Thread, 15-425 G.P.I

Thread for replacement on apparatus using G.P.I. (Glass Packaging Institute) thread. These threads are used primarily on products manufactured in the United States. When a thread is designated as 20-400 it means that the diameter across the top of the threaded area is ~20mm. The numerical 400 designates a specific style of the finish. The following chart shows both the "T" and "H" dimension for use in identifying the thread. If the chart does not contain a dimension for style or size thread, this thread is not available. PLEASE NOTE: GPI THREADS ARE SOLD IN PACKAGES ONLY.
