GRINNELL Gauges
This dimensional gauge is developed to check the A dimension (gasket seat) and B dimension (groove width) of grooved pipe.
A Dimension - Gasket seat
Select the proper size of pipe on the gauge. Place the gauge with the DIM A OK side on the grooved end of the pipe as shown on the drawing. If the gauge fits the groove should be acceptable. If the DIM A NOT OK side fits the grooved end, this groove is not made in accordance with GRINNELL specifications.
B Dimension - Groove width
Select the proper size of the pipe on the gauge. Place the gauge with the DIM B OK side in the groove of the pipe
as shown on the drawing. If the gauge fits, the groove should be acceptable. If the DIM B NOT OK side fits the groove, this groove is not made in accordance with GRINNELL specifications.
Please note: This gauge is not a calibrated tool and is to be used for reference only. To ensure accuracy, always check grooved end pipe with calibrated gauges or calibers.
