Description
JCM G212 transition gaskets are the self-centering, extra-wide gaskets of the JCM wide range coupling and flanged coupling adapter system. Stock one JCM ductile iron coupling or flanged coupling adapter and change only the gaskets to make a transition between A/C, cast iron, ductile iron, steel and PVC pipe; use the same size gasket on both ends to make a straight coupling.
Choose the coupling sleeve (the sleeve size is the number in the coupling part number, for example 210-0690 takes 690 gaskets), then the gasket for the pipe OD at that end.
Typical application: Transition and replacement gaskets for JCM ductile iron couplings and flanged coupling adapters.
Key Features
- Change gaskets, not couplings, to transition between pipe types
- Self-centering, extra-wide profile
- Certified to NSF/ANSI 61 Annex G and NSF/ANSI 372
- Fits JCM 210, 211, 212, 214, 262 couplings and 301, 306 flanged coupling adapters
- Oversized-sleeve gaskets for A/C and oversized pipe
What Ships and What It Needs to Run
Included: one gasket. A coupling takes one gasket per end; order two for a straight coupling, or one of each OD for a transition.
Coupling body, ordered separately. Pair with a JCM ductile iron coupling (Less Gaskets builds ship without gaskets) or flanged coupling adapter of the matching sleeve size.
Genuine JCM Industries equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
12-Month Warranty
Covered for 12 months from the date of purchase against defects in materials and workmanship. Keep the dated invoice as proof of purchase.
Working Pressure
Rated with the coupling. Pressure capability is set by the JCM coupling or adapter the gasket installs in.
