HWH solenoid o'ring size for 310 or 325
I have a 01 DSDP. Solenoid valve is leaking right where it screws into the valve block and the rear jack is leaking down. Yes I have a manual and it is pretty clear where it is leaking. Need to replace the solenoid o'ring that seals the solenoid to the valve body.
Does any body here know what size the o'rings for the HWH 310 solenoids use? 310's and 325's use the same kit. Looks like there are 3? 2 external and one internal? R7430 Kit is way over priced at $25 incl ship for 8 o'rings. Normally pay 5 cents for each o'ring if I know the size. For some reason the sizes are being withheld and HWH does not want to give them up.
Some one out there must have already has to replace them and knows the sizes.
thanks for any help.

Old threads on this subject talked about tKing the 0 rings to the hardware and matching them up.
Some ordered by the bag from Amazon.
The material the 0 rings are made of make a difference for some replacing them.

Auto parts stores usually have many sizes that you could remove your old ones without damaging and take them to the store for a match.

I don’t know the correct size but this might be a solution for you if you have a harbor freight tool store close by.

I have 3 boxs of assorted orings that occasionally I get lucky and can get a fit out of. there are 475 different sizes of orings. Most kits have only 15 or so of these. They are made in a dozen different materials. the type of oring I need is a buna-n. Then there are the metric sizes...... I was just hoping that some one knew what size they were. I've searched to forums with no success.

Never heard from azpete so....
Hydraulic jacks and it is still dropping in the drivers rear due to leaky valve. Decided to pull valve and see what kind of o-rings. Found scratches on the valve that makes me suspect it was removed before. Noticed as I was removing it that the t-valve was loose which may have caused the leak down problem. Tvalve was not leaking, oring at threaded solenoid entrance was leaking due to earlier damage. Pulled valve and found 2 square cut orings around the base that were both damaged. Found 2 square cut orings on the tip with a regular oring between them. One of the square cut rings on the tip was damaged. Suspect the round oring on the tip is not original. New oring kit is $25. So decided to try to fit new ones from my AC kit. Used petroleum jelly as a prelube for the orings.
Original square cut dimensions for base orings:
Mounted overall =.795 actual…. all measurements in inchs
Side to side thickness: .045
Outside to inside thickness: .05
ID: .710
OD: .800 (estimated without damage)
I replaced the base orings with green HNBR AC orings, size: A015
which measure: 9/16 x 11/16 x 1/16 inches .063 thick. I found that the green AC orings were slightly thinner than the BUNA orings but had higher ratings.
Mounted overall, new: .815 on base
Tip round oring: 015 BUNA (black) mounted overall .815
I didn’t bother measuring the flat orings on the tip and I didn’t replace them. I left them in place and installed a new round oring. I used a A015 green AC . new measurement same as old one .815 inches. Guessing that the valve was leaking so some just added the BUNA oring to slow or stop it. I think it would be good to pull the 2 flat ones and just have 2 round ones should I choose rebuild the rest of the solenoids. There may be more orings inside the solenoid but I didn’t bother to open it and replace them. Testing so far: no leaks from around solenoid and no jack drop.

I sent all four solenoids in to HWH for rebuild - got them back in a couple weeks and the cost was less than one new solenoid would be. Call their CS if you want to send yours back.

72 hours, no leak and leak down on the jack piston. so, looks like the round o'rings will work just as well as the $27 square cut kit. I would use the green AC o'rings as they will handle more chemicals at a higher temp. Since I took them out of my AC kit, estimate cost at about .15 cents for the 3 of them.... The thing about the regular buna o'rings is that they don't handle as wide of chemical range.....
Green HNBR AC o'rings, size: A015 are the correct o'rings to do the job...

lonfu, sorry if i didnt reply. ive had the flu for over a week and a half, and cant seem to shake it.
i had to work the fmca rally in perry ga. the same time. never again.
what you did will work just fine. ive use the green orings when i didnt have the ones from hwh. leaving the square ones in place is the right thing to do. they are just spacers. they dont seal anything. great to see someone with ingenuity,

Sorry to hear about your flu bug. I had it and it lasted through Nov. and Dec., then came down again just last week. whew.... gotta be old age... "work".... I've heard of that stuff before but forgotten what it is...
thanks for getting back to me. I was pretty sure I had it right. what do you think about using a couple of o'rings on the tip if the square cut ones are toasted? This was the only thing I was wondering about.
