ZAGO: High-Tech Self-Sealing Fasteners Protect & Preserve Your Most Sensitive Equipment
ZAGO manufactures U.S.A.-made, high-tech, sustainable sealing fasteners (sealing screws, sealing bolts, sealing nuts, sealing washers) for thousands of engineers, OEMs and distributors worldwide.

The Difference:
Unlike ordinary fasteners, ZAGO sealing fasteners are uniquely engineered with a groove under the head of the fastener or the face of the nut that when combined with a rubber O-ring and tightened, creates a 360-degree air-tight seal. This impervious, unbreakable seal prevents dirt, moisture, disinfectants, oil, gas and other contaminants from entering and damaging high-asset equipment and hazardous substances from leaking into the environment. ZAGO sealing fasteners are corrosion and water-resistant and can withstand extreme pressure, temperatures and weather conditions. They are pressure resistant to military spec 1,500 psi and sealing screws and rubber O-rings meet Military Spec NASM 82496. FDA O-rings are available.

Switch Boots, Crystal Seals
In addition to self-sealing fasteners, ZAGO manufactures switch boots that protect electronic switches used underwater from the damaging effects of salt water, wind and bacteria, and crystal seals that shield electronic devices from the elements and are crystal clear in color for instantaneous visibility. Both products are NEMA ready.

Reputable and Trusted
A registered ISO 9001:2015 company, ZAGO is made in the U.S.A. and meets DFARS, UL and MET U.S. criteria. ZAGO is also REACH, RoHS and California Prop 65 compliant. With engineering, a machine shop and manufacturing facility onsite, ZAGO can provide product samples usually within one-two days.

Accelerating Global Innovation
ZAGO tamper-proof, reusable, inherently green sealing fasteners and components seal everything from:
LiDAR systems, sensors and 3D cameras to pneumatic medical ventilators, invasive / non-invasive medical instruments, robots /co-bots, lithium batteries in electric cars and electric vehicle charging stations, the electrical cabinets at droneports, underwater vehicles, satellite imaging and more.

ZAGO sealing solutions and components are used in countless industries, including military and aerospace, electronics and enclosures, LiDAR, commercial lighting, medical devices, robotics and drones, industrial manufacturing, marine, energy generation and recovery and automotive. Clients include the U.S. Airforce, U.S. Army, U.S. Navy, GM, Ventec Life Systems, Apple, Google, Raytheon, Ferrari, BOSE, Teledyne Marine and others. ZAGO is available worldwide through distribution partners. Visit www.zago.com for more information.
