I was digging around the shop last night and found a large spool of rubber air hose I forgot I had. What options are there for making quality airlines? I've used the standard hose barbs and metal hose clamps in the past, but I hate the metal clamps on the ends, they snag on things and can be rather sharp and get in the way, plus they are ugly!

What is out there that can be done at home that will give a high quality result? I found some hose barbs that dont require clamps, but they say they are for a specific type if hose? What options do ai have?

I have about 500ft of hose and want to me a few diffrent sizes and want them to hold up.

I saw those earlier but couldn't find anything about use with pressure? Those would be perfect if they will work??

I don't know. I want to try them, but haven't gotten around to it. I can get a 10 pack for $18 shipped off of Rock Auto. They have great reviews, but are onetime use only.

You can use single or double ear hose clamps which are a lot smaller. https://www.simplyplumbing.com/2560.../cgi-bin/einstein.pl?::1:WLDWH:1:320=10100011

I think you can also use pex tuning rings, but the easiest thing is to bring it down to your local NAPA or hydraulic hose supply shop and have them crimp/clamp the fittings on with hydraulic hose crimpers. Most times they do it for free or just a few bucks.

I have used the screw-together fittings and the Gates heat shrink radiator hose clamps to repair air hoses.

The screw-together fittings (as suggested by JJThrasher) must be closely matched to the hose ID and OD. If the hose is old and starting to break down, these will not hold for long. They work best on new, high-quality hose.

I used the heat-shrink clamps in conjunction with the hose barbs that are supposed to not need clamps. I figure that this is a "belt and suspenders" sort of installation. Most brass ferrules are very thin, so the plastic clamp rings should be nearly as strong. I like the plastic rings because they are less likely to scratch things than metal ferrules.

You can buy crimping tools and brass ferrules from your local welding supply or off the internet. They vary from simple form blocks you clamp with a vise on up to purpose-built production tools. The problem for most of us is that the hose can vary in OD depending on the manufacturer, hose material, and pressure rating.

At times I have had to use worm-screw hose clamps on air hose ends. I cover them with heavy heat-shrink tubing that I get from an electrical supply house. This tubing has thicker walls and shrinks far more than consumer grade heat shrink. I buy 3M brand.
