I wondered if anyone could help me identify some threads, as i need to get a adapter to make existing pipework on my Routemaster fit a new accumulator and i'm struggling with the non metric types


This fitting has been removed from a Clayton type Accumulator.
The Thread on the left (screws into pipework) i believe is a 5/8 JIC - anyone able to confirm? it measures 5/8inch or 15.9mm across

I have no clue what the other thread is (screws into the old clayton type accumulator) , it measures as shown in the photo 3/4inch - 19mm but can't find a chart to match it to. It looks tapered in the photo but it is not.

i need to make the old pipe work fit a female 3/4bspp on the new accumulator

My bus number (if any): RMF2771

Jic fittings are UNF thread form. BSP thread sizes refer to the OD of the pipe. An Hydraulic hose company will identify the fittings for you and supply.

Hi Matt,
Hopefully you may of got this sorted by now but in the past I have used a company called Pirtex for anything to do with pipework and hoses. They supplied my water,turbo and hydraulic hoses last year when I renewed them all on 2463.

My local branch is in Leyton, the guys in there are very helpful and have got me out of trouble many times with things for the bus. I'm not sure where you are based but there should be a branch near you somewhere.


Regards,
Pete.

Hi Peter,

No i haven't stored this out but purely because i haven't had time to pop to the watford pirtek yet, that's my plan for wednesday on my drive home from work!

i found pirtek were great when it came to making a emergency repair for my hydraulic test point (see my previous post about that)to get my bus back on the road with a series of adaptors to fill the gap.

Cheers
