The Place

Ok got my nice new oil cooler beautifully mounted. Ordered new fittings ready to connect. Said fittings arrive and guess what....they don't fit! Too small!!

Was told the fittings are 1/2" BSP but the fittings I ordered are too small. I.e they wont screw on. Anyone know what the next bigger size is?

TIA

Tripps measure across one of the holes in the cooler. 1/2 inch BSP or NPTF is about 3/4 inch across. Come back with your measurment.

Ian it is 22.8mm (or thereabouts) so i guess a 5/8 BSP is the size?

Tripps, if the 1/2 fittings you have bottom out, wobble a bit the chances are the oil cooler could have metric threads.
If you have a hydraulic hose/fitting supplier by you take it along to them & they will identify the threads for you

It looks like the threads are 5/8" BSP, the o/d of 5/8" is .902" which is 22.91mm.
check the pitch to make sure, it should be 0.0714" ie. 14 TPI.

I'd be very surprised if the threads are 5/8,
5/8 BSP is is not the norm in industry, I may be wrong but tripps say's it is a new cooler so as I say, I'd be very surprised.

I have just ordered a pair of 5/8" fittings so will know for sure by the end of the week. As you say not the norm but has anything involving our oufit been the norm?

5/8" bsp never heard such a load of rot could be 3/4 bsp or one of those silly hydraulic or american threads ian was on about

Errols back

Well the 5/8" fittings turned up and....................they fit! Thanks all

Well, I'm man enough to say I was wrong, in my defence, I didn't see the oil cooler
being nosey tripps, where did you get the cooler from & what is it off, if anything? 5/8 BSP is very uncommon, Goodridge do sell the odd fitting though. Get them temperature strips put on, if you need any more let me know.

Hi Ian, Came from e-bay from a guy in Leicester. Looks to be brand new and un used. Will be fitting the temp strips don't worry. And a pressure gauge too!
