The Stovebolt Site Forums The Shop Area Engine Shop Push-on oil line fittings

I got some new flexible oil lines for my 261. They are a bit on the long side and I want to shorten them. They are made up of push-on hose and fittings (sold under Mr. Gasket brand, 1/2" NPT) supposed to be good to 200 psi. Can I just cut one of the fittings off, shorten the hose, and push it back on (after cutting the hose off the fitting) or are these one-time-use fittings?

Imperial brass and Gates and others make a "push on" hose system,use the proper hose with the proper fittings and they are reusable and permanant.If you don't feel safe not running a hose clamp,they don't need them,but you can moderately clamp it if you want.

4onthefloor, the push lock system works good for low pressure. I have been told it is better to not use a clamp on them. They are kind of like chinse hand cuffs, the more pressure the tighter they seal. Mike

I used pushlock on my air system to isolate the compresssor from the iron pipe and to run a flex line to the hose reel from the iron pipe. It seals tight and no problems at pressures to 175 psi so far.

Dont use a clamp - slomoe is right, the hose needs to try to "blow off" to pull the inner chords tight and provide effective sealing of the inner tube against the fitting.

If you cut it off (BE VERY CAREFUL TO NOT KNICK THE BARBS ON THE BRASS FITTING). Also, make sure you push it on all the way to the yellow ring as tight as you can so that when it is pulled on it has plenty of inner tubing to collapse in the valleys behind the barbs.

I worked for a Gates hose and fittings distributor when I was in highschool and saw some pretty wild applications where this stuff was applied (and mis-applied) It is good stuff when used in recommended applications.
