The smooth power of a big block…

[Magnum Man]

In hot rods, I was always a big block fan…
So, I had been having a lot of issues with air lines, blowing off their fittings, this was while I was running one of the cheaper piston pumps… but I’ve now switched to a “big block” with my new air pump, and it’s too early to really pass judgement, but the new better quality piston pump, while putting out more air, maybe is more volume, but less pressure??? Or is smoother in it’s output… it seems to be anyway, maybe my air line issues are over, and it was the fault of my previous pump???

I get hoses blown off filters all the time. It isn't the pumps. It's the hosing. Silicone airlines are the worst for it.

You could do what they do for hydraulic systems and add an accumulator to even out the pressure. For a compressible gas like air you just need to have a volume of air closed off but attached to the air line. When pressure will still vary with each stroke of the piston but it is acting on a larger volume of air so the swings in pressure would be smaller. Might make it easier for your airlines.

Cut a 1/2 inch of hose, stretch it a little with long nose pliers and put it over the end of the hose where it connects to your stuff. It double the thickness where the hose meets your equipment and give a much stronger grip.

My pumps (I have 2 linear pistons running) feed into 3/4 pvc that runs around the room in a 24 x 12 foot loop. I have 70 air valves drilled into it (60 in use), with airline descending from the loop. The only area I have problems is the airline to underwater device connection. really old airline that has become rigid lets go, but so does black and opaque silicone tubing. For whatever odd reason, I have less trouble with blue silicone airline. I assume different manufacturers, but it all came as no name.
