It's 3/4" pipe, says Orangeburg SP 160psi Water on it. My Dad owned an
underground construction company here for 30 years and said almost all the
services they ran back then for water was this pipe and used brass
compression
fittings, but since new homes have changed, we can't find any fittings.
Which
seems strange because there's thousands upon thousands of homes in the
Phoenix
area that have this pipe installed. The leak is under a 24' wide slab of
driveway and I have no interest in repairing so I found the pipe before it
runs under that concrete and just want to cap it off. Hopefully this
picture
helps.

h. Water Service Pipe: Polyethylene.
1. Orangeburg SP premium polyethylene, PE 3406, class 160, SDR-9
(CTS-OD), rate one hundred sixty (160) psi, with a cell classification
of 345434C as defined in ASTM 3350, manufactured by Orangeburg
Industries, Inc.

Found ASTM 3350 which gives table of dimension systems for given
pressure ratings find

Standard Dimension Ratio Standard Pressure
SDR (In the Case SIDR (In the Case Rating (psig)
of Pipes Made to of Pipes Made to HDS = 800psi
Standard ODs) Standard IDs)
11.0 9.0 160

which tells what the diameter ratios were for 160 psi pipe (culled the
table down simply for the one of interest) and, one presumes, the CTS=OD
spec means they used the OD spec's. Hence, a current manufacturer's
polyethylene fittings for OD-sized pipe _should_ work.

Hadn't know this part on history--Orangeburg Mfg was bought out by
Flintkote some time back in '50s (found ad for the CP pipe archived from
a Life magazine in '59 where were listed as a Flintkote company).
Flintkote was primarily an asbestos roofing and siding, etc.,
manufacturer from 1900 on until after WW II began buying up other
building product companies such as OB. But, they fell prey to the
asbestos hysteria and filed permanent bankruptcy in 2012...all there is
no is the case lawyers fighting over the trust funds left from the
disposal of assets.
