Harold,

I'm pretty sure that it's a straight thread.  But don't have one loose 
to confirm.  If it was tapered, there'd be no need for the sealing 
washer.  Probably a British Standard Parallel Pipe thread.  Not much help.

Cheers,

Question:

Is this an original part--i.e. it came out of this block--or 
aftermarket? If it's a new part maybe try a different vendor.

I'm not crazy about stacking washers to make a nonconforming part work, 
but at least you don't have to look at this every day. But, you now have 
to have to have two washers seal to each other in addition to sealing to 
the block and the 'union.'

I am quite sure the thread into the block is straight, not tapered.  The =
adaptor should screw up hard onto the copper washer.  The thread may be =

Harold,

I agree with Mirek.  I=E2=80=99ve checked both of my spare 3000 blocks, =
and a Wolseley 6/110 block.  All have the =C2=BD=E2=80=9D straight =
union.

That yours is tapered suggests it has perhaps been modified at some =
time.

After the comments I checked the measurement of the fitting. The pitch =
is 28 TPI and the major diameter at the top is 0.402=E2=80=9D and =
0.372=E2=80=9D at the bottom. The measured taper is very close to the =
16:1 for BSPT. These measurements fit very closely to a 1/8=E2=80=9D =
BSPT except the measured major diameter is more than the 0.383=E2=80=9D =
listed for BSPT.

=20

The hole in the block is tapered as well.=20

=20

I will check the threads in the block to see if they are clean and in =
good shape. I am quite sure these are original parts, are there some =
other obsolete British tapered fittings slightly larger than BSPT? =
Whatever size this fitting is it won=E2=80=99t be easily replaced or =
repair and I will be very careful with it.
