  • Smart Sensors Manage Resources And Risks With Intelligence
    Recently, Flanders, the northern region of Belgium launched a "smart" water management system based on networked, interconnected sensors. The sensors provide insight into its regions water use, water quality and available water quantity. This is just one of the many ways that intelligent sensors are improving our use of both natural and mechanical resources. But sensors are sensitive! They contain microcontrollers and electronics that can be easily damaged by the infiltration of water, dust and other contaminants.... [...]

The When, Why, What and Who:
A Comparison and Contrast of Our Various Products

Each of our products plays a clear cut role in arming and protecting your mission-critical equipment. Each product is unique, and is built such that it meets very specific requirements. Below, we have drawn up a quick compare and contrast explanation and chart to make sure our products are crystal clear to equipment users and producers across the spectrum.

The Crux of Each Product That We Produce

Self-Sealing Screws

Sealing Screws

Sealing screws are unique screws manufactured specially by ZaGO that have a built-in “O” ring. This powerful “O” ring creates an effective seal around the screw, so that no contaminants can seep into a device, and so that no substances can leak out past the screws. ZaGO produces a number of different types of self-sealing screws, including: Self-Sealing Machine Screws, Self-Sealing Socket Caps & Hex Bolts, Self-Sealing Tamper-Proof Screws, Seal Rivets/Plugs, and Special Seal Screws. The type of equipment you have dictates the kind of self sealing screw that you will need.

Self-sealing screws are utilized by leaders in a number of industries. Professionals who need highly durable and leak-proof fasteners turn to ZaGO every day. For instance, those who use or build fuel tanks would need to use ZaGO’s products to ensure that nothing leaks out of their tanks. Manufacturers of electronic products would need to use our sealing screws to ensure that no dirt or contamination leaks into their devices and damages them. Applications for our self-sealing screws are endless, since all professionals seeking to seal-in substances or seal-out contaminants would need to use our products.

Seal Nuts

Self Sealing Nuts

Our Self seal nuts, much like sealing screws, create a total seal in the otherwise most vulnerable parts of machines, tanks, equipment and so on. Our seal nuts too have a built-in “O” ring devices that gives the seal nut the 360 degree sealing protection it needs to perform under a variety of circumstances. ZaGO manufactures four kinds of seal nuts: High Acorn Nuts, Low Acorn Nuts, Heavy Hex Seal Nuts and Hex Flange Nuts. We can customize seal nuts for you so that they fit your exact specifications.

Self-sealing nuts are critically important in number of circumstances. ZaGO’s sealing nuts replace ordinary nuts in machines and equipment that are exposed to damaging elements such as pressure, oil, water and more. Some of our customers use our ultra high grade sealing nuts to secure hydraulic and fuel systems, while others uses them for instruments in the medical field that are exposed to pressure or bacteria and viruses. In all cases, the idea it of fully protect equipment against leaks in or leaks out due to pressure and/or exposure to contamination.

Switch Boots

Switch Seals

Switch boots, unlike sealing screws and nuts, are designed only to seal things out. Specifically, switch boots are used to protect electronics switches of every kind–push buttons, toggles, rotary switches and so on. Switches are highly sensitive electronic parts that are vulnerable in the face of moisture, dirt, oxidation and contamination of any kind. If damaging particles get into a switch, then an entire device or machine can go down. That’s why it’s so crucial to protect switches with covers that seal out any damaging substances and protect against vibration or pressure. With our products, switches remain clean and functioning optimally. ZaGO offers you a number of switch boots including: Toggle, Push Button & Rotary, Sealing Washers, Multi Switch Panel Covers, Circuit Breaker Cover & Boots and Rocker Switch Boots.

If you have an electronic switch that’s exposed to the elements, then you must keep it defended with a ZaGO switch boot. Whether you have a panel of electronic switches in your boat that need protecting from salt water, wind and bacteria, or whether you have switches on petroleum equipment that need protecting from oil intrusion, we have the solutions. ZaGO’s ultra durable rubber switch boots will fortify your equipment dramatically, and ensure optimal performance for years.

Crystal Seals

Crystal Switch Seals

Our crystal switch seals, much like our boots, act as shields against external contamination. Unlike the switch boots, crystal seals are crystal clear in color to allow you optimal visibility. That’s why they are so great for covering multi switch panels. Wherever switches are supposed to harsh environments, (in most cases outdoor environments) they need air and dust-tight covers. Only ZaGo’s products grant switches such a high degree of protection against contamination. ZaGO produces the following types of crystal seals: Tactile & Dip Switch Seals, Circuit Breaker Seals, Rocker Switch Seals, Full Panel Seals, and Special Rubber Products.

Crystal seals have a variety of applications. Wherever oil, acid, radiation or oxidation threaten the integrity of your switches, you need crystal seals. Producers of military and aerospace equipment, for example, need to keep switches defended in harsh environments, and, likewise, leaders in construction, marine and boating equipment production and many other fields, who need optimal switch functioning in the face of saltwater, dust, and more, count on ZaGO everyday.

The Ultimate Shields Against Leaks–on Sea, Land, Sky or Space

All of our products are designed and built to fortify machinery and electronic equipment against oil, water, pressure, contamination, oxidation, radiation, chemicals and more. Machines that necessitate screws, nuts and bolts should be constructed using ZaGO’s sealing screws, sealing bolts and sealing nuts. Electronic equipment in which switches are exposed to the outdoors must be fortified with our switch boots and crystal seals.

Only by using ZaGO’s ultra high grade sealing products will you be able to ensure that your equipment functions properly. Otherwise, without our products, you will find that your equipment will degrade very quickly. Indeed, ordinary fasteners (screws, nuts and bolts) will allow leakage, and uncovered switches will quickly degrade and disrupt proper machines functioning. The results can be catastrophic. Indeed, all too often we hear of petroleum tanks leaking out toxic substances, or motor boat failure due to saltwater intrusion via switches. There is only one way to prevent these problems: fortifying your equipment with ZaGO’s switch boots, crystal seals, sealing boots and sealing nuts.

Don’t wait for issues to arise. Whether you have a pizza business and need to ensure that your oven’s switches are resistant to oil contamination, or whether you manufacture tanks and need vibration and pressure resistant fasteners–call on ZaGO. We will customize our products to fit your exact specifications. Together, we can solve any sealing problem, and and ensure the safety, longevity, and performance of your mission-critical equipment.
