NOWPAK LINER-BASED CANISTER SYSTEM
User Manual | Entegris, Inc.
One-Piece Closure
The 63 mm neck thread canister type can use the
one-piece closure, Figure 9, and then only when an
ND-LD dispense connector is used. The 63 mm neck
thread canister type allows the one-piece closure to be
installed directly onto the canister.
At the end user’s site, the one-piece closure is
removed, and the ND-LD dispense connector is
installed directly onto the canister neck. No breakseal
is used in this arrangement. See ND-LD Dispense
Connectors page 9.
NOTE: The 63 mm neck thread canister type can also use
an NC-04 two-piece closure when an ND-CD dispense
connector is used.

CHEMICAL DISPENSE CONNECTORS
Three different types of chemical dispense connectors
are available to meet specific dispense conditions.
Refer to the NOWPak liner-based canister system data
sheet or contact Entegris for application-specific
information, options, and model numbers:
• ND-CD
• ND-LD
• ND-ED (MaxMT
™
system)
Refer to the relevant Entegris user guide or data sheet
for specifications and for detailed user and maintenance
instructions for each type of dispense connector.
ND-CD Dispense Connectors
The ND-CD series pressure dispense connector,
Figure 10, provides a clean, convenient, and completely
sealed method for dispensing chemicals from
liner-based canister system containers. ND-CD
dispense connectors have all fluoropolymer wetted
surfaces and require the use of a two-piece closure.
(When installed on a canister, the dispense connector
threads onto the closure base.)
ND-CD dispense connectors can be used with any
size canister (4- to 200-liters), however, some ND-CD
models have longer threaded collars, and other
models have shorter threaded collars. Collar length
affects which dispense connectors are accepted by
each canister. See Appendix B: Canister Compatibility
Matrix, page 32, for information on matching ND-CD
dispense connectors with appropriate canisters
and components.
See the
ND-CD Connector Series Operating and
Maintenance Procedures Guide
for detailed user
information on these dispense connectors.
ND-CD-SA Type (Slotted)
Slot in the upper connector body
for the tubing to pass through.
ND-CD-SB Type (Strain Relief)
Holes in the upper connector body
for the tubing to pass through. These
holes prevent the fitting from being
turned by the tubing.
