C7T is the designation for model C7 with a Grade T NBR gasket. VSH Shurjoint grooved pipe systems consist of a wide range of groove couplings, fittings and valves for heating, compressed air and industry. VSH Shurjoint is less labor intensive, safer, cleaner and delivers consistent connection quality. The Model C-7 Outlet Coupling combines the features of a coupling and a reducing outlet. The C-7 is a joining device with an integral reducing outlet, eliminating the need for a mechanical tee or a reducing tee and couplings. The C-7 is available with grooved, male threaded or female threaded outlets. The C-7 coupling is recommended for fire sprinkler services and other applications up to 300 psi (20 Bar) depending on the size and schedule of pipe being used. The C-7 can be used for dry pipe systems or vacuum services up to -10 inHg or 254 mmHg which may occur when the system is drained. All Model C-7 couplings are comprised of an upper and lower ductile iron housings segment, EPDM rubber gasket and plated track bolts & nuts. Housings segments are supplied with our standard painted finishes, i.e. orange or RAL3000 red. Optional finishes such as hot dipped zinc galvanized and custom epoxy coatings are available.
VSH Shurjoint can be perfectly combined with other VSH systems such as VSH XPress, VSH SudoPress and VSH PowerPress
the 'Aalberts integrated piping systems' range covers a fully integrated system from 6 mm to 104 ”
