Air/Foam Hybrid Collars. The Air/Foam hybrid melds characteristics of air-holding and foam-insert collars. The key to the hybrid is the inflatable bladder that is compressed between the hull and the foam. By inflating the bladder the foam is forced away from the hull bringing the polyurethane sheath around the foam under tension.
Arizona heat facts. The highest temperature Phoenix has ever endured was 122 degrees back on June 26th, 1990. Even more amazing is the fact that our hottest overnight low was 96 degrees on July 15th, 2003. Phoenix's longest streak of temperatures at 110 degrees or hotter was 18 days in 1974.
On Aug. 14, Phoenix Sky Harbor International Airport recorded a high of 117 degrees, tying the Arizona capital's all-time record high for the month of August previously set Aug. 26, 2011. Like that date, the low was 93, so it also tied for Phoenix's warmest daily mean temperature on record for the month of August.
