Subject: 3/8" BSPP fittings
|
I'd like to descale my Techno. Because I'd rather not snake the input
hose away from its current path behind the dishwasher, I'd like to make
up a new piece of hose with the same fitting on the end of it, along
with a male bit to plug up the existing hose so I can turn the water
back on. The inlet on the Techno is 3/8" BSPP, but it has a silicone
gasket in the female side. In other words, it looks like a garden hose,
except that it's smaller and more precise. The 3/8" BSPP female
fittings my local hose shop has have a hemispherical piece in them that
looks designed to create a compression joint with some sort of flare
fitting, not the gasket I need. Anyone know what the Techno fitting is
called, and where I might find one? I suspect, actually, that I could
get it from McMaster-Carr if I knew what to call it.
Best,
David

Has it been a year already? You're home?
How was the sabbatical?

you might try that anyway, as the hemispherical piece may seal on the
fitting, removing the need for a gasket.
search mcmaster for "bspp" and then look under pipe fittings and tube
fittings, and you might find something that'll work.

Just from personal experience, the hemispherical fitting will not work
without some serious gasket/collet/tape placement and there is still
the propensity to leak when the machine is moved.
Most commercial espresso machines have the 3/8" intake fitting you
describe. Any espresso company should have the intake lines, many
times with braided steel. Lacking a source for that, I have used 3/8"
MIP female (brass) fittings with teflon tape. If you use a pipe dope,
make sure it is not one that hardens....al

I believe the type of water line you are looking at is teflon, and
probably uses a plastic ferrule/ seal along with the fitting.
If you are looking to purchase BSPP fitting, seals or o-rings, go to
www.marylandmetrics.com, they sell every metric thing you could
imagine.
They may even sell BSPP conversion fittings, once applied you can then
use Standard fittings and hoses. No matter how close a Standard
fitting seems to fit, you are eventually going to run the risk of
completely stripping the fitting or blowing a leak, especially on the
pressure side of the system.
I can never understand why so many espresso manufactures use such
obscure British pipe thread (BSPP) fittings in the first place.
Hope that helps
