Pipe Adapters
Male pipe to Valco external adapters
Male pipe adapters make a minimum volume connection
from the female pipe fittings typically found on pressure
gauges and regulators to Valco external fittings. Standard
material is 300 series stainless.
Note:
We do not manufacture adapters with 1/16" external
fittings because they have very thin, easily distorted walls.
We recommend use of the PZAs on the facing page.

tech tip
Because of their dead
volume and the risk of
thread leaks, pipe fittings
are a poor choice for
trace gas analysis. Thread
sealants, particularly PTFE
tape, cannot boost their
performance to adequate
levels. For trace gas
applications, choose Valco
zero dead volume fittings
with gold-plated stainless
ferrules.
