LA535 loader quick coupler O-ring size

[goon6ster]

I got a Kubota LX2610 with a LA535 loader. The 1/4 inch Parker 60 series female quick coupler is leaking, and I'm pretty sure it's just a worn-out O-ring. I've done some digging and it looks like the dimensions are 11/16" x 9/16" x 1/16", but I'm having a hard time confirming the actual O-ring dimensions for these specific couplers online. Most hydraulic sites just list part numbers without the specs. Has anyone here had to replace this O-ring before, and can confirm those dimensions or point me to a reliable source? Just want to make sure I get the right one before I tear it down. Thanks for any help!

I had a similar leak on my LX2610, and it turned out to be that exact O-ring. It's a -015 size, measuring 11/16" in outer diameter, 9/16" in inner diameter, and 1/16" thick. I picked up a Viton one from a store near me, and it's been holding up good ever since. You should check about this before diving in, those parts listings can be pretty unclear

yeah, your dimensions sound right. For the Parker 60 series 1/4" female quick coupler, the standard O-ring is a dash number 015, which has an inner diameter of 9/16" and a cross-section of 1/16".
So your measurements are correct. You can find these at any good hydraulic supply store, or even on a big industrial supply website. Grab a couple of extras while you're at it, just in case.

Thanks for the heads-up! My brother LX2610 and he spotted a small leak near the loader coupler last week. That -015 Viton O-ring sounds like a good fix, did you notice if it was metric or SAE for sure? Also, did you need any special tools to swap it out, or was it a simple pull-and-replace?

Avoid those generic O-rings from the hardware store. They probably can't handle the pressure or chemicals in your hydraulic system.
