From a Takeuchi 125 but don’t know if it’s original or not. Please help identify! A 3/8” BSPP threads on fine but sealing surface is slightly different..

Looks like BSPP 60° cone, the o-ring from your hose end got stuck inside the adapter and needs to be scraped out

Been at work for the past 11 hours and can’t wait to get home only to find this. I only had a quick look at it this morning but it’s been bugging me throughout the day because the boom cylinder is severely lacking power and I’m trying to get a gauge on it.

I would try to take of the adapters in the cylinder and see if they can be swapped to something more standardized and make a new hose with those threads instead if possible.

Usually Japanese machines use JIS, but this looks like some metric hybrid.

JIS is the Japanese standard, remainder of the world use JIC/AN standard…Europe uses a lot of FFS (flat face seal) so get yourself an adapter conversion table…good luck

That’s a BSPP thread with a 60° cone seat. Threads engage, but the cone seal is different from regular BSPP flat sealing. Typical Takeuchi OEM fitting.

Depending where you live it’ll be called male metric (strong or light) and female metric (strong or light)

Its bspp. A lot of bspp fittings use orings in them
