Home » Your CinchSeal Guide
Welcome, and congratulations on your new 9700 CinchSeal. You’ve made a smart investment in improving processing efficiency and reducing maintenance downtime. This page serves as your central resource for replacement parts, technical support, and quick assistance tailored to your specific seal model. We’re here to support your success every step of the way.
Proper installation is critical to CinchSeal performance. Always follow our installation manual closely to ensure a secure, long-lasting seal. If you have any questions during setup, don’t hesitate to contact our team for guidance.
The shaft and vessel should be totally clean of any wear, dirt, oils, or grease before installing the seal. Make sure that the shaft is perpendicular to the equipment wall on which the seal will be mounted, and the shaft surface finish is higher than Ra125
Place O-ring cord stock in the groove provided on the Split Endplate.
Assemble the Split Endplate around the shaft using the provided hardware specified in the assembly drawing. Ensure the split line is uniform with no raised edges at the split line.
Assemble the inboard PTFE rotor cup around shaft using (2X) MS X 2SMM Truss Head Cap Screws and MS X 20MM Barrel Nuts. Do not overtighten the screws, this could cause damage to the PTFE rotor cups. (Torque value: 4 in-lbs)
Wrap the split boot round the shaft and glue the puzzle cut with RTV. Wipe off any excess RTV frm the joint on the side touhcing the PTFE rotor cups. Allow adequate time for the RTV to set (about 3 hours) befor applying air pressure.
Assemble the outboard PTFE rotor cup on the shaft by repeating the instructions in previous step. Slide it along the shaft such that the boot
fits into counterbores in both the rotor cups. (Torque value: 4 in-lbs)

Replacing CinchSeal internals helps maintain performance, prevent leaks, and avoid equipment damage. Our replacement kits serve as a preventative way to keep your processing most effective For optimal results, contact our engineering team for recommended replacement intervals tailored to your application.
Remove mounting nuts or knobs holding seal and slide cover plate or housing down shaft.
Remove screws in both PTFE Rotor Cups and cut off elastomer boot.
Clean housing from product
Place split boot around shaft between the rotor cups. To achieve a tight, interference fit, there should be a small gap roughly around 1/16” between the 2
halves of the blue elastomer when you wrap it around the shaft. If there is no gap or the gap is larger the shaft size is incorrect and the seal could fail
prematurely. Please re-measure shaft and contact CinchSeal before continuing. A new split elastomer may be needed.
Glue the split puzzle cut with RTV if not
performing weekly or monthly cleaning or inspections. Hold glued joint together for 10 minutes minimum for curing purposes and allow 3 hours for it to dry before
turning on the air purge. (Total curing time is 24 hours))
Push rotor cups and boot together. Boot hubs should fit into bores in rotor cups. The
rotor cups should be orientated with each other, so their split lines are 90 degrees
apart from each other. Slide assembly on shaft until inboard rotor cup seats up against
inner housing bore surface. There should be a slight resistance on the shaft when
moving parts.
Place end plate against housing and fasten to bulkhead.
