Advantages of IP67 Gaskets and IP68 Gaskets
Die-cut gaskets for IP67 and IP68 enclosures provide strong environmental resistance, which makes them a good choice for electronics. The first digit in an IP rating describes the level of protection against solid particles. For example, the 6 in IP67 and IP68 indicates that the enclosure is completely dust-tight. The second digit describes the level of protection against water. The 7 in IP67 indicates that the enclosure withstands immersion up to 1 meter. The 8 in IP68 indicates that the enclosure withstands water deeper than 1 m.
Materials for IP67 Gaskets and IP 68 Gaskets
Typically, IP67 gaskets and IP68 gaskets are made of low-durometer silicone rubber, including closed cell materials. Softer silicone grades conform to surface irregularities on plastic and metal enclosures and readily fill small gaps. They also provide cushioning, insulation, and reliable sealing under lower clamp pressures. Marine environments may require IP67 and IP68 gaskets that resist salt water or salt fog, and sunlight (UV) and ozone.
Design Considerations for IP67 Gaskets and IP68 Gaskets
Die-cut gaskets for IP67 and IP68 enclosures require proper seating and good wetting properties to ensure effective sealing. Otherwise, small gaps or under-compressed areas may allow the ingress of water or dust particles. Grooves or adhesive backings, and the use of rigid housing materials are also important to consider. For example, submerged gaskets may require a rigid housing to prevent flexing between enclosure fasteners.
