Techseal - Multipurpose Seals and Gaskets
Soft Gasket Material Technology.
Unique blends of cork and select rubbers produce materials indicated for soft gaskets sealing, that due to reduced side flow, allow for larger contact areas and higher compression ratios which guarantee an effective sealing barrier against potential flange surface imperfections, distortions and leakage paths.
In stamped steel or lightweight assemblies Accoseal sponge grade materials are especially useful, being able to compress with minor fastener loading and minimum hardware distortion allowing for an overall optimized system design. Its controlled side flow allows for groove assembling without the need for allowance on the contrary to its incompressible counterparts such as rubber.
Accoseal® products have extensive characterization against automotive application mediums such as fuel, lubricants and coolants. Dedicated grades are UL listed such as NC710, NC711 and NC711G under the UL157 category for fuel. Especially our Epichlorihydrin grade NC711G has been extensively tested in biodiesel and bioethanol fuel blends to various concentrations with remarkable results.
