<br />Hi CastawayRay,<br /><br />Having previously been in the plumbing trade for 33 years, I have to advise you not to use the standard teflon (treadseal) tape as it is NOT suitable for use with petroleum based materials such as propane gas, natural gas or liquids such as petrol and other refined spirits. As OutboardJim has noted it will start to break down and become sticky before eventually dissolving, you should use an approved (gas or liquid) thread sealing compound or if you talk to your local hardware store you can buy a type of treadseal tape that is approved for gas fittings. An extract from the regulations for materials use in the industry states “commercial PTFE (teflon) tapes are not suitable or approved for gas or petroleum based derivatives service”, it goes on further to state an approved teflon theadseal tape (Dupont trademark) must be used in this situation.<br /> In Australia this tape is a yellow colour and is specifically approved for gas use and is suitable for use on fuel fittings and connectors, it generally is only slightly more expensive than standard teflon tape.<br /><br />Accident investigations in Australia into some gas and fuel explosions have consistently found the cause was often linked to the use of the incorrect tape and it is now part of the regulations outlawing the use of incorrect teflon treadseal tape on anything but water supply installations.<br /><br />Bob
