1/4 pressure hose

[Bricks]

Hey there!
This is the first time I’ve had to replace a bay hose. It’s been over 10 months and I want to stick with what I’ve got. Where do you find a 1/4” Parker hose with male ends 15’ from the first thread to the last?
I had a spare made last summer and it’s the rough texture hydraulic style. After much consideration, I wouldn’t want to drag it across my cinder grit covered car, and the smooth texture might save it from catching mirrors. Thanks

Parker is a brand name and can be pricey.

I have swapped to the mosmatic comfort hose. They're relatively expensive but light and easy to handle.

I messed up. It’s 3/8” ends.

Yes they are lite and easy to move around the bay. At first we really liked them. However we find many get a kink in the hose after just a few months. We are using up our spares and returning to the traditional hoses. Continental.

Interesting, Mine are over a year old and so far I haven't noticed that. I'll take a closer look at them.

We have been using the Mosmatic hoses for almost two years and really love them. When new they have a lot of memory and kink up a little bit. After a few months they are great. Very light and flexible. My theory is that the hot water gets the memory out. We have swivels at both ends of the hose so that might help with these hoses. The only one we have replaced so far was for cosmetic purposes from "The Great Seal Coater Incident".

My mosmatic hoses have also kinked in a few spots. I was real concerned with them kinking and not letting weep water flow that would end up in a frozen line. But this last winter I did not have one freeze problem in 11 SS bays.

Hey all, I have always used 3/8 hoses. What is the advantage of 1/4" ?

Quicker chemical changeover.

Do you run 1/4" from your pumps the whole way to the gun? Or just the last 12 or so feet?
If it's just the last few feet you're only talking about a couple of ounces of hose capacity.

Mine have not been changed to 1/4 yet. I think every ounce counts. I’ve seen many customers stand and wait for the lines to clear.

Something to note if you haven't thought of it...A .25" ID hose will lose 207 PSI on a 75' run. A 3/8" ID hose loses 30 PSI for the same 75' length. So, in order to get the proper PSI at the wand, your equipment/pumps will have to work harder with .25" ID hose...

It helps more with the low pressure function switch over time that are teed above the bay. We are still using 3/8" all the way but I always wanted to try a 1/4" bay hose with a pressure gauge at the tip and compare to 3/8".

I used 3/8" from pump to boom, then 1/4" from the boom manifold to the gun. The smaller hose is easier for the customers to handle, and of course the changeover time. The volume of a 3/8" hose is more than double that of a 1/4" hose.
