Gruvlok Flanged Grooved Flange
The Gruvlok 390201226 is a ductile iron flange with a grooved connection for an 8 in nominal pipe size. It measures 16 1/2 in outside diameter and overall length. The fitting meets A536 65-45-12 material standards and carries a Class 150 pressure rating.
Installers needing Class 150 grooved transitions
This flange suits piping systems that require a flanged by grooved joint at 300 psi maximum operating pressure. It operates from -40 Degrees to 230 Degrees F. Buyers who need a different pressure class or a threaded connection should look at other fittings.
A536 65-45-12 ductile iron construction
The body is cast from ductile iron to A536 65-45-12 for mechanical strength. The painted finish adds corrosion resistance in standard service environments. This material specification determines compatibility with the fluid and pressure requirements of the installation.

Questions about this item
What pipe size and schedule must I already have for this 16 1/2 in flange to connect properly?
This flange is built for an 8 in nominal pipe size; the schedule is not applicable, so it fits standard grooved pipe of that diameter.
Will the ductile iron A536 65-45-12 material and Class 150 rating hold up next to older steel piping in the same system?
Yes, the ductile iron body rated to 300 psi and Class 150 is compatible with existing steel pipe of the same pressure class and nominal size.
How can I confirm the flange is sealed and aligned after bolting it to the grooved pipe?
Pressurise the line up to 300 psi and inspect the painted ductile iron joint for leaks; the -40 °F to 230 °F range confirms thermal stability during the test.
