Just a thought or two, after talking with DH Engineer, Mike Montgomery, their connection nuts are 9/16" across the flat and right at 5/8" across the corners.  It takes a 5/8" hole to get the nut thru.  The Nylon/Kevlar/Nylon line itself is 4.9 mm O.D.-- 2.0 mm I.D.  It is crimped hydraulically and swedged at its tip onto the mandrel.  No way to do this in the field.  DH will do a Swedgelok (sp?) end, will not test it and its still a bit more that 1/4" on the upset.  SOOO for a bunch us with the Nylok tuning ( and shiethed in 0.132" O.D. Tygon or other)  it's time to consider something else.. The guys at Lancair still recommend the Nylok and mine has been well shiethed and in service for 19 years.  So, group what else is there ???   AOG    Don Skeele    N320J
