Need information about air hoses and connectors

Factual Questions
1

I recently bought a Viair 300P air compressor for off-roading in my Jeep - VIAIR® Corporation – 12-Volt & 24-Volt Air Compressors and Tire Inflators | Your Vital Air Source

It connects directly to the battery terminals under the hood. In general it works very well, but the included power leads are too short, and the coiled air hose is too stiff. As a result, it cannot reach the furthest tire from the battery.

I could get a pair of jumper cables and use those as a kind of extension, but I would prefer to extend the air hose.

The compressor itself has a quick connect coupling like the one pictured in the following link: VIAIR® Corporation – 12-Volt & 24-Volt Air Compressors and Tire Inflators | Your Vital Air Source . The air hose has a corresponding female connector. I would like to buy another hose (preferably not coiled) that is compatible with these quick connect fittings so that I can use it as an extension when needed.

My questions:

  1. Is this quick-connect fitting any kind of a standard part or do I need to order the extra connectors from the manufacturer?
  2. Most air hoses I’ve seen online come with male or female threaded NPT fittings already attached. If I buy a hose but want to shorten it, can I attach the NPT threaded connector myself using normal hand tools or do I need a special tool (e.g. a crimper)?

Those are standard parts. Available at most hardware and automotive stores.

You can crimp your own hose, but it’s kind of pointless, the next thing you do will be a little further away than you expected.

If you have a rubber hose you can probably find threaded fittings with a barbed end that slip into the hose. Simply use a worm type hose clamp to seal. Your quick connect fittings will then thread onto these.

They also sell self coiling air hoses that may suit you. I don’t like them as the air chuck disappears at high speed as soon as you let go. :eek:

the premade coiled plastic hose take up very little space and store themselves. you do need to hang on to them if extended.

you can shorten a rubber hose as **GaryM[\b] stated but the hose clamp is something to snag on.

They don’t snag if you cover the hose clamp with some adhesive filled heatshrink tubing. The self adhering silicone tape works good too.

Bring one of your attachments or the hose in to the store as there are several different styles and I can’t tell what yours is by looking at a picture. the styles are “T”. “M” and others.
I do crimp on ends also just like to original.
And the worm hose clamps are not the best, get the fuel line clamps if there is a choice at the store. The fuel line clamp is on the Left.and these crimp on’s are good, and takes aspecial crimping tool, same tool crimps bands on CV boots.
and I also use style Ferrel collarswhen repairing air and torch hoses. this is the crimping tool for the Ferrel, I have the cheap one that is used in a vice.
