Threaded Adapters
Here are application ideas using two of our popular adapters:
Many injection valves used in HPLC systems have 10-32 coned ports
designed to accept 1/16” OD tubing. However, this may be a problem
if large injection volumes are required (in excess of 10 mL). The most
popular loops for large volume samples are made from 1/8” OD
tubing, making it impossible to connect these larger volume loops
to your injection valve. The solution: use our P-654 Adapter and
the appropriate fttings for your sample loop. This set-up allows
connection of 1/8” OD sample loop leads to your injection valve.
Another potential application is connecting tubing to low-pressure
solenoid valves with 1/4-28 fat-bottom ports. Most low-pressure
valves of this type have very shallow threaded ports, which typically
preclude the use of our Flangeless Fittings. However, by frst threading
our P-671 Adapter into the valve port(s), you can effectively use standard
1/4-28 fttings to connect your tubing into the backside of the adapter
body. This also saves ”wear and tear” on the threads in the valve ports.
Application Note
When using an adapter with male (external) threads, we recommend
you frst attach the adapter body into the receiving port, and then
connect your tubing and ftting into the head of the adapter body.

You may not need an adapter to connect 1/16” OD tubing into your
fat-bottom port. A less expensive alternative is to use a Flangeless Nut
