Aztec Washer Company Poway, California Aztec Washer Company is a family-owned and operated corporation in Poway, California. It started in 1968 When its founder Henry DeGraan, became one of the first bonded washer manufacturers in the world. With his knowledge in the fastener industry, a few local distributors, and several orders to fill, Aztec quickly grew to a prominent position in the marketplace. With over 50 years of experience, knowledge, service, and loyalty to our customers, Aztec remains a global leader in the industry, with additional operations in the United Kingdom, Poland, Australia, and Mexico. The close working relationship established with our distributor networking ensures that the right parts, in the right quantities, are available to meet customer needs and satisfaction.

Master Seal® bonded washers solve a variety of problems in numerous applications, including: • Archery - Protects sensitive bow sights • Motorcycles - Protects fairings and components • Noise Control - Electromechanical automotive devices and motor mounts for compressors and other equipment • Fragile surfaces - Where crazing, cracking, and chipping are problems Cushioning and Vibration Control Other useful applications include: • Small and large appliances, vacuum cleaners and refrigerators • Heating ventilation/air conditioning (HVAC) equipment • Silos, tanks, bins, and other vessels for liquids and solids • Exhaust systems • Panel and enclosures • Environmentally controlled areas When installed for sealing, the materials in Aztec’s Master Seal® bonded washers against either a flexible or inflexible surface to permanently seal in or seal out any environment, natural or industrial. Facing materials are engineered to provide optimal resistance to weathering from ozone, ultraviolet light, and chemical agents. Aztec’s unique Master Seal® bonded washer products are designed to provide a permanent seal in various applications. Metal construction buildings • Automotive Aircraft • Glass and mirror installations • Architectural panels Other applications Include: • Metal roofs and siding where the expansion and contraction of metal require a permanent resilient seal • Dishwashers - To avoid leaks • Marine - Structural and electronic • Automotive - Air cleaner assemblies, engine blocks, heaters, emission control equipment, body sealing • Air filers - Dust control Over 40 Years of proven experience in testing and retesting compounded formulas have led to the perfection of Aztec’s Master Seal® bonded washers. Our bonded washers possess extraordinary elasticity and memory when cushioning and vibration control are needed. As the bonded washer is compressed and fastened against a substrate, the facing material is a permanent cushion. This feature protects the substrate from installation damage (spinning fastener and or torque) and vibration damage. When used for cushioning, Master Seal® bonded washers are especially effective on glass, plastic, fiberglass, porcelain, and painted surfaces. The cushioning effect eliminates scratching, crazing, chipping, and other surface damage. ALL WEATHER RESISTANT SEAL IN OR SEAL OUT…
Facing Materials NEOPRENE Polychloroprene - One of the earliest, and perhaps best known, man-made rubbers, is still one of the most versatile facing materials for sealing and cushioning washers. When properly formulated, it is highly resistant to sunlight, ozone, weathering, and aging while enjoying good memory and elasticity. Although its primary strength lies in its resistance to petrochemicals and certain other chemical families, Neoprene is a generalist, performing well in many applications. When contact with petrochemicals is of more significant concern than U.V. attack, Neoprene will do the job. SILICONE Addresses the next tier of sealing washer applications. Temperature extremes from - 115º F to + 480º F, exposure to specific chemical environments, or repeated sterilization cycles make silicone the most economical, high-performance choice. FLUOROSILICONES, VITONS, etc Aztec works with the most current elastomeric compounds for today’s most demanding sealing applications. These higher-cost materials are available to address the most demanding and specific challenges. NON-ELASTOMERIC Facings include asbestos substitutes, cork fiber, and soft metals, each useful in select applications. Because new applications demand specific combinations of performance and cost considerations, we can not list specifications for all uses. Our application engineers and chemists are prepared to discuss your requirements and deliver years of experience just for asking! EPDM Ethylene Propylene Diene Monomer - is an excellent, low-cost, ozone and weather-resistant. Elastomers possess superior aging characteristics. It is also highly effective when applications require heat resistance up to 350º F. Although the use of EPDM in direct contact with petrochemicals is not recommended, in construction applications where the primary hazards are ozone, ultraviolet light, and temperature extremes, EPDM is the elastomer of choice. Backing Materials Our selection of backing material involves three primary considerations: strength, corrosion resistance, and cost. Galvanized Steel It provides good strength characteristics and corrosion resistance similar to that found in standard commercial zinc-plated fasteners - all at the lowest possible cost. Stainless Steel Austenitic 300 Series or 18-8/A2 combines the optimum corrosion resistance and lowest available cost in a premium material. Its use is indicated wherever stainless fasteners are used or when a corrosive environment might attack lesser materials. 316 Stainless Steel Austenitic 300 Series with Molybdenum/A4 provides the highest corrosion resistance available in standard production materials. Due to higher cost, it is specified only in the harshest marine or industrial environments. Silicone-Bronze, Copper, COR-TEN® Other special property metals are available for use in specific applications and for Architectural aesthetics. Aluminum Aztec’s special alloys perform well when moderate strength and deflection requirements exist. For higher stress applications, improved strength and corrosion resistance may be attained by selecting specialty alloys and tempers such as 5052-H38. Using an aluminum Master Seal® also minimizes concerns of galvanic corrosion in specific installations. Aztec Offers various facing materials to address the distinctly different operating environments to which the Master Seal® bonded washer is exposed.
Seals Against any Surface Smooth or irregular, durable or fragile. Effective seal develops around the fastener when the sealant is forced inward during tightening. The fastener may be pre-assembled to Master Seal® bonded washer and installed as a unit. Effective with virtually all fastener types and sizes. Assemblies may be painted to match the color of fastened panels. The facing element provides a barrier against leakage at the surface and around the fastener. Protects surface from damage. It helps in reducing noise or vibration. Excessive Torque Causes reverse dishing. Leakage under seal possible Correct Installation Tight against the surface. Seal flows inward to seal minor fastener diameter and surface voids. Insufficient Tightening It is likely to cause leakage under the seal and around the fastener. Because of a unique bonding process, which bonds a strong backing material to a resilient facing material, Aztec’s Master Seal® bonded washers will perform a function that neither material could achieve alone. Where sealing challenges are presented, the conical design directs the flow of the elastomeric portion toward problem areas. When problems call for cushioning or vibration control, the facing material will also provide the solution. Features Include: • Quality elastomerics, meeting the need for elasticity, memory, temperature extremes, chemical, ozone and sunlight-resistance. • Conical design directs the flow of facing materials to form a seal conforming to both the fastener and sealing surface. • Full-face design cushions fragile surfaces and minimizes vibration. • Inside diameter sizes from -.120” to 2” and corresponding metric range. • Outside diameter sizes from -1/4” to 3” and corresponding metric range. • Choice of many backing materials. • Choice of various colors and finishes. • Choice of various facing materials. Master Seal® Bonded Washers are More than just Washers The strength of the backing provides load bearing compresses the seal vertically and protects it against turning the fastener head.
