Since when

I've always tried to grab them on Amazon Prime.
They usually go for a fraction of the price the other places sell them for.

Also - Keep an eye on the thread types that they're using..
They should be listed as either BSPP or NPT.

NPT for USA and BSPP for just about every other place in the world.
The two are not compatible / interchangeable, so just be careful when ordering.

This is one of my pet gripes with this industry and our suppliers. The price they charge for air hoses, fittings and o-rings is an embarrassment. I don't mind paying for good stuff and everyone is entitled to make a profit but in this case its just abusive. On an order a short time ago had a well known supplier include a couple of fill hoses. Didn't ask the price. These are my friends. 60.00 each. 120.00 for 2. Bought half dozen a while back imported and they were around 15.00 each. Ended up giving them away over time to friends in need and not one that I know of has failed. Just goes to show, always ask the price. Sylvan
