Anyone know the standard o-rings sizes or part numbers for the ISO 5675 ag-type connectors?

My google-fu is weak and I'd like to order some spares.

Thanks,

The ISO 5675 hydraulics commonly called Pioneer connections, do come in 1/4" and 1/2" and 3/4" sizes. A majority of tractors typically use the 1/2" size, but SOME 25Hp and under do use 1/4" and many over 115Hp tractors use 3/4" connections.

So I would confirm your size of Pioneer Hydraulic connections and then check online at following hydraulic super store site:

Mine are 1/2" They are on the FEL valve body for L4330.

Neither HD nor Discount Hydraulics show any o-rings for 5675 type connectors. I e-mailed DH and asked them, no beuno.

And the tech specs, according to Grainger.com is: https://www.grainger.com/product/GR...HB7?searchQuery=50001-211-0260&searchBar=true

If the Grainger specs are true, then it's SAE standard AS568 dash #211. The McMaster part number is 9452K31. It's also part number 211 in this kit from Amazon: QLOUNI 826 Piece Universal O-Ring Kits Assortment SAE + Metric Rubber NBR O-Ring Gasket Set for Plumbing, Automotive and Faucet Repair + 4 Piece O-Ring and Seal Remover - - Amazon.com

MSC version: https://www.mscdirect.com/product/details/96986831

Note that the Grainger version is polyurethane, the amazon and McMaster versions are Buna-N and the MSC is Nitrile. Parker specifies Nitrile for this o-ring.
