Very High Pressure (VHP) fttings, designed to withstand
extreme pressures. This patent-pending line of ground-breaking
ftting systems is perfect for use within the increasingly demanding
requirements of today’s high performance analytical systems.
The Reusable VHP fttings can be reusedwhen following the tightening
torque specifcation listed below. With a polymer front ferrule, there
is no damage to the tubing or receiving port, also increasing the life
of these components.

Application Note
Reusability
Using a reusable ftting eliminates the problems described on stainless
steel ftting interchangeability on page 196 of the Technical Resources
section. A reusable ftting will allow for quick column, sample loop,
inline flter or tubing changes with minimal downtime.
The VHP-300, VHP-305 and VHP-310 fttings can be used up to 30,000 psi
(2,070 bar) if tightened to 14 in-lbs (1.6 N
·
m). This limits the reusability
to 5 cycles. The stacked design of these fttings allows the user to lightly
assemble the ftting before tightening into the port. Leaving the tubing
extended at least half an inch beyond the end of the ferrule will ensure
that the tubing is bottomed out in the port before the ftting is tightened
down, avoiding any potential dead volume that could be introduced
during ftting installation.
Note
The pressure rating provided is an indication of the capability of the ftting,
not the tubing; you should always confrm that your fow path tubing is
capable of your system pressures to ensure operator safety.
Find tightening tools on page 8 designed to deliver the torque necessary
for these fttings.
