Series 1500 Ultra-Spool expansion joints are a domestic, hand-built product for the most demanding of applications. A precision built product designed to provide exacting specifications for tube and cover requirements, pressure ratings, markings, and special options. The wide arch will provide much greater movement capabilities than standard narrow arch designs.
The tube can be constructed using a variety of elastomer products including EPDM, Chlorobutyl, Neoprene, Nitrile, Hypalon, Viton. When needed, a white PTFE liner can be added. Rubber tube thicknesses are approximately 1/4” thick for greater wear life. Reinforcing of multiple plies of polyester provide 225 PSIG working pressure in sizes up to 14” diameter. Thick steel body rings add hoop strength and assure high vacuum rating, even at extended temperatures. Each expansion joint has a permanently embossed brand on the cover with information including individual serial number for identification.
