Sorry about the pic-----but it does show the OE hoses that Vans had on the RV12. Stratoflex 124 with 524 and 528 stainless hoses ends. Note the stamped AN nuts. The Rotax provided hoses were rubber lined pushlock hoses like the second pic. Steel fitting, some were metric threads with DIN ball seat connections. To my knowledge, Vans always used teflon for the oil system. Early on, Rotax supplied the fuel system, which was rubber pushlock under the firesleeve--hence the 5 year replacement SB. All have since changed to teflon.
TS Flightlines, Aircraft Specialty, and now AS Flightlines Joint Venture has always used teflon.
If anyone has trouble identifying what they have---give us a call.
AND---dont get fooled by a data tag on the firesleeve on an obvious old hose. Yep, its been done that some guys removed the firesleeve and data tag and reinstalled it on 'other' hoses. And, just because you pull the firesleeve back and it has a stainless braid hose underneath, it 'could' be a 701/156 style hose with a rubber liner, or an imposter hose that is a lookalike 701/156 hose from one of the race car hose suppliers. Teflon hose, if not damaged by rubbing on something will outlast the life of the airframe.
