Wand Valve O-Ring size

[Dkane]

Hi,
Could anybody tell me what size the o-rings are on the plunger of the wand valve on the Hydramaster Hydrahoe wand? I mainly need to know the larger one, but knowing both would be great, too. Thanks.

Just buy a rebuild kit.
They generally make valves with non standard o rings.

I haven’t seen them online for less than $15 for three o-rings. That’s pretty ridiculous for three o-rings. Thanks for the suggestion though.

since no one here knows the exact size, you'll need calipers and an OEM o-ring(s)
You should be able to find most any size from McMaster-Carr

If you have nothing but time, a gasket company or old fashioned hardware store will match them up.

The gasket company might not be into selling a few, but their minimum order might be both a lifetime supply and still cheaper than a kit.

Thank you. I think that’s exactly what I need to do. Do I just need to measure the overall diameter and also measure the thickness of the ring itself to determine the size?

That’s a great idea. Thank you.

I have a few of those oring assortment kits. In the off chance one of those doesn't work I head to Ace

I will save you the time looking to save $15.
If the Hydrahoe you have has the Paraplate valve in it you will not find a standard oring to fit it.
I had those valves for 30 years. It is made with PROPRIETARY orings.
Manufacturers know exactly what they are doing. They want you to buy their replacement parts and not be able to go to the local hardware store to buy them.
