Polyurethane Air Hose Help!

[Peter Pedisich]

Hi,

I cannot find in any of my magazines or online if it is ok to mend/splice a polyurethane air hose with the barbed end fittings and hose clamps I've always used for rubber air hose?
I have a 3/8" I.D. Bostich ProzHoze.

Thanks for any help!

I don't know if its ok or not but I have been using this type of splice for years and never hard a problem with them.

Bill,

Thanks, that looks interesting. I've always used these (below) and they snag on everything, including skin!

Hi, anyone know where I can get a connector like Bill shows?
my local hardware store did not have one.

Thanks!

Bostich has a repair kit for your hose. It's kind of expensive though.

I suspect that any 3/8" tubing, compression fitting, union will suffice.

Those would work just fine, they are brass so they should never rust and I think they are better then the steel ones.

I hear you with regards on the hose clamps possibly snagging on things. So, consider checking with a machine shop or hydraulic hose repair place to have them crimp a smooth metal lock around the hose repair barb/splice that you buy, instead of using hose clamps. The metal locks/sleeves are used to lock rubber hoses and other hose materials over the barbed fitting of whatever fitting is wanted at the end of the hose. As long as your hose outer diameter fits a sleeve that's standard, you only need to track someone down that has the heavy duty crimping tool and sleeves in stock to pop it all tight for you. Here's a link to the type of tool I'm talking about, http://www.mcmaster.com/#barbed-hose-fittings/=9sdozl .
There are cheaper manual ones, but most commercial hose places will use something more robust like the above one, or even better made ones since they do this all day long. Worth a look into if you're dead set against having hose clamps to hold your barbed fittings tight to the hose.

a couple things should be done. One, you CAN over-tighten the hose clamps, and still get a leak that way. Two, use a length of old rubber hose that will fit over the slice, that way the slice won't hang-up on everything as it moves around. At my "day job", we used a "slip-fit" connector made for that type of hose. There is a ring that will snug up the hose after you push a hose onto the connector. One moves the ring back, presses the hose on, and then push the "locking ring" back in place. I think we get these at either Grainger, or McMaster-Carr. I 'll check this weekend when I go back in to work.

I hate to say this, but both HD and Lowe's carry the brass barbed and the plastic quik-fit fittings mentioned in this thread. May not be the most economical, but they do have them.
