Good Set of ORFS O-Rings
A handy set of o-rings to have when working on any hydraulic equipment with ORFS fittings. The o-rings are the correct size and well made with no flash at the mold parting line. They work just like they should.

As advertised O-rings kit fast shipping
So this kit comes with everything advertised. the O-rings are of good quality and so far with the one I've used I haven't had any problems. The seller did a great job of shipping it quickly as well. Everything with this buying experience was good. I would recomend this kit and this seller.

Fit just like Parker seals
Worked great on some flat face fittings for skidsteer. Overnight shipping saved the weekend! Old seal blew at 6pm on a Friday..amazon had them to my door 7:45am Saturday. Thanks!

I purchased the wrong kit!
I don't know what the problem is, but these O-rings seem way too skinny. They don't seal. Probably my fault. Yep. My fault. These are ORS/ORFS rings. I needed ORB.
