Hard Hat

Hard Hat™ was developed to bring greater security with higher break away torques, Hard Hat™ has a 200 inch pound break, per ASTM D5363 on a 3/8-16 fastener. Still manageable with hand tools on pipe fittings, this curable sealant will deliver about 800 inch pounds of off torque on ½ NPT pipe fittings. It has a beautifully matched break away and prevailing strength, delivered in what one of our engineers described as the “perfect viscosity.” It’s smooth slightly tacky nature, delivers a lubricating anti-galling film, which allows for maximum joint sealing, with minimal torque. Although iPipe Hard Hat™ is a PFTE containing anaerobic curing pipe sealant, because of its extraordinary properties we gave it bright yellow color. Hard Hat™ brings extra strength, for added security, in critical applications that are exposed to extra heavy abusive environments.

Dewald Engineered Adhesives anaerobic adhesives and sealants represent the latest generation in anaerobic chemistry. Anaerobic threadlockers remain liquid when they are exposed to the oxygen in air, but in the lack of air, (or anaerobic environment) these products quickly polymerize and fill the inner space between the surfaces. In a continuous quest to improve the performance of anaerobic adhesive’s and sealants, Dewald Engineered Adhesives works with leading edge engineers to push the chemistry forward, to increase cure speeds and bond strengths, and to design products that are able to cure on contaminated or inert surfaces and yet remain stable without special handling.
