Aztec Washer FAQs

Q: What is the difference between EPDM and Neoprene?

A: EPDM is commonly used in construction applications where the primary hazards are ozone, ultraviolet light and temperature extremes. Neoprene’s primary strength lies in its resistance to petrochemicals and certain other chemical families.

Q: Does your product qualify for the Buy American Act?

A: Yes, all of our products are essentially manufactured, processed and distributed from a point within the United States. Accordingly, our products comply with the domestic origin requirements as delineated in the Buy American Act.

Q: Are Aztec Washer products ROHS and DFAR Compliant?

A: Yes, all of products are compliant to ROHS, DFAR, and REACH. We also have other listings such as UPC, IAPMO and ICC.

Q: What is the warranty of Master Flash® pipe flashings?

A: Aztec Washer Company guarantees a 20 year warranty on all Master Flash® under normal weather and atmospheric conditions within 20yrs after date of purchase. See our 20 year warranty agreement at: http://aztecwasher.com/pdf/warranty.pdf

We also manufacture ICC listed Master Flash® with a guaranteed 35 year warranty. Remember, if your flashing doesn’t have a 35 year warranty, neither does your roof! See our 35 year warranty at: http://aztecwasher.com/pdf/35-year-warranty.pdf

Q: What type of sealant should be used when installing a Master Flash® pipe flashing?

A: We recommend WeatherMaster™ sealant sold at Aztec Washer Company which can be color matched to any of our Master Flash® colors available. It is VOC compliant, earth friendly, UV resistant, and extrudes down to 0º Fahrenheit. With its permanent flexibility, it won’t crack and due to its quick drying nature, it can even be installed in the rain!

Q: What temperature can Master Flash® products withstand?

A: Our EPDM Master Flash® products are tested to withstand +275ºF (+135ºC) with intermittent heat exposure and +212º F (+100º C) with continuous heat exposure.

Our silicone Master Flash® products are tested to withstand +500ºF (+260ºC) with intermittent heat exposure and +437º F (+225º C) with continuous heat exposure.

Complete specification data and testing methods are available upon request.

Q: Are there installation instructions or videos available?
