Hi guys

I received yesterday, a nice brand spanking new air hose to go with my recently upgraded air compressor. Unfortunately, it turned up damaged as per the below picture.

Now I contact the ebay seller and i'm sure they would sort me out with a refund, but the pipe was £17.50, by the time i've shipped it back, and they've deducted postage of the replacement, it's almost not worth the hassle!

So, question is, can this be easily repaired at all? Can I buy a couple of new better quality fittings from somewhere and trim the ends off the pipe and put two beefier one's on?

That looks like 1/4" NPT, if that is the case it is not ideal for an air hose as it does not swivel.

In answer to your question, yes they can, but are likely to cost much more again to fix that replace.

Hmmmm ok. I'll double check tomorrow but I think it swivelled.

It arrived like that anyway so I assume damaged in transit somehow.

I will try and return for as much as I can get back and replace then.

Thanks

Certainly you can. You just need to cut the old fitting off the hose and fit one of these, secured with a jubilee clip.
Measure the ID of the hose to get the correct size barb. You can buy them on Ebay or perhaps somewhere like Machine Mart or Cromwell could help you.



Below is one that swivels.

That fitting you have looks like Chinese crap, I wouldn't trust it under pressure, a failed air hose is like a whip and the air blast from a failing one can seriously injure you and introduce air bubbles into your bloodstream which can be at best painful and at worst fatal!

If it's just for hobby use, I'm not sure how long the one you have is, but there is this 10m 3/8" hose for £14.39 from Machine Mart which would be safer, cheaper and warrantied with a shop you can goto!

Rich is correct. Compressed air can be dangerous and should be treated with respect. But a lot of what Machine Mart sells could also be classed as 'Chinese Crap' which is why it's relatively inexpensive.
A correctly assembled and maintained air hose shouldn't come apart but if you want to put your health and safety hat on, you could fit one of these 'Whip Checks' across each coupling: -



They stop a parted hose flailing around like an angry snake. Many industries insist on their use.

Thanks for the advice everyone.

After a complaint about the quality of the fitting, the company has given me a refund and told me to keep the hose. So, I'm going to buy some of those barb/ 1/4bsp fittings and make it good again.

To avoid 'Chinese crap' where should one buy these from? I want swivel for sure as its for air tools so constantly on the move. Not many swivel ones on eBay and not sure if they can be trusted now!!

Anyone recommend a good online supplier of the swivel type, 10mm dia and 1/4" bsp, male or female doesn't matter I have quick couplers for both. smile

Plenty to choose from here. https://www.cromwell.co.uk/shop/fluid-power/coupli...

Screwfix also stock some.

It's still worth a trip to Machine Mart if you have one nearby. What they have is probably fine for home use and you'll be able to see exactly what you're buying. PCL is a manufacturer that springs to mind. You still need to measure the inside diameter of your hose for the correct barb size, but I'm guessing 3/8".

The pipe was sold as ID 10mm, so in working off that. It seems a bit harder to find swivel ones.

Opinions on using non swivel barb connectors? Fine for home use? Compressor is a 10 bar 150l jobbie

3/8" = 9.525mm so a 3/8" barb fitting will be fine for your hose if you can't find 10mm.

What type of 'quick connect' couplings are you using on your air tools? The straight push-in type freely rotate when connected. You only really need an additional swivel fitting if using the bayonet type of quick connector.

Edited to add: http://www.ebay.co.uk/itm/Pack-of-2-Hose-Barb-Air-... an example of a 10mm Barb to female Quick Coupler (negating the need for an additional BSP connection).

I'm using those snap style couplers, but with bsp threads! I'll pick those up and the corresponding for the other end of the hose.

Most air lines would have a quick release system, there are various types, and I prefer to attach these with "lemon" or "O" clips.
These tend not to get hooked up on things when in use unlike a screw (jubilee) type.
They tend to crimp onto hose tails so much better and are a permanent fix.

I did specify "for hobby use"!

The crimped fittings are definitely preferable to Jubilee clips too as stated above thumbup

Thanks everyone

I have on the way 2 x Femaile snap adapter in the correct barb, 2 x Maile snap in correct bard and a selection of those crimp clips.

I think i'll turn my 15m hose into 2 x 7.5m and join them when i really need 15m (not often). The 15m looks like it might be a bit unwieldy to handle!!

Easy they said

Get some of these barb fittings they said hehe

Well, barb connectors arrived, and I can't get them on for love nor money. I've heated the air hose by soaking in boiling water, tried some washing up liquid and even tried brute force and ignorance, NOTHING!!

I can get them on to about half way down the barb and they won't budge. I've measured (with my vernier) the ID of the hose and it is indeed 10mm, the barb connectors state on the packet they are for 10mm

So, how the hell do i get them on easily? My hands hurt too much right now to care, so they are in the garage having a word with their-selves!!

leave in a jug of boiling water for 3-4 minutes then press the connector on the floor or suitable surface (bit of wood is best as its less likely to slip).

They are designed to be a reasonably tight fit!

Did you miss the bit where i said boiling water was tried?? I pulled the lid on my garage kettle for 5 minutes and kept it boiling hehe

That and some oil on the fitting, and washing up liquid, and half an hour up pushing in, removing, clearing debris and i've got ONE of the four in!! The crimps only arrived today so i guess i will attack the bloody things tomorrow. biggrin

If you are warming the pipe but not the barbed fitting then this could be why your only getting it on half way.

The metal fitting will take the heat from the soft squishy pipe quite quickly and leave you pushing a soft pipe that has hardened
and shrunk onto the first part of the barb. Dangle the fitting only into the boiling water and let the heat travel into the pipe.

At the risk of stating the obvious, don't forget to slide the clips onto the pipe first. wink
