Retention Systems

For some standard profiles within our Pneuma-Seal and Q brands, retention systems are available. For each system (other than the clips), we offer standard lengths and, for an additional change, can custom cut, slot, or drill. Contact us today to learn more about our capabilities. Detail drawings are available by inflatable profile within the Pneuma-Seal Standards section in the Retainer tab (sign-in required).


Z-Clips for Type 1 ProfilesZ-Clips for Type 1 Inflatable Profiles
This retention system provides for the most flexibility, but requires more work to install. Clips are typically installed on alternating sides of the seal at defined intervals (see below). Intervals can be adjusted depending on seal configuration. In many instances, for rectangular seals, Z-clips are used to hold the corners down while a Two-Piece retainer is used to hold the straight sections.

Two-Piece Retainer for Type 1 Inflatable ProfilesTwo-Piece Aluminum Retainer for Type 1 Inflatable Profiles
The two-piece retention system may be used for the straight sections of an inflatable seal or clamp. One side is typically permanently welded or screwed in place; the other moveable to facilitate seal installation. When specifiying this retention system, please note that you will need double the retainer footage to cover both sides of the seal. For example, a 4 foot section would require 8 feet of retainer - 4 feet for each side.

Slide-In Retainer for Type 1 Inflatable ProfilesSlide-In Aluminum Retainer for Type 1 Inflatable Profiles
Slide-In retainers are typically used for straight inflatable clamps and actuators, because the part needs to be fed into the retainer from one end. They may also be used for u-shaped configurations.

They Type 10 profile designs in particular rely on a properly designed channel in order to function properly. All available channel dimensions may be found in the Pneuma-Seal Profile Standards section in the Retainers tab.
