Compression fitting torque?

Kenneth · #1 10-22-2006, 11:31 AM

Hi all,

I'm in the process of putting together my first tank and am about ready to start permanently attaching some of the vent lines, pick-up, etc. but I have been unable to find a reference on how much to properly torque the compression fittings.

I thought I heard at one time to finger tighten them, then one more face of the nut, but I can't confirm that.

Anyone have the specs or know what is appropriate for these fittings?

Thanks in advance,
--Ken

Don't know the torque, but these are NOT compression fittings, but rather flared couplings. I say this only to help ensure that others give you what you need.

In Van's SB (here) about safety wiring the nuts on the pick-up tube are the following torque values :

AN818-4D : 50-65 in.lb
AN818-6D : 110-130 in.lb
