COUPLINGWORKING PRESSURE RATING
on Light Wall Roll Grooved Steel Pipe
Maximum line pressure, including surge, to which a joint should be subjected on pipe roll grooved to standard roll grooving specifcation with coupling properly
assembled. For coupling performance on standard wall steel pipe, refer to individual Gruvlok Coupling performance listing.
* Rating based on larger pipe size.
