Title: Inner diameter oil lines? Post by: stopintime on September 27, 2012, 10:05:51 AM I'm installing a Pegasus oil thermostat.
To find the correct adapters I need to know the inner diameter of the oil lines. Do you know? [thumbsup] Title: Re: Inner diameter oil lines? Post by: Speeddog on September 27, 2012, 10:35:45 AM I was curious, not knowing for sure.
A search for "oil cooler line size" showed a common answer of -6. But that's not a whole lot better than a rumor.... I'd wager Duck-Stew would know off the top of his head, he's done a number of oil-cooler mods. Title: Re: Inner diameter oil lines? Post by: stopintime on September 27, 2012, 10:47:21 AM What I keep reading is that AN6 adapters are used.
I guess that might be the same thing as a -6 line. The outer diameter is .5" / 12.5 mm, but that's not enough info for Pegasus. Title: Re: Inner diameter oil lines? Post by: Speeddog on September 27, 2012, 11:02:03 AM AN6 defines a thread size and fitting profile, but it's not the end the hose goes onto.
It's the end that threads onto (or into) another fitting or port. -6 is the hose size, and it designates (approximately) the inner diameter of the hose, in 1/16". So -6 hose is approximately 3/8" inner diameter. Title: Re: Inner diameter oil lines? Post by: Duck-Stew on September 27, 2012, 12:42:34 PM All the oil cooler mods I've done used -6 hose & fittings. I never measured but I'd wager the ID of the OE line is really close to -6...

Thanks [thumbsup] |
