Cartridge Assemblies

1. Follow
Pressure Relief Procedure
, page 21.
2. Use a wrench to remove the cartridge assemblies
(2) from the manifold.
3. Use a 90° Allen wrench to pop the seat (2e) and
seal (2f) out of the housing, or tap them out from the
“A” and “B” inlet side.
Seat retainer seal (2f) normally splits into two pieces
when it is fully torqued into the housing. The lip is meant
to retain the seat, spring, and ball during assembly. The
seat retainer seal (2f) must always be replaced once it is
disassembled.
4. Use a soft bristle brush to clean the manifold
passageways.
5. Remove the seat (2e), ball (2d), spring (2c), and
o-ring (2b) from housing (2a).
6. Inspect parts for damage and replace as necessary.
7. Assemble parts in reverse order from steps above.
Press the assembly against a flat clean surface until
seal (2f) snaps into place on the end of housing
(2a). The seal (2f) will hold the spring (2c), ball (2d),
seat (2e), and o-ring (2b) in place during assembly.
8. Apply lubricant to o-ring (2b) and end seal (2f).
9. Apply anaerobic sealant to external threads of
cartridge.
10. Install cartridge assemblies in manifold and torque
to 125 ft-lbs (170 N•m).
The high torque crushes the seal (2f) for a reliable seal
up to 7250 psi (50 MPa, 500 bar).
NOTICE
Be sure to label all fluid parts “resin” or hardener”
when disassembling them. Doing so prevents
interchanging resin and hardener parts during
reassembly and prevents contamination of the
materials and fluid path through the equipment.
Color-coded chemically resistant tape may be used
to label the parts. Use blue for resin and green for
hardener.
