Bud Industries
Waterproof enclosures provide a dry internal environment for printed circuit boards and electrical components, protecting designs from rain, snow, and factory washdowns.
Bud has a large inventory of many sizes and styles of waterproof / weatherproof electrical enclosures made from plastic, die-cast aluminum, extruded aluminum, fiberglass, steel, and stainless steel. All carry NEMA ratings or IP ratings that indicate the exact degree of protection, whether it’s protection from a light sprinkle of water to complete submersion. These ratings include NEMA 4, NEMA 4x, NEMA 6, NEMA 6P, NEMA 12, and NEMA 13, IP56, IP56, IP5, IP66, IP67, and IP68.
Browse our offering of waterproof electrical enclosures below. Remember to add waterproof accessories like cable glands to maintain the waterproof seal.
After you make your selection, let us make your custom cutouts. Most of our NEMA and IP enclosures qualify for our industry-leading modifications program, which gives you cutouts in as few as five days.
The key to making an enclosure waterproof is a tight seal. For electrical enclosures having the highest level of water ingress protection, this is usually accomplished using a continuously poured silicone gasket and a tight-fitting cover. In other enclosures, water-tight gaskets may be made of other materials. Covers are secured with screws or with strong latches. Any possible gaps, such as in steel or stainless steel, enclosures must be fully sealed, usually by a seam weld. No gaps can exist.
There are many styles of waterproof electrical enclosures. Although our line is one of the largest in the industry, it may be helpful to see a few examples.
The list is seemingly endless. Browse our selection to find the perfect fit for your application.
How waterproof do you need? NEMA ratings and IP ratings define specific levels of protection against dust and water ingress. Our line includes weatherproof electrical enclosure protection all way up to NEMA 6P and IP68, which protects your design even when temporarily submerged in water.
Where will the enclosure be used? Plastic enclosures must be UV rated for outdoor applications. Indoor applications that will be washed down with hose-directed water require at least a NEMA 4X or IP65 rating.
How will the enclosure be used? Considerations include how often the user will need access to the components inside the enclosure. A hinged enclosure will make access fast and convenient yet still completely secure.
Are there indicators or displays? A clear cover will allow users to see them without breaking the seal and exposing the enclosure contents to the elements.
Are appearances important? Metal enclosures are available with attractive finishes or with plain aluminum for a low-cost option.
Will the enclosure experience changes in air pressure? Changing weather can sometimes cause condensation to form internally or other issues. Bud offers an IP-rated vent that allows air to pass but blocks moisture. These and other vent accessories also allow heat to escape, meaning there is a weatherproof electrical enclosure solution for most environments.
Will you need to mount the enclosure? Most styles come with external mounting brackets, a few have mounting holes in the back, and some are designed for DIN-rail mounting.
