Topic tags/keywords: question air hose air compressor

I have a small Harbor Freight air compressor that I occasionally use to add air to a tire or power a nail gun. The air compressor, regulator, hoses, etc probably have seen less than 3 hours use since I installed the system about 4 years ago.

Recently, I needed to use my 23 gauge pin nailer and so I fired up the air compressor. There was a constant hissing of escaping air. It turned out to be from a bad air line connecting the air compressor to the regulator. The rubber is completely shot next to one connector, and is hard over the entire 3’ length.

I have since replaced it with a slightly longer hose. But, I am wondering what maintenance I should be doing to keep the hose from degrading in the future?

Here are a couple of pictures:

I have never seen a hose decompose like that in 4 years, so I’d attribute it to bad quality/materials. Hopefully your new one is of higher quality. I don’t know of any maintenance that needs to be done other than keeping it out of solvents and liquids in general. Oh, and avoid kinking it especially near the fittings.

Get a better hose. Legacy’s flexzilla hoses are amazing.

Do we no longer have any pride in our spelling? Jesus loves you anyway.

Most of those small compressors have a rubber hose connected to the pump output and going to the tank or a regulator.

I have a Porter Cable made the same way.

I have been expecting it to do just what yours has done because of the heat.

Thankyou for confirming my suspicions.

A reasonable fix would be to replace that section of hose with copper tubing; preferably with a loop to allow enough flexibility.

I was thinking of how people rub something on their dashboards and tires.

Teejk: no not exposed to sunlight

DKV: try typing on an e-book reader keyboard. Also, I don’t see anything about this topic what would imply that I am not acting like an adult.

Crank49: the compressor did not come with a regulator or hose. I added both of them from Harbor Freight. I went with a rubber hose so that I could move the compressor.

NiteWalker: I replaced it with a piece of Goodyear rubber hose. I hope that has a better life expectancy.

Hi. If it’s too near an electric motor like a furnace pump or blower it will degrade rapidly. Also, spraying with silicone spray or Armorall will increase it’s life.

dkv…I checked the spelling bee finals for the past several years and I didn’t see your name. I would guess that most people on this site are looking for help or are trying to help others and spelling/punctuation goes unnoticed (as they should).

Dave G…I remember the “ozone” thing from electric motors but I have had one of those wheel barrow compressors where the hose is always near the motor (30 some years now) and the hose is just fine (wish I could say the same for the tank).

The little pancakes regardless of brand come with a rather hard vinyl coating. Junk I think…replace with quality hose and good to go. Do remember to drain the tank though!

Given that it comes from HF it’s possible the hose is made from natural rubber , making it much more susceptible to
deterioration.

teejk – yes bit of a puzzle since modern times I haven’t seen rapid deterioration. Probably Jim’s hit the nail.

Nothing you did, hose quality I assume. ALTHOUGH someone once said that if you kept anything rubber in a garage with a fridge or freezer that it would deteriorate more quickly due to off gassing from the compressor. I didn’t think a closed system like that would off gas, but your mileage may vary.

Interesting that it is worse in the one section near the end.

DKV – - – - What the hell is wrong with the spelling? I saw a couple of typos in the OP, but nothing I thought needed pointed out. Something I’m missing? Or are you perfect….........?
