JCM Flanged Adapters and Dismantling Joints

JCM 303 Fabricated Flanged Coupling Adapters JCM 304 Fabricated Reducing Flanged Coupling Adapters The JCM 303 Fabricated Flanged Coupling Adapter provides a simple means of joining plain end pipe to flanged fittings, valves and equipment. Ideal for installing flanged valves, backflow preventors, monitoring equipment and other pipeline accessories to be retrofitted into a piping system. Fabricated without pipe stops, the JCM 303 Flanged Adapter can be slid back on the plain end pipe for quick fitting installation and adjustment. Available in either size on size or reducing sizes (JCM 304), optional coatings and hardware and flange types.

Optional Flanges Available - ANSI/AWWA C207 Class D, ANSI 150 Drilling

ASME/ANSI B16.5 Class 150, 300 Weld Neck, Blind, Slip-on, Reducing, Threaded, Socket Weld, Lap Joint, Angle Face, Van Stone Concentric and Eccentric Flanges

Pipe Sizes 3” and larger

JCM 309 Fabricated Dismantling Joints Dismantling joints simplify installations and replacement of flanged fittings in retrofitting applications. JCM 309 Dismantling Joints provide the solution for adding, repairing or replacing flanged fittings within a flanged pipe system. Adjustable, slip joint design accommodates either wide gaps or close quarter installations and eliminates the need for precise measurements between flange connections. Restrained design standard. Available in sizes 2” (50mm) and larger, for ductile iron or flanged steel pipe systems. JCM 309 Dismantling Joints Offer: • Greater longitudinal adjustment ability speeds installations and reduce system downtime. • Accommodates future modifications and system adjustments. • Simplifies installation - one fitting integrates into system operating as flanged adapter and an adjustable spool piece.
