Trojan Sealing Gaskets

Trojan gaskets are state-of-the-art in near zero leakage static sealing. The elastomer sealing element is encapsulated in the electrically isolated retainer. The encapsulation of the sealing element permits only microexposure of the seal to hostile environments of fire, chemicals and corrosive fluids.

The controlled confinement of the elastomer sealing ring within the retainer allows for the availability of a 92% to 94% volume filled groove. A consistent controlled pressure seal can always be obtained without tremendous bolt loads. Reduced loads allow for reduced flange thickness with smaller circles and smaller bolt holes.

The cross section of APS’ Trojan Sealing Gasket shows the elastomer sealing element as it appears before compression between flanges. This compression causes the seal to effectively fill the void of the groove and encapsulate, permitting only micro exposure of the actual seal to hostile elements either from within or without.

Duplex Seal Trojan

The Duplex Seal Trojan uses four sealing elements to strengthen the integrity of an already proven gasket design. In critical applications where zero leakage is essential, the dual-seal configuration provides an added layer of protection. If flange faces are slightly out of tolerance or there is a variation in ID dimensions, the secondary seal can compensate. Even when one sealing element is not fully compressed, the other can maintain a complete seal. With four seals working together, the Duplex Seal Trojan delivers reliable performance in the most demanding environments.

Trojan Water Meter

Trojan G-10 cathodic water meter isolating gaskets are NSF-61 approved and state of the art in near zero leakage static sealing for use in preventing galvanic reaction from the use of dissimilar metals on water piping such as steel or cast iron to brass. The elastomer sealing element is encapsulated in the electrically isolating retainer. The encapsulation of the sealing element permits only microexposure of the seal to potable water flow. G-10 Gasket Kits are designed to keep any and all electrical currents from running back to the water meter.
