Kubota B21 backhoe
I am looking for a set of hoses for a kubota B21 with BT751 backhoe, and see a lot of JCB hoses online. It says 3/8 500mm, and i wonder if that would fit on the kubota?

Probably better to determine quick/threaded connections type and have hoses custom made at local shop than to guess with a online hose....

Most NAPA stores can make up hyd hoses. Take off needed hoses, put a tag on it so you know where it goes. Have the hose made and then put the tag from the old hose on the new one.

You can do that but it will cost more than buying hoses on line. You do need to know what to order when you buy online but that's not that difficult.

There's nothing special about Kubota hoses that can't be easily replicated elsewhere.

The hose diameter is usually printed on the hose, along with the bursting strength. You can order the same. Then it's just the hose ends that you need to worry about. And they're likely either NPT or JIC. For each hose size there's one or two common end sizes which you can determine by measuring or sometimes there's markings on the fittings that tell you.

I'll throw this out there since this is for a backhoe, tie a good heavy masons string to the hose before you pull it out so the string follows it, then you can pull the new hose back in with the string. Also if you can do them one at a time, less chance of confusion, ask me how I know...LOL

I have ordered a lot of hoses from DiscountHydraulicHose.com - never a problem with them. They have a "ID a Fitting Guide" that is very good.


And using there custom hose ordering tool makes it easy.

Get out your hydraulic ID guide and a caliper or find a local place you can bring each hose into.

Be sure to blow air through the new hoses to get all small hose bits from the cutoff saw removed. Be sure to have the ends capped to keep them clean while installing.

I have spent thousands with surplus center with no issues.

Replaced all FEL hoses on a B20 from Surplus Center. Much better than the OEM hoses.

Hoses can be made in many configurations of end's and exact lengths. I'd say buying a "set" of JCB hoses and thinking they are gonna work on a B21 kubota has a zero chance of working.

Take hoses to a local shop and have made exact, or identify the size and type of ends, measure the length, and use any one of a dozen online sources

The only drawback to Surplus Center is their pre-made hoses are mostly in 1-foot increments. If you can get by with a 36" in place of a 30", or similar length differences, the hoses are high quality at good prices.

I use DiscountHydraulicHose for hoses by the inch. They're a little more expensive than SurplusCenter's hoses by the 6" (for short lengths) or 1' increment.

Tying a string to the BH hose you're replacing is a good idea.
