Default 1972 Oil Pressure NPT Fitting

Hi guys,

On the '72 LT-1 we're fixing, the oil pressure pipe broke off just above the NPT fitting in the block.
Is it possible to just replace the conical bit that screws into the adapter in the block? If so, can someone please help me find fittings like that?

Your help is much appreciated!

Cheers

Es

I believe the only way to buy it is in a kit or check your local hardware store because you never know.

Thanks guys!

@ Derek: there isn't much to see - looks just like in the corvettecentral pic 67:72 posted. What we need is a conical brass "thingy" and possibly the hollow "nail".

These things are sure some kind of standard pressure fitting, no?

Cheers

Replacement lines come with the correct conical fittings.

Replace it, end to end. Plastic gets brittle with time.

i believe that is a 1/8th compression fitting. i also believe the rest of the line is just as old and brittle as the part that broke. and should be replaced before you pump oil into your carpet. but if doing top flight and must have OE line... https://www.summitracing.com/parts/edd-111200 post 7 and 9. https://www.corvetteforum.com/forums...ting-size.html

The two metal fitting pieces need to be from the same manufacturer so the connection will work properly. I think that line is 1/8", so you need a compression fitting for 1/8" tubing and a pipe fitting to adapt it to the block (1/8" NPTF, I believe).

You can purchase the whole kit...but you only need to compression fitting and the pipe adapter.
