What is the primary function of the PGNG go/no-go gauge?
The PGNG verifies the finish diameter, thread pitch, and spacing of PET bottles and caps using a pass/no-pass gauging method, ensuring that PET bottle finishes conform to international beverage industry finish standards.

Which PET bottle finish standards does the PGNG cover?
The PGNG is available in configurations for PET-specific finish standards including 28mm PCO-1810, 28mm PCO-1816, 38mm PET/1690, and 28BPF, covering the most widely used finishes in carbonated and still beverage PET bottling.

How does the PGNG fit into a PET bottle production quality control workflow?
The PGNG is used to verify that PET bottle finishes from the blowing line conform to specification before capping, preventing capping failures caused by oversized or out-of-tolerance necks. It is typically used alongside AT2E's PPG-A/PPG-D perpendicularity gauges for a complete preform and bottle neck compliance check.
