Scott Health & Safety's SureSeal System is a facepiece seal available for respiratory protection products users. Developed with numerous innovations such as an enhanced sealing surface and practical personal protective equipment (PPE) interfaces, the Scott SureSeal system combines the preference for greater user comfort with the need for superior fit. And because it is integrated with the Scott AV-3000 facepiece, users experience an expansive field of vision and exceptional voice intelligibility. The SureSeal System utilizes a U-shaped seal that maintains a continuous circumferential seal around the user's face. This patent-pending Scott-developed design, called reverse reflex, allows the SureSeal System to flex with every movement of the facepiece, resulting in a higher fit factor and a more comfortable seal for the user. Additionally, a fifth strap improves sealing capabilities by adding another point of connection to the smaller Kevlar head harness. The tightening buckles are thoughtfully placed so they won't torque the seal and cause leaks if over-tightened. A primary feature of the SureSeal System includes a deeper, lower-profile seal that offers a more robust interface with protective suits, hoods, shrouds and helmets. Additionally, a smaller Kevlar head harness eliminates bunching and discomfort under helmets and hard hats. A fifth strap is strategically positioned so that it won't interfere with the head suspension of protective helmets. For proper and quick donning, a reflective positioning tab is located on the back of the head harness. The SureSeal System is available on all new AV-3000 facepieces and can be retrofitted to AV-3000 facepieces currently in use.
