engineered elastomeric technologies for sealing, clamping, actuating Retention Systems Corner Details Standard Profiles Type 1 Custom Profiles Inflatables Seals Pneuma-Seal inflatable seals are the perfect solution for difficult sealing conditions. They are particularly well suited for use with: When in action, inflatable clamps provide uniform controlled pressure to firmly clamp pieces together during bonding steps or to hold pieces in place during machining or cutting operations. Typical applications include the bonding of airframe components, clamping during cutting operations, and...

Pneuma-Seal Construction Extruded Construction Molded, Fabric Reinforced Construction Extruded inflatable profiles are typically used as dust seals with little to no pressure differential. Note that the high pressure, low gap Type 10 profiles are an exception to this rule. In applications involving high pressure and/or repeated, continuous use or where safety and reliability are of major importance, a molded fabric-reinforced seal is recommended. The molding process eliminates spliced joints and the fabric reinforcing gives additional structural integrity ensuring better resistance to...

Seal Configurations Inflatable seals can be configured to practically any shape or size. Individual seals can be supplied as continuous loops for axial or radial expansion, in strip form with specially sealed ends, in “U” or similar shapes with preformed corners, or as axially expanding rectangles. preforming or special molding, however, if the corners are tight then molding will most likely be required. Minimum bend diameter data for circular seals and radius corner data for rectangular seals is available on the web by profile (see pawlingep.com/pneuma-seal/standard_profiles). In many...

Applications in Detail Bulk Bag Unloading Seal Airtight Doors Drum Unloading Seal Flexible intermediate bulk bag containers (FIBC) are commonly used in the pharmaceutical and food processing industries to efficiently transfer and store dry powders. These bags are made of a high quality, strong polypropylene fabric. In this process, optimizing the amount of material stored and reducing waste during loading are very important. To ensure a positive seal and account for any tolerance variation, inflatable seals are installed along the periphery of airtight doors and are designed to expand...

Sliding Marine Window Seal Airframe Component Bonding Bladder Large Diameter Seal for Nuclear Power Reactor Cavity Inflatable seals are the perfect choice for sliding window or door applications. In this instance, a sliding window has been designed for the Captain of this Coast Guard vessel. Under normal use, the window slides open so verbal orders may be issued. But when rough seas approach, the Captain can shut the window and inflate the seal to ensure zero leakage into the cabin. Current airframe manufacture involves the use of epoxies and other adhesives to bond the metal skin layers...

These footed style seal profiles are widely used due to their ease of retention and ability to fully round out when inflated. Type 1 profiles may be used in straight, radial or axial expanding applications. Extruded Construction Molded, Fabric Reinforced Construction Recommended Gap: Gap recommendations assume optimal sealing conditions. Depending on the application, the designed gap should be reduced to ensure effective sealing. Contact Pawling EP for further details. Materials: In some cases, a profile can be specially manufactured in other materials, although setup charges may apply....

These profiles are designed primarily for tightly spaced endless radial expansion inward or outward sealing applications where the seal can be snap fit into a retainer groove. Straight and axial configurations are also available although adhesives may be required to keep the seal in place. Extruded Construction Molded, Fabric Reinforced Construction Recommended Gap: Gap recommendations assume optimal sealing conditions. Depending on the application, the designed gap should be reduced to ensure effective sealing. Contact Pawling EP for further details. Materials: In some cases, a profile can...

The footed snap seal delivers relatively large travel for its width so it can close large gaps. The dovetail designed base may also be retained mechanically. These profiles are best suited for expansion axially or radially outward. They are not recommended for inward expansion.

Similar to the Type 3 profiles, these designs cover a large gap for their width and can be easily retained within a square channel. These channel style profiles handle heavy duty lifting and/or gripping applications and can be mounted in standard aluminum retainers.

These heavy duty channel profiles can seal against high differential pressures, but the sealing gap must be relatively small. Axial, radial, and straight seal configurations are common for this series. angled bead Specifications profile standard materials Recommended Gap: Gap recommendations assume optimal sealing conditions.
