I'm working on my Yanmar VIO70, and have found the hydraulic line ends look strange, They look like an upsized NPTF swivel type fitting. This is a 1 inch hose diameter. The male end has a straight thread and bevel on the inside.

I wager it's BSPP as well.
It's been awhile but my hose maker was able to get an adapter for me. I don't recall the exact sizes I was dealing with but it was quite a bit smaller than you are dealing with... I do remember it was a pricey little booger though.

Agree. I've changed a plenty of nipple adapters that were BSPP on both ends, like the auxiliary pipe connections on excavator arms. They make adapters that are male BSPP to male JIC, pretty easy to come up with those. But if you're looking to adapt male BSPP nipple to female JIC, I dunno.
Excellent suggestions, I'll check with my local Napa guys to see if they have any BSPP ends but under the floor, I do see some weeping hoses and will be changing out the original 20 year old ones as they show signs of impending failure.
Well, local hose jockey has some BSPP -8 ends, but they're pricey, I suppose I could start changing lines over to JIC. I've never blown a line twice so I'm thinking just eat my veggies and keep the machine all the same, Have my local store keep a few BSPP ends in stock for me.

Having a fleet of Takeuchi and Yanmar equipment, and several other brands with threads/ connections other than the more common JIC, STOR, ORFS, and NPT, I can assure you that Gates, Aeroquip, Parker, and even Caterpillar have BSPP, BSPT, DIN light, and DIN heavy fittings available. Since they lasted 20 years the first time around, why expend the effort for custom?
The only effort I expend to eliminate fitting issues is to get ORFS off of my attachments as these idiots always seem to screw up the oring. In that case, I sub in JIC fittings and hose ends (but not until repeated oring failure).
If you want to pick a common machine with uncommon fittings, try Komatsu. But, even there, the fittings have become almost commonplace.
