Socket Pipe Plugs Alloy Steel
Size: 1/8 through 1
Dry Seal: 3/4 Taper
Flush type: 7/8 Taper

Dry Seal
Description	A dry seal plug is one having a (0.750" diametral per 12") thread extending its entire length and designed to have its threads mesh tightly with those of a taperthreaded hole.  Both ends of the plug shall be flat and chamfered approximately 45".  The chamfer should extend slightly below the root of the thread and the edge between flat and chamfer should be slightly rounded.
Applications	The thread trunction is closely controller at root and crest to assure metal contact, preventing spiral leakage and forming a positive seal without the use of sealing compounds.  Dry seal plugs can be used in American Standard Taper Dry seal Pipe Thread (NPT) tapped holes, but for fullest protectionagainst leakage they should be used in dry seal tapped holes with are taper reamed before tapping.
Material	High grade alloy steel
Heat Treatment	Pipe plugs shall be heat-treated by quenching in oil from above the hardening temperature and tempered to achieve the hardness requirement listed below.
Hardness	Rockwell C36-43
Finish	Plugs are supplied with a standard black finish.
Flush Type
Description	A flush type plug is one having a tapered (0.875" diametral per 12") thread extending its entire length and designed to provide a flush condition with standard tapped hole (0.750" diametral per 12"). Both ends of the plug shall be glat and chamfered approximately 45 degrees.  The chamfer should extend slightly below the root of the thread, and the edge between flat and chamfer should be slightly rounded.  Six 1/16-27 plug, three identification grooves are permitted because of limited space.
Applications	A high pressure seal is achieved through the difference in taper, with dimensions precalculated to provide a higher sealing load near the large end of the plug and threads near the top of the tapped hole.  The flush type plug is preffered where high pressure are encountered and where protrusion is undesireable.
