content: Can anyone ID the brass airline connection on the EFD900.In the image, the end nearest you is 6.28mm (dia) which suggests Imperial, yet the bulkhead nut on the rear of the connector is a perfect 14mm AF.I only know of ARO, TruFlate and Industrial Interchange, with TruFlate being the closest in appearance.

content: Yes, I agree, it certainly looks like the 1/4" variety, but the first shoulder in the part profile is much wider.

content: Measure it with calipers and make a sketch with the dimensions and post it. I will see if it matches either of the two styles I have in my shop. I looked on the EFD manual and it looks like it may be a freak size on purpose to lock you into thier filter regulator unit.

content: Look it up on the FESTO parts catalog, it is a standard part from them, and has many clones also available. It is a pretty standard airline fitting, which are interesting in having a mix of dimensions, metric piping ( and imperial as well depencing on the particular pipe and the spec of being either ID or OD toleranced) and threads that are mostly imperial, with just enough metric to confuse.

content: Measurements and an internal shot for those interested.I looked through the Festo catalog but no joy.This is such an oddball connector that I'm willing to change to 140psi polyethylene tubing and "prestomatic" connectors,though I'm undecided how to best convert from an female Industrial Interchange connection on the compressor.

content: Quote from: Bored@Work on April 02, 2013, 09:21:32 pmIt's a case of the need for a lightweight connection solution that won't pull the dispenser of the workbench as well as the porous nature of some airlines.

content: No match on any of my connectors. An easier solution is just get a length of 1/4" ID flexible air hose that you will use to feed it with any way and push it over the quick coupler and put a hose clamp on it that grips centered on the groove of the coupler.

content: Just replace it with a push fitting.http://www.parker.com/literature/Brass%20Products/Brass%20Product%20-%20Images/BUL.3501%20PTC-QRG.pdfThat way you don't need a fitting on the hose end it just pushes into the fitting.
