Hydraulic jack ram oil seal, where to buy?

[robbocop33]

Bog standard floor trolley jack, a Halfords yellow jobbie, you know the type. It's not holding pressure and the seal is seeping. I've taken it apart and the seal is a square profile oil seal. Any idea where i can but one, can't see any of this type on Ebay?Inner Diameter is about the same as a 10p piece
Here's a pic or two

Bath tap washer and drill it out to the correct size?

Last resort maybe...

Have you contacted the manufacturer/vendor?
Looks like a clutch cylinder washer, measure the bore and get a repair kit for one of those.

Take it into a local bearing & seal stockist (yellow pages, google search etc) & see what they've got.

All such oil seals are standard items. You need to measure the rod it fits on plus the bore it fits into accurately and then ask any oil seal supplier.

Or hydraulic specialist/hydraulic hose repair place.

Don't know if it's the same size but I bought one of these from this site for a 30 yr old Master Mechanic jack. This was for the part that the handle actuates to pump it up.

Have a look around the site. They may have one like yours.

Measure it up the cylinder and ram diameters and seal thickness and buy the correct size.
