IP-Rated Sealing Solutions

Higher IP Ratings Begin with Complete Sealing Solutions

Protection against dust, moisture and fluid ingress must be engineered into the overall design and production of electronic enclosures, especially in harsh environments.

Too often, these enclosures suffer from “sealed” parts that don’t hold up in extreme conditions, like outdoor control systems, EV battery enclosures, marine electronics and industrial automation.

That’s where ZAGO comes in—and makes all the difference.

Closing the Fastener Gap in IP Design

For years, ZAGO has engineered sealing solutions that fortify sensitive equipment enclosures and support higher Ingress Protection (IP) performance.

IP ratings apply to the complete enclosure or assembly, not individual parts. Yet achieving these ratings demands integrity at every connection point, since every fastener represents a potential leak path.

How ZAGO Supports Higher IP Performance

ZAGO’s self-sealing fasteners are engineered to help achieve higher IP ratings for enclosures by eliminating common leak paths at the fastener level.

Each ZAGO sealing screw, bolt, washer and nut incorporates a precision-molded rubber O-ring seated in a specially designed groove beneath the head. Once installed, the O-ring compresses into the groove, forming a 360-degree barrier against air, water, oil, dust and other contaminants. This same protection is available in ZAGO’s switch boots and crystal seals, among a variety of other fastener products.

ZAGO’s integrated sealing:

• Blocks moisture, dust and contaminants
• Helps prevent fluid migration through threaded penetrations
• Reduces reliance on secondary sealing elements
• Improves consistency in automated and high-volume assembly

By sealing at the point of potential ingress, ZAGO fasteners help maintain enclosure integrity — a critical factor in passing IP validation testing.

The Limits of Traditional Fasteners

Traditional screws and bolts rely on:

• Secondary washers or gaskets
• Applied sealants
• Thread tapes
• Manual assembly precision

Those added components introduce additional opportunities for wear, compression or misalignment over time, leading to greater ingress, while also increasing part counts and complicating assembly.

In contrast, ZAGO transforms fastening from a simple mechanical function into a critical contributor to overall IP performance.

Engineered for Compliance, Not Assumptions

IP testing evaluates the performance of the entire system under defined exposure conditions. Even a minor leak at a fastener location can compromise test results.

When equipment must withstand washdowns, outdoor exposure, submersion or airborne particulates, fastener-level sealing becomes a meaningful design variable. ZAGO’s integrated sealing solutions reduce potential failure points and support long-term equipment protection—all while simplifying assembly.

Protection Without Compromise

IP ratings are earned through disciplined design and consistent builds.

ZAGO’s team of U.S.-based engineers works alongside customers to support material selection, verify environmental compatibility and ensure the sealing solution aligns with system-level IP goals.

By integrating sealing directly into the fastener, nut or washer, ZAGO helps engineers close one of the most overlooked pathways for ingress and build enclosures that perform as intended.

When every connection counts, ZAGO delivers.
