Snap-In Inflatable Seal Profiles

Snap-in type inflatable seal profiles utilize a dovetail-designed base that enables the seal to simply "snap" into a matching retainer groove. The retainer groove provides support and protection for the seal. Installation and replacement is quick and easy.

Bond-In Inflatable Seal Profiles

Bond-in type inflatable seal profiles take advantage of an easily machined or fabricated straight-wall groove. This permits the seal to be positioned and bonded into place.

Encapsulated Inflatable Seal Profiles

The encapsulated inflatable seal profile allows for the seal to be "captured" in a groove by securing bar stock over the edges of the groove. The same effect is realized by trapping the seal in a specially formed channel. This approach employs an inflatable tube actuating a solid rubber shoe to the striking surface.

Fasten-In Inflatable Seal Profiles

The fasten-in inflatable seal represents a versatile system that utilizes a variety of metal fasteners such as bars, pins and clips, which can be tack welded or screwed down to the mounting surface.

Recessed Groove Inflatable Seal Profiles

The recessed grooved type inflatable seal, generally used with smaller diameter seals in a radially in or radially out mode, holds the seal in place by its own tension or force. When larger diameters are required, studs can be used.
