Savav2v1 Posted May 28, 2019 Posted May 28, 2019 Evening all Noticed a slight wheep on my kats oil cooler fitting between the earls elbow and rad adaptor..decided to crack it open..wipe..relighted and hey presto..now pisses out..but under the elbow flats..and out of what looks like a small hole again on the nut flats Don’t know what threads these are but it looks like some kind of ptfe tape is used on the rad adaptor so maybe NPT..dunno...anyway any advice how to assemble these fitting would be pukka..thank you very much ....your time is appreciated Quote
Daveyboy Posted May 29, 2019 Posted May 29, 2019 PTFE tape will add to thread diameter and crack unions.prob better off fitting a new union.cup and cone face fit and nipped up gentley.ptfe tape is now an mot failure/illegal on hgv air brake systems because it leads to cracking alloy.im sure thread size is bsp. 1 Quote
Savav2v1 Posted May 29, 2019 Author Posted May 29, 2019 Cheers buh.....I think the adapter on the rad is the wrong type to fit the elbow...hence the ptfe and they both look like there on the piss/cross threaded.. Quote
Gammaboy Posted May 30, 2019 Posted May 30, 2019 Has someone tried to jam AN or JIS fittings onto BSP threads? 1 Quote
370steve Posted May 30, 2019 Posted May 30, 2019 connector looks to be sat at an angle!! not on threads correctly?? Quote

When correct, the taper seats between fitting and rad will seal with little more than finger tightening - PTFE on the threads only used to stop threads galling / welding together over time - NOT SEALING LEAKS Quote
dupersunc Posted May 30, 2019 Posted May 30, 2019 Those fittings shouldn't have ptfe tape anywhere. most likely there is BSP to JIC adaptor in the cooler that needs replacing. cooler BSP, oil line JIC. If you go on the Goodridge website there will be a chart to help you identify sizes. Quote

Dezza Posted June 2, 2019 Posted June 2, 2019 New coolers are not too costly, look on ebays for one the correct size. The cost is mainly in the fittings and Earl's especially so personally I would make sure I know what size Earls fittings they are, then buy a new cooler of the correct fitment. Also the last leak I had came from where the hose meets the fitting, as it had gone hard over time but all that PTFE tape suggests that someone has tried this to seal mismatched hose fittings. Quote
dupersunc Posted June 2, 2019 Posted June 2, 2019 Never ever any need to run ptfe tape on those JIC fittings. Thread form is unf. AN-6 are 19/16" unf AN-8 are 3/4" unf AN-10 are 7/8" unf Quote
dupersunc Posted June 2, 2019 Posted June 2, 2019 Someone has done a neat job of converting it to those fittings, but if the tapered seat is marked they won't seal. looks like you need a new cooler at the very least. Quote

Looks like you need a new cooler at the very least. Looking at the cooler threads - they are goosed and probably, even with the correct threads, it's unlikely they'd tighten down correctly! Just hope the line fittings aren't equally mullered. 1 Quote

Totally agree...no the oil line fittings look as new to me at both ends 8 hours ago, dupersunc said: Never ever any need to run ptfe tape on those JIC fittings. Thread form is unf.
